I Wore Two Oura Rings to See If the Finger You Use Actually Matters

I’ve always preferred to wear my Oura ring on my ring finger. The company says that “for optimal performance and accuracy,” it’s best to wear it on your index finger, but that any finger can work. And if you ask longtime Oura users, you’ll get a variety of opinions. Does it really matter which finger you use? I realized I have the perfect way to test this—I have two gen 3 rings that fit my index and my ring fingers. I wore both for nearly two weeks to compare their readings and answer the question once and for all. 

How I set up my experiment

As I explained in my four-year retrospective, I’ve worn quite a few Oura rings over the years. My current unit is a gen 3 ring (the slightly older model) that I wear on my ring finger. I also had a gen 3 that fit my index finger, so I could wear both to bed for a few days and compare their readings. 

I actually wore three rings, but left one of them off my results because it turned out to be redundant. This one was a duplicate of the one I had on my ring finger, so I wore it on the other hand’s ring finger. It was a nearly-dead one that I had replaced when its battery wore out. It still had just enough juice to make it through each night’s sleep so long as I charged it the next day. The readings were pretty much the same as my other ring finger, though, so I left this data off my results chart for clarity’s sake. 

For this experiment, I needed to pair each ring to a different account on a different phone. The things I do for you, dear readers. Since the accounts were all working from different (or nonexistent) baseline data, I avoided any scores that the app calculates based on your personal history. I stuck with readings like resting heart rate, heart rate variability, and sleep time. The one score I kept was sleep efficiency, since that combines multiple measurements from the same night.

I’ve always felt like my ring finger readings are as good as my index finger readings, but now I have data to prove it. Look at these charts! The readings are often identical, and always close. There was one day where the two readings differed—it’s the very last day, with different respiratory rates and sleep efficiency. On that day, my second ring-finger ring (data not shown) matched the other ring-finger ring, suggesting that it’s the index finger that was the outlier.

Overall, the different fingers give readings that are much closer to each other than the different devices from this comparison (for that experiment, I wore Oura, Garmin, Whoop, Apple, and Fitbit devices at the same time).

Any of the three placements I used would be perfectly good for daily wear. So why does Oura say your index finger is best? I reached out to the company for more information.

What Oura says 

The gen 3 and 4 Oura rings work on any finger, an Oura spokesperson told me by email, so long as the ring fits “tightly and securely” around the base of the finger. So why the preference for the index finger? It turns out that’s the finger where most people have the easiest time getting a good fit. 

Specifically: “We suggest avoiding fingers with large knuckles where the base is significantly narrower, which can affect fit and sensor contact. This is why we generally recommend the index finger. If that’s not comfortable or preferred, the middle or ring finger are also good alternatives. All three fingers have larger blood vessels, which help optimize PPG pulse monitoring.” (PPG refers to photoplethysmography, the optical sensor system that picks up your pulse from your finger.)

So if your ring finger has a big bony knuckle, you’ll need a larger size ring to get over the knuckle, and that ring won’t be able to sit snugly against the base of your finger. I have no problem getting a secure fit on my ring finger, but I can see that my thumb has a large enough knuckle it probably wouldn’t work well with the ring. 

Another issue with sizing is that the Oura ring doesn’t come in half sizes, so you may not be able to find the perfect size for your preferred finger. That said, the gen 3 rings feel about a half-size smaller than the gen 4 rings at the same numbered size, so playing around with both sizing kits may help you to find the perfect fit if you’re not picky about which version of the ring you end up with.

Six Ways to Use Landscaping to Enhance Your Home’s Security

Although home burglaries are trending downward overall, there are still more than 800,000 break-ins every year. Aside from the potential damage to your property and the loss of your belongings, there also the concern for your family’s safety—no one wants criminals wandering around your house.

The obvious solution is to go with technology—alarm systems and security cameras. While these kinds of systems can definitely help defend against unwanted guests on your property (and give you peace of mind), there’s more you can do to keep your home secure. Your landscaping is a surprisingly key element of your home’s security—or it can be, if you plan it thoughtfully. Here are a few simple ways your home’s exterior design can help defend it against intruders.

