Garmin's new sleep tracker offers a week of battery life

Engadget18-06-2025
Sleep tracking is nothing new in Garmin's fitness watches, but the company's latest wearable is a dedicated smart sleep band. The Index Sleep Monitor offers week-long battery life with continuous pulse ox tracking for monitoring your blood oxygen saturation while you sleep.
Garmin's tracker is worn on the upper arm — which should hopefully make it more comfortable — where it tracks a variety of metrics: skin temperature; light, deep and REM sleep stages; and variations in your heart rate and breathing. The data is then combined to provide an overall personalized daily sleep score that can be viewed in the Garmin Connect app. If you already use a Garmin smartwatch but don't sleep with it on your wrist, the Index Sleep Monitor is designed to add the missing metrics to the insights you're already getting from the watch.
Skin temperature tracking gives you a better idea of how your sleep environment affects the quality of your sleep, while flagging potential illnesses indicated by temperature changes. This metric also extends to menstrual health tracking, with skin temperature changes useful for tracking cycles, past ovulation estimates and offering what Garmin describes as 'improved period predictions.'
Garmin's Index Sleep Monitor will also monitor your energy levels, providing you with its 'Body Battery' measurements that advise you to take more rest when the reading is coming in low. Again, these insights should be more accurate and reliable when combined with a compatible smartwatch worn during the day. The sleep band will also track your stress throughout the night, and features a smart alarm that attempts to wake you gently during lighter sleep stages so you'll feel less tired.
The Index Sleep Monitor is available in S-M and L-XL sizes and costs $170.

I test Garmin watches for a living and this accessory improves every single one

I've been wearing and reviewing the best Garmin watches for many years and for most of that time I used them with a silicone band, usually the one they came with. This isn't a terrible thing to do — Garmin's silicone straps are more comfortable than most and are easier to clean and dry faster than fabric straps, so can be great for swimmers in particular. However, in the time I've been testing sports watches, nylon bands have become more and more popular, and once I started using one myself I've rarely wanted to go back to a silicone band. Even if you're not sure you'll prefer it, I'd recommend that any Garmin user picks up a nylon band for their watch just in case. You don't have to spend much to get one either. Garmin's own UltraFit nylon bands are expensive at $39, but you can find third-party bands very easily that cost a fraction of that price on Amazon and elsewhere —- the band I use most often is one I found on eBay, just because it's the exact shade of blue I wanted. This is the official option for those who want to get a nylon band from Garmin. The UltraFit band comes in four colors and there are three widths — 20mm, 22mm and 26mm — so make sure you get the right one for your Garmin watch. Garmin does now ship some watches with a nylon band as standard, like the Garmin Enduro 3 and Garmin Venu X1, and I hope this becomes the norm going forward. Or, ideally you get a silicone and nylon band in the box — given the high price of the best sports watches, this would be a nice touch from any brand. The main reason to use a nylon band is comfort. They don't rub the skin or irritate it in any of the ways silicone bands can, and adjusting them is easy since you can pull them exactly as tight as you want, rather than relying on a standard band having a hole in the right place for you. This is a major plus point for those who find they get rashes from silicone bands, and even though I don't suffer from that myself, I do get heat rashes in the summer and find nylon bands more comfortable to wear than silicone bands when I do. Another advantage of the secure fit is that I tend to find I get slightly more consistent heart rate monitoring from watches when using a nylon strap. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. I can tighten the optical sensor snugly against my wrist, and the watch doesn't move around at all during runs in particular. With silicone bands it's sometimes trickier to get the right snugness of fit to get a reliable heart rate reading. While I still default to using a chest strap heart rate monitor when accuracy is essential, nylon bands can help improve the often unreliable heart rate tracking you get from sports watches. One common fear people share when I recommend nylon bands is that they'll feel slimy and unpleasant to wear after showering or swimming with the watch, whereas you can quickly dry off a silicone band. Nylon bands do dry more slowly than silicone bands, but I wash them after a workout then rub them with a towel, and by the time I'm out of the shower myself I don't find them any worse to wear than a silicone band. You can (and probably should) also throw them in with your washing occasionally to get a deep clean, if you're worried about them retaining germs more than a silicone band. To avoid the wet band problem entirely, you can also pick up a set of two and swap between them after a shower, so they can dry entirely between uses. These nylon bands are easy to use with Garmin watches and you get two different colors included for the price. I've used Albanen bands myself for many years and they are almost as nice as the official Garmin UltraFit band, and you get two for half the price of one UltraFit strap. I've accumulated a lot of bands now to suit different watch styles and sizes — like running shoes, you can never have too many.

