Garmin Index Sleep Monitor

This sleep monitor gives you exactly what you need to track your sleep. Way better and way cheaper than the Oura Ring or the Whoop device. You pay one time and there are no subscriptions. Also, the material is very comfortable. I don’t even notice while Im sleeping.

While this band is much more comfortable than sleeping with your Garmin wrist device overnight, it fails to live up to the core promise Garmin makes: it does not contribute to the physiological model your watch creates, so you end up having your watch's model and the sleep band's model that are disconnected. Body Battery, HRV Status, Training Status, and V02 Max had to completely reset when I started wearing this, and it wasn't until I dug deeper that I learned that the watch and sleep band don't work together to create a model - they create separate models. Until Garmin creates a better device ecosystem where their devices work together to create the physiological model, I'll be considering this sleep band a waste of money and would not recommend that anyone relying on Garmin for data on training progress. If you're casually tracking your body data and are not relying on the model for training, it could work just fine but I would advise leaving the watch on at night and putting it on in the morning while you still have the sleep band on so they both sync with the Connect app before removing the sleep band. Garmin - please fix your device ecosystem or give more clear information that the devices work to SEPARATELY track physiological data rather than working TOGETHER to create a comprehensive model.

I bought this hoping for better results and I find the results to be more consistent than the Fenix watch. I have no way to determine the accuracy. It is certainly comfortable to wear to bed. The shortcoming seems to be battery life; I am recharging every 4-5 days. You would think that Garmin could have designed this with a longer lasting battery.

I have sleep apnea and vestibular migraines which can be triggered by lack of quality sleep. My CPAP machine only tells me how long I've been in bed with the machine on, not how long I have been asleep. I had a SleepOn ring for almost 3 years before the battery wouldn't last through the night anymore. I do NOT want to pay hundreds of dollars a year on a subscription so this seemed like the best choice. Things I like about the Index Sleep Monitor: From a well reputable company; the device goes around my arm so it makes washing my hands easier when I get up to go to the bathroom; no subscription fees; reasonably priced compared to the competition; good battery life, which means fewer charge cycles per year and hopefully longer life than my SleepOn ring. I'm still getting used to the app but it provides me the information that I want and syncing with my iPhone is fast and easy.

I really wanted this to work, but after more than a month of troubleshooting, I can’t recommend this product to most Garmin users. The only real positive: it is genuinely comfortable. If you hate sleeping with a watch on, this is well designed and easy to forget you’re wearing it. The major problem: functionality is extremely limited unless you own Garmin’s very latest watches (for example Fenix 8 and a small handful of newly released models). If you own anything older, including premium models like the Epix Pro Gen 2, the Index Sleep Monitor does not reliably integrate with core training metrics like Training Readiness and stress history. Sleep and HRV data may record, but critical components needed for Training Readiness frequently fail to sync or are ignored entirely. Garmin’s own forums are full of reports of missing sleep, missing recent stress, or incomplete readiness scores when using this device with anything other than their newest watches. What makes this especially frustrating is that Garmin does not clearly disclose these limitations anywhere in the product description. The marketing implies broad compatibility, but the reality is very different. You only discover this after weeks of trial and error, following complex sync rituals and workarounds provided by Garmin support. By the time it becomes clear that your watch is effectively unsupported, the return window has passed. This feels like a buyer beware situation. If you do not already own one of Garmin’s newest watch models with explicit, updated firmware support for the Index Sleep Monitor, this device is largely pointless. Comfort alone does not justify the price when the core promise of training integration does not work as advertised. Bottom line: comfortable, but functionally unreliable and poorly disclosed compatibility. Do not waste your money unless you own Garmin’s very latest watch models.