Keep your home’s entrances visible

The first thing to consider when it comes to security and landscaping is visibility. A lot of tall, lush plants can give you a feeling of cozy privacy—but it also offers a lot of places for people to conceal themselves. Trimming hedges, shrubs, and other plantings down to about 2 to 3 feet in height will ensure you have a good field of vision around your property, and can help eliminate those hiding spots and make it easier to actually use those security cameras you paid for.

Having a lot of plants around windows and doors can give you a lot of privacy and shade, but it also means someone can get up close to your house to work on your door and window locks without being seen from the street. Your neighbors can’t help you if they can’t see what’s happening. And dense landscaping around your front door means someone can conceal themselves in order to wait for you to come home or open the door.

To make your windows and entryway more secure, keep them clear. If you’re using defensive plants, keep them trimmed low and set them back from windows and doors. You should be able to see the area immediately around your apertures easily from a variety of angles.

You can also increase visibility by avoiding opaque features like walls or fences, and instead going with see-through choices like picket or chain-link fences or lattices.

Choose thorny plants

One way to weaponize your landscaping against trespassers is to place “defensive” plants around access areas like first-floor windows. Thorny, prickly plants placed thickly around these areas create a natural barrier to anyone trying to creep around your house. It might not have the same visceral excitement as releasing a bunch of hounds, but it will definitely make a trespasser think twice as they nurse their wounds.

Some examples of good defensive plants include cacti (including some mild-weather species like Prickly Pear), thorny rose bushes, Whale’s Tongue agave, or spiky plants like Barberry. Whatever climate or design you’re working with, there’s a plant that will make life uncomfortable for anyone trying to get close to your house.

Trim back your trees

If you’ve got trees as part of your landscaping, you should keep them away from your house (about 8 to 20 feet, depending on the size of the tree) for a lot of very good reasons (root issues with your foundation or roof damage, for example). But if your trees are closer than that, or if they’re mature and their branches have crept closer to the house, you should hire an arborist to cut them back. Trim both horizontally (so no one can shimmy their way to a window or to get on your roof) and vertically (so there are no branches lower than seven feet or so off the ground) to prevent someone from climbing up. Untrimmed trees can provide hiding places or act as ladders for thieves and other intruders, so trimming them regularly is a very good idea.

Skip the trellis

You might like the visual of a climbing plant snaking its way up your home’s walls, but if that includes a trellis or lattice you should reconsider. A trellis or lattice attached to an exterior wall (or leaned up against it) is essentially a ladder that someone can use to climb, gaining access to an upper floor window.

Use gravel for ground cover

One way your landscaping can increase your home’s security is by making it more challenging for intruders to sneak around. Rough gravel used as a ground cover around access points like windows will be noisy when walked on, making it a lot more difficult for someone to get close without being noticed. It’s not going to be as effective as an alarm system, of course, but in the dead of night an unusual noise might alert you—or your dog—to the presence of an unwanted guest outside.

Add lighting

One of the more obvious ways your landscaping plan can improve your home’s security is by adding a lot of lighting, especially motion-activated lights. Being able to see your outdoor spaces clearly makes it less likely someone can gain access to your property undetected, and a sudden flood of light will deter trespassers hoping for the cover of darkness. When planning your landscaping, make sure to include robust lighting to make it as safe and secure as possible.

USDA Freezes Funding, Promises Further Action If Maine Continues Violating Federal Law

(WASHINGTON, D.C., April 2, 2025) — Today, U.S. Secretary of Agriculture Brooke Rollins fulfilled the promise of Title IX in pausing federal funds for certain Maine educational programs. Secretary Rollins sent a letter (PDF, 612 KB) to Maine Governor Janet Mills announcing the pause and an ongoing review of federal funding that the state of Maine receives from the United States Department of Agriculture (USDA).

My Favorite Amazon Deal of the Day: The Kindle Paperwhite Kids

We may earn a commission from links on this page. Deal pricing and availability subject to change after time of publication.