If you're moving from Apple to Garmin, you'll want to install this watch face

There's a lot to consider when moving from Apple Watch to Garmin — sure, you'll get a better battery life and more health tracking features, but one thing you might miss, as well as answering calls and texts from your wrist, is closing your rings. The good news is, you can still close your rings using this Garmin watch face. I review the best Garmin watches for a living, and while this is the watch face I always download, the Goals screen is super popular, and mimics Apple's rings. The best part is, unlike Apple, you can completely customize what your rings measure. Like all custom Garmin watch faces, you can download the watch face, named Goals, from the Connect IQ app. You can download a free trial of the watch face first, and then it will cost $1.99/£1.99. Once you've downloaded the face, you'll be able to move it from watch to watch, if you ever choose to upgrade your Garmin. Here's why I recommend it. I've been reviewing the best fitness trackers for the past decade, and I'm the first to admit, the Apple Watch rings are extremely motivating. Far more motivating than my watch randomly buzzing throughout the day, telling me to move. I've been known to go for a walk at 10 pm just to close my move ring, and the same applies with the Garmin goals, which I love seeing my move throughout the day. One big step up from the move, exercise, and stand rings you'll find on the Apple Watch is the ability to customize your goals to ones that are important to you. The goals watch face lets you pick from a huge list of stats, including all of the obvious options like steps, movement, and calories, but also more unique goals, such as floors climbed, monthly walking minutes, and time to recover in hours. As a marathon runner, it's always helpful to see my active calories — a stat you can't see on most of Garmin's built-in watch faces. This helps me ensure I'm eating enough when my training plan involves high mileage runs. If you're looking to lose weight, it's also a helpful metric to keep an eye on, as you want to ensure you're in a calorie defict, burning more calories than you consume. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. I've installed the Goals watch face on my Garmin Forerunner 570, Garmin Forerunner 970, and Garmin Epix Pro, and have not experienced any difference in battery life while using it. It looks fantastic on the bright, AMOLED screen, and I appreciate the option to customize the colors of the bars to suit my style.

Garmin Venu 3 review: A great fitness tracker, but it falls short as a smartwatch