É bem confortável pra dormir e não atrapalha o sono igual o relógio. Só a bateria que não aguenta mais que 3 dias. Valeu a pena ter comprado. Tenho todas as métricas em dia com ele

The idea behind this product makes sense. A dedicated sleep band so you don't have to wear your watch to bed. Unfortunately, the execution falls well short of what you'd expect from Garmin at this price point. The most frustrating issue is that it simply fails to detect sleep some nights. You can open the app in the morning and see a full night of heart rate data, proof the band was working and worn correctly, yet no sleep session is recorded. For a product whose entire purpose is sleep tracking, this is a fundamental failure. Syncing is the other persistent problem. Getting the band to talk to the app can take anywhere from 15 to 30 minutes, and sometimes it doesn't happen at all regardless of how many times you try. This is a daily frustration, not an occasional one. On top of this, the number of times I've had to remove and re-add the device entirely because it simply stops working is frankly unbelievable. This is not a minor bug; it's a recurring issue that suggests something is fundamentally wrong with how the device maintains its connection. Garmin clearly didn't put this through sufficient real-world testing before release. These aren't edge cases; they're core functions that don't work reliably. At this price, that's not acceptable. If you're already in the Garmin ecosystem and want to avoid wearing your watch to bed, the appeal is obvious. But until Garmin addresses these reliability issues properly, I can't recommend it.

⭐⭐⭐⭐⭐ Präzise Schlafanalyse ohne störendes Handgelenk-Gefühl Ich nutze den Garmin Index Sleep Monitor jetzt seit einiger Zeit in Kombination mit meiner Fenix 8 und bin absolut begeistert von der Genauigkeit und dem Tragekomfort. Das Problem: Ich trage meine Fenix 8 tagsüber extrem gerne, aber nachts hat sie mich am Handgelenk oft gestört, was paradoxerweise mein Schlaftracking verfälscht hat, weil ich unruhiger geschlafen habe. Die Lösung (Mein Setup): Ich lege die Uhr abends ab und ziehe den Sleep Monitor am Oberarm an. Das weiche Band spürt man nach zwei Minuten nicht mehr – kein Vergleich zu einer klobigen Sportuhr. Erkennung & Genauigkeit: Was mich am meisten überrascht hat, ist die Präzision im Vergleich zur reinen Pulsmessung am Handgelenk: Schlafphasen: Die Erkennung von Wachphasen und Tiefschlaf ist deutlich plausibler. Während die Uhr am Handgelenk oft "Wachzeiten" registriert hat, nur weil ich den Arm bewegt habe, filtert der Oberarm-Sensor das viel besser heraus. Nahtlose Integration: Sobald ich morgens die Garmin Connect App öffne, fließen die Daten vom Armband und der Fenix 8 perfekt zusammen. Mein Training Readiness Score und die Body Battery berücksichtigen die präzisen Nachtwerte des Monitors, als hätte ich die Uhr getragen. Zusatzwerte: Die Messung der Hauttemperatur und der Atemfrequenz liefert sehr konstante Werte, was mir hilft, meine Regeneration nach dem Training (ich trainiere viel) besser einzuschätzen. Fazit: Wer eine Fenix oder eine andere große Garmin-Uhr besitzt, aber nachts "frei" sein will, ohne auf die wertvollen Daten zu verzichten, findet hier die perfekte Ergänzung. Die Erkennung am Oberarm ist für mich das Goldstandard-Upgrade zum Handgelenk-Tracking.

this product is fantastic especially after the disappointment with sleep tracking using my Wellue BP smartwatch, its BP monitor is great BTW. I prefer wearing the Garmin arm cuff to bed than a watch anyway. The sleep chart is definitely accurate in terms of start and end time, I trust the sleep stage times as I can compare these to my Resmed CPAP machine metrics that flow into my myAir app. I'm following CBT-I (Cognitive Behavioral Therapy for Insomnia) as I'm currently sleeping only 4 to 5 hrs a night and want to extend this to 8 hrs. The sleep tracking is extremely helpful for this. Now I have to tell you why I dropped one star. The battery ran dry on me and I had to re-pair. You do this tapping the module 15 times. I must have had to repeat this 20 to 30 times before the module entered pairing mode to reconnect with my phone. I almost gave up their troubleshooting instructions are useless. I have sent Garmin support a feature request, give us a more deterministic way to pair. Initial pairing went smoothly so don't let your battery run dry.

Yo lo compré para tener métricos relacionados con mi sueño y así evaluar que tanto lo requiero para mis entrenamientos de sesiones largas al correr, así puedo ver si descanso suficientes y necesito más o si hay alguna alteración en mi cuerpo, además, la conexión es automática y rápida ya teniendo la aplicación garmin connect