If you’ve never considered the Kindle Kids e-reader because of the label, you’ve been missing out on some sweet perks. The 16 GB Amazon Kindle Paperwhite Kids is $139.99 (originally $179.99), the lowest price it has ever been, according to price-tracking tools. Here’s why this is a great deal for everyone—not just kids.

The kids’ Kindle version includes a free case (about a $30 value), an ad-free experience ($20 value), six months of Amazon Kindle Kids + subscription ($36 value), and a two-year warranty (as opposed to the one-year warranty on the standard version). All that value for $20 less than the “adult” version is a no-brainer.

The cases for these models are obviously tailored for kids, but it’s hard to argue with free. The Amazon Kindle Kids + subscription will charge you automatically after the first six months, but you can cancel it beforehand. On these Kindle models, the kids’ mode feature is turned on by default. You can easily turn it off in the settings, but this will bring the ads back to the lock screen—the Kindle Kids also has some cool features even adults will appreciate, like the awards feature, as this video explains.

With the six months of Amazon Kindle Kids + subscription, you can get unlimited access to thousands of kids’ books, including all of the Harry Potter series. The Paperwhite Kindle hardware is the same as the adults, including that it’s waterproof, has adjustable warm light, a 12-week battery, and Audible access through Bluetooth. You can read the full review of the 2024 Amazon Kindle Paperwhite Kids from PCMag here. If you still don’t know which Kindle is best for you, check out our complete breakdown.

We Finally Know What the Nintendo Switch 2 (and Its Games) Will Cost

Nintendo has never been known for high-performance hardware, but that certainly hasn’t hurt its bottom line—especially in the Switch age. The company’s decision to use more basic components for the Switch back in 2017 helped keep the console cheaper than any of its competitors. It’s tough to get too hung up on the lack of 4K 60fps support when you can play the latest Zelda on a handheld that can cost less than $200.

But lo, a new Switch is here, and with it, a new price. The Switch 2 is, indeed, a more powerful version of the Switch, and comes with a number of advantages: a larger 1080p HDR display with a 120Hz refresh rate, a dock equipped with a fan to support 4K 60fps gameplay, magnetic Joy-Cons with a “mouse mode” for tabletop controls, among other neat perks. Of course, Nintendo isn’t giving those perks away for free, nor is it offering the Switch 2 at the same price as the Switch 1. If you want to order Nintendo’s latest console, you’re going to have to pay more—for everything.

How much does the Switch 2 cost?

The Switch 2 retails for $449.99. If you want the bundle that comes with a digital copy of Mario Kart World, that costs $499.99. That isn’t cheap, especially when you can pick up a Switch OLED right now for $250. The original Switch retailed for $299.99 too, though that’s roughly equal to $390 when adjusting for inflation, so the difference isn’t quite so dramatic.

We’ll likely never know exactly what went into the pricing decision for the new Switch, but it’s certainly possible tariffs played a big role. The Switch 2 sold in Japan, for example, costs 49,980 yen, which is just over $333 today. The Mario Kart bundle is 53,980 yen, or roughly $360—still cheaper than the original Switch’s MSRP in today’s money. Ouch.

How much are Switch 2 games?

There’s a $50 difference between the standalone Switch 2 and the Mario Kart World bundle, so you might imagine that’s what the game costs. Unfortunately, no: Mario Kart World is actually $80. Not all games may cost this much, however. According to Geoff Keighley, Donkey Kong Bananza retails for $70. These are the only two games with retail prices, so we’ll have to see how Nintendo handles MSRPs with future games. (While we don’t know the exact prices, we do know a lot of the games launching for Switch 2.)

However, physical games might actually cost more. Reports show that Nintendo’s European versions of Mario Kart World cost €79.99 for a digital copy, but €89.99 for the physical cart. $90 for a physical game card seems astronomical. We’ll need to wait and see if Nintendo rolls out any other pricing information.