For the last four months, I've been testing the best Garmin watches available. The Venu 3 is Garmin's most advanced smartwatch yet, and it's built on the same top-tier fitness foundation the brand is known for. In addition to having a built-in microphone and speaker, it has best-in-class GPS, industry-leading heart rate tracking, and deep recovery metrics. During testing, I found the ability to answer calls and texts from my wrist was nice, but the advantages felt pretty limited in this model. Moreover, if your goal is to track workouts, stay on top of your stress and sleep, and see who's texting or emailing you without your phone nearby, I think the Vivoactive 6 is going to be a better pick — at a better price — for the majority of people looking for a smart fitness watch. (Check out our full Vivoactive 6 review.) While the Venu 3 is all-in-all a solid watch, after testing it for the last few months, I don't think it's the best value for your money. Here's why. What I found after 3 months of testing It's built on Garmin's fitness tracking power. Garmin has some of the best fitness tracking technology, based on a long-standing foundation of very accurate GPS and heart rate detection. With this core, the Venu 3 has a lot of the same features and abilities that make Garmin's other lifestyle watches great for fitness devotees: it tracks your steps, sleep, and stress automatically; has 30 pre-loaded activity profiles you can manually use to track workouts with helpful in-the-moment stats like heart rate, pace, and distance; it uses your health and activity data to determine your "body battery" energy and recovery levels throughout the day; and it has a digital coach for training and improving your sleep. Every morning, the Venu 3 delivers a morning report with sleep quality, body battery, and a daily suggested workout. And, like most every Garmin watch, the face and data fields are fully customizable in the app so you can tweak the watch to match your needs. It's sleek, intuitive, and has a great battery life. The Venu 3, like most Garmin models, has many other perks than the foundational tech: It has an exceptionally long battery life (14 days in smartwatch mode, or 26 hours in GPS mode), which means you can more continuously track sleep and daytime stress, and you can leave your charger behind for short travels. The AMOLED display is crisp and vivid, the interface intuitive, and the case design more refined than past Garmin watches (though it looks very similar to the Vivoactive 6). You can customize the watch face so it looks as sporty or as sleek as you prefer. I also appreciate that it comes in two sizes, the smaller Venu 3S with a 41mm screen and the Venu 3 with a 45mm screen. It's a smarter watch…sort of. The biggest headline that sets the Venu 3 apart from Garmin's other watches is that it has a built-in microphone and speaker. This means you can take calls and use your phone's voice assistant directly from your wrist — something the Vivoactive 6 and Garmin's less-smart watches can't do. On one hand, I found this feature genuinely convenient during moments like taking quick "need anything on my way home" calls from my husband, or replying to a text while hands-deep in pie crust. A quick voice reply definitely beats tracking down my phone for a short answer or trying to swipe with messy fingers. I also found the voice-to-text feature worked just as well (if not better) than using Siri to dictate. That said, there's a big catch: your phone has to be unlocked for you to do anything beyond responding to an incoming text or answering a call. Unlike with, say, an Apple Watch, the Venu 3 can't initiate a text to someone, reply to a text from earlier in the day, or even add something to your Notes app without your phone being unlocked first. I found this to be quite frustrating; this limitation really narrowed how often the on-wrist reply function was actually usable. The voice assistant access was also finicky — sometimes I'd press and hold the middle button and it would say "connecting to voice assistant," only to immediately go back to the home screen. In short, it's not quite the seamless smart assistant experience you get from an Apple Watch or Galaxy Watch. If you're an Android user, you have a little more to work with: You can access quick-reply features, and these only need Bluetooth, not voice assistant, so you can shoot a pre-set canned reply even if your phone is locked. Why it's not worth $150 more than the Garmin Vivoactive 6 Having tested both of these watches over the last three months, I can tell you Garmin's two smartwatches are very, very similar. The main difference: The Venu 3 is slightly smarter but also significantly more expensive than the Vivoactive 6. Here's what $150 more will get you with the Venu 3: Ability to take phone calls on-wrist. Ability to use voice assistant and reply to incoming texts on-wrist. Ability to initiate pre-set texts on an Android on-wrist. 14 days of battery life vs. 11 days in the Vivoactive 6. 30 preloaded activity profiles vs. 80 in the Vivoactive 6. Slightly higher display resolution. A built-in barometric altimeter for more accurate elevation tracking. In my opinion, unless you take quick phone calls a lot or use voice assistant all the time (and have your phone unlocked to do so), the Vivoactive 6 is a much better value for your money. How it compares to other smart watches If you are more interested in having a great smartwatch that does a good-enough job at tracking workouts, then your decision is really between the Garmin Venu 3, the Apple Watch Series 10, and the Google Pixel Watch 3. (After testing the Fitbit Versa 4, I can confirm it doesn't have a seat at this table.) All three watches are a similar price ($400 to $500), have a sleek and clean design, and have an intense, visually rich display (the Venu 3 and Pixel 3 use AMOLED, while the Apple Watch 10 uses retina OLED). The Venu 3 has a significantly longer battery life (14 days vs. 18-24 hours), a far more accurate GPS, and far more accurate heart rate sensor than either competitor. Overall, this means the Venu 3 is going to be better at tracking your health and fitness and delivering deeper, more insightful metrics than the Apple Watch Series 10, including personalized coaching for free in the Garmin app. That said, the Apple Watch Series 10 does a good enough job at tracking workouts for most people (and auto-tracks them, which Garmins do not), is very good at analyzing sleep, and is way better at being a smartwatch for iPhone users compared to the Venu 3. The Apple Watch integrates better with the iPhone ecosystem, so you have more apps on-wrist (including navigation from Apple Maps), access to Siri, and voice control without needing to unlock your phone. You will have to charge it every 1-2 days, though. The Pixel Watch 3, meanwhile, integrates much better with the Android ecosystem than the Venu 3 — you can access more apps and Google Assistant from your wrist versus just receiving notifications and responding to texts and phone calls. The Pixel Watch is built on Fitbit's technology, so its workout and sleep tracking are pretty good, though it can't compete with Garmin's GPS or recovery insights. And, like the Apple Watches, the Pixel 3 needs to be charged every 1-2 days versus the Venu 3's 14-day battery life. For more picks, check out our guide to the best smartwatches and best fitness trackers. The bottom line The Venu 3 may be Garmin's most advanced smartwatch, but it's not $150 smarter than the Vivoactive 6. While it's nice to have an on-wrist speaker and mic sometimes, the need to unlock your phone for access is too much of a limitation for us to justify spending $450 on this watch. If fitness is your priority, the Vivoactive 6 is a great wearable with basic smartwatch functions (e.g., on-wrist notifications, Garmin Pay, music control) and way more activity profiles, all at a more affordable price than Apple or Google watches. However, if an advanced smartwatch is your priority, you may be happier with an Apple Watch Series 10 or Google Pixel 3 for a similar price to the Venu 3.