Switch 2 accessories

Nintendo’s official Switch 2 accessories page is live, which means we can see all the MSRPs for the console’s newly-announced add-ons. Here’s what you can expect to pay for each:

  • Switch 2 Pro Controller: $79.99

  • Left and Right Joy-Con 2 controllers: $89.99

  • Joy-Con 2 charging grip: $34.99

  • Joy-Con 2 strap: $12.99

  • Joy-Con 2 wheel (two-pack): $19.99

  • Switch 2 camera: $49.99

  • Switch 2 dock: $109.99

  • Switch 2 carrying case (with screen protector): $34.99

  • Switch 2 all-in-one case: $79.99

  • Switch 2 AC adapter: $29.99

Your Apple Watch Alarm Doesn’t Have to Be Silent

On Monday, Apple released iOS 18.4, iPadOS 18.4, and macOS Sequoia 15.4 for compatible devices. But Apple Watch owners might have noticed watchOS 11.4 curiously missing from the list. Apple pulled the update at the last minute, something of a rarity from the company that likes to release all software updates together.

But now, the new watchOS update is finally available to everyone, and the slight delay was worth it. This update enables a feature that many Apple Watch users have wanted for a long time: the ability to break through Silent mode when an alarm goes off.

The iPhone already does this really well. You’re in Silent mode, or you have Do Not Disturb enabled, but your morning alarm still sounds. Apple Watch, on the other hand, had no such option. So if you like using a Silent mode to protect yourself from notifications and other dings, you had to make do with the vibration alarm. Starting with watchOS 11.4, you can keep your notifications at bay, while relying on an audio alarm to sound alongside the gentle vibrations.

Which Apple Watches are supported?

The feature is available only for users who have watchOS 11.4 or newer. That means it’s only available for Apple Watch Series 6 and above, Apple Watch Ultra and above, and the Apple Watch SE 2. If you’re rocking the original Apple Watch SE, or the older Series 5 Apple Watch, you’re left out in the cold here.

If you have one of the supported Apple Watches, first update your iPhone to iOS 18.4, and then head over to the Watch app. In the My Watch tab, go to General > Software Update. Here, download and install the latest watchOS 11.4 update.

How to enable Break Through Silent Mode for any alarm

The feature isn’t necessarily ideal, since you need to enable it for every alarm that you set. The news is good if you rely on the same repeating alarm each day, since those settings are preserved, but if you frequently set new alarms, make sure this setting is enabled each time. Hopefully, Apple will create a system-wide toggle for this, or even make this a default option down the line.

Go to the Alarms app on your Apple Watch, and choose the alarm that you want to customize. Here, in the Edit Alarm menu, scroll down and enable Break Through Silent Mode.

How to enable Break Through Silent Mode for Sleep Mode

If you wear your Apple Watch in bed, chances are you use Sleep mode, and the alarm associated with your sleep schedule. If you want to break through Silent mode here, you’ll need to enable the feature separately.

On your watch, open the Sleep app and scroll all the way down to your alarm schedule. You’ll see two alarms here—one for setting your Bedtime, and one for Wake Up. Choose one of the alarms, and in the Edit Schedule view, scroll down and choose Sound & Haptics. Here, enable Break Through Silent Mode.

The Four Best Alternatives to Zelle

Zelle, the digital payment platform that allows you to send money directly to friends and family, has shuttered its standalone app. But while the Zelle app is no longer, you can likely still send and receive money with Zelle through your bank or credit union—Zelle is already integrated into over 2,200 bank apps, and you can use this search tool to find out if yours is one of them.

Otherwise, you’ll have to send money using another tool. Here are four of the best Zelle alternatives for peer-to-peer payments.

Venmo

Venmo allows you to request money or pay other users and send up to $60,000 a week once you’ve verified your identity within the app. You can transfer funds in your Venmo account to your bank account for free if you’re willing to wait 1–3 days, or instantly for a 1.75% fee. Funds sent from from your Venmo balance or linked bank account/debit card are fee-free, while money sent using your credit card incur a 3% charge.

Note that you should update the default privacy settings on Venmo to ensure your transactions and account information aren’t publicly viewable.

Venmo is available for iOS, Android, and on the web.

PayPal

PayPal is a well-established digital payment service that is useful for sending and receiving money from friends and contacts as well as making purchases online. There’s no fee to send money via the “Friends and Family” function from a linked bank account or using your PayPal balance, and standard withdrawals are also free (like Venmo, instant transfers incur a 1.75% fee).

There are fees for international transactions and currency conversions, as well as personal transactions made with credit cards.

PayPal is available for iOS, Android, and on the web.

Cash App

Cash App is a peer-to-peer platform similar to Venmo. You can send money from a linked bank account or debit card to other Cash App users—if the recipient’s phone number or email isn’t linked to an account, they’ll be prompted to create one to claim the funds—for free. Standard transfers are also free, and instant transfers from Cash App to your bank incur a 0.5%–1.75% fee.

Cash App can also be used to send and receive bitcoin.

It’s available for iOS, Android, and on the web.

Apple Cash

Apple Cash is a built-in payment function for sending money to other iPhone users via Messages, Wallet, or Tap to Cash. Apple Cash is a digital card held in your Apple Wallet, and you can transfer funds out to your linked bank account (standard timing and free) or debit card (instant for a 1.5% fee). Apple Cash allows you to send or receive a maximum of $10,000 per message, with the same limit in a 7-day period. If you have an iPhone, you can pay someone using Apple Cash from within other apps, including Messages.

Apple Cash is integrated into iOS and available on the web.

How to protect your privacy with digital payments

The apps we’ve listed here have various privacy and security protections, like encryption and secure authentication, but peer-to-peer payment platforms are still targets for scammers. Make sure you only send funds to trusted contacts, and enable settings that keep your money safe, like identity verification and limiting who can see your account and request funds from you.

USDA Announces Agricultural Trade Promotion Programs for FY 2026

(WASHINGTON, D.C., April 2, 2025) — The U.S. Department of Agriculture (USDA) is launching agricultural trade promotion programs for FY 2026 and accepting applications for four export market development programs. USDA’s Foreign Agricultural Service has opened funding opportunities for the Market Access Program (MAP), Foreign Market Development Program (FMD), Technical Assistance for Specialty Crops Program (TASC), and Emerging Markets Program (EMP) that will help U.S. agricultural producers promote and sell their goods internationally. This action follows U.S.

My Favorite Amazon Deal of the Day: This Bose Smart Soundbar

We may earn a commission from links on this page. Deal pricing and availability subject to change after time of publication.

The Bose Smart Soundbar wasn’t very well received by reviewers when it came out last fall, citing small improvements for a larger price tag. But now with a $100 discount, we can have a serious conversation about who it’s good for. You can get the Bose Smart Soundbar for $399 (originally $499), the lowest price it has been, according to price-tracking tools.

The Bose Smart Soundbar is the successor to the Bose Smart Soundbar 600, which was already a very good soundbar, so needless to say, standards were high. Bose essentially made a new soundbar with more modern features, but didn’t upgrade the hardware, bringing into question the steep price increase, according to PCMag’s and many other reviews. If you already have a 600, it’s not worth upgrading even with the discount. However, if you’re looking for a modern premium soundbar that has enough bass to not need a subwoofer, then consider the new Bose Smart Soundbar.

Like most premium speakers, the soundbar doesn’t need a subwoofer, because it creates its own bass, but the output will never match that of a dedicated subwoofer. This works well for bedrooms or small apartments. But keep in mind you can always add a subwoofer and/or rear speakers. Speaking of which, if you own Bose Ultra Open Earbuds, you can connect them to the soundbar to work as rear satellite speakers, creating a pseudo-surround-sound system (only for you, though).

As the name implies, this is a “smart” soundbar, with wifi, meaning as long as you’re in the same wifi network, you can stream your media to it with AirPlay or Chromecast. They also work as a smart speaker since it comes with built-in Alexa. The instrument separation is what makes this soundbar shine, which goes hand-in-hand with the AI Dialogue Mode feature for dialogue enhancement. But, if you can afford to spend a bit more, the Sonos Beam Gen 2 is the best stand-alone soundbar you can buy.
