★★★★★ "This app is great for a few features which aren't available in most apps. However, the amount of ads is frustrating, considering the base app could be vibe coded in 20 minutes, and there's no way there's an expensive upkeep for this app." - Aries Powvalla

★★★★ Ed Cyr 6/27/2026 v20240808
Atrocious, I had this bug where i couldn't access the app and couldn't stop the alarm. I couldn't go in my notification and couldn't remove the sound. I had to uninstall it in my settings because it wasn't stopping no matter what... i was turning crazy.
★★★★ Mohammad Khademi 6/24/2026 v20230124
you have to pay for everything
★★★★ John Swift 6/23/2026 v20260616
How do I get my other account back please 🤔 I've used it for nearly 10 years on my old Gmail at swiftys93@ and now I've changed my my email and phone number it wont let me get my full account back and records please 🤞🏻🙏🏻
★★★★ Matt Davis 6/23/2026 v20260616
Couldn't shut the alarm off, even after a restart it kept going off with a different alarm sound.
★★★★ Afifa Shamsad 6/20/2026 v20260616
app helps me, but I want to make my bed cooler because Studies consistently show that cooler ambient temperatures lead to more stable, uninterrupted periods of REM (dreaming) and slow-wave (deep) sleep. In contrast, being too warm causes micro-awakenings-those annoying moments where you briefly wake up just to adjust the blankets.
★★★★ Adam Rabczuk 6/19/2026 v20260616
How do I disable stupid emojis and confetti from wake up CAPTCHA?
★★★★ Simone Fittabile 6/18/2026 v20260616
double 6.16.2006 update from PlayStore with concurrent play services side load kernel updates .. fishy dexopt management policies on dalvik machine and ART security from Telecom Italia CDN. (and Google TLS certs of course)
★★★★ Julio Felipe Chang Tokumoto 6/16/2026 v20260609
When are you going to let us set the default alarm to silent?
★★★★ Felix Boxhammer 6/14/2026 v20260609
update reset all my settings INCLUDING my running alarms, inexcusable for an alarm app
★★★★ Scott Pain 6/9/2026 v20260606
Really good until recently. Now it seems to be AI emojis everywhere. I don't need a crying face if I typo a maths question...
★★★★ John G 6/6/2026 v20260530
Sleep analysis (cycles) doesn't work completely, and it's a huge part of the app, even morning alarm should be based on cycles - so I don't think anything works reliable in my case. I've requested a refund via email and I do want it
★★★★ Le “DaggerWrath” Dagz 6/4/2026 v20260530
the fkn ads man. one day somethings normal one day its premium. i dont mind watchig ads to unlock things for a day. or general ads for advanced features. but now having to pay to edit a nights sleep? because the app recorded it wrong? now my entire averge is fooked. a lot of us dont mind ads. but be consistent. literally thrown out 7 other trackig app metrifs and my google account. disabled people spend enough money, let us fon try something for free so we know we are investing.
★★★★ Guy Wellman 6/3/2026 v5.32
won't work on OnePlus Watch 3... Tried twice! Either that or it's so complicated that I missed something in set up. Won't be renewing that subscription.
★★★★ Tallb 6/2/2026 v20260526
Been a user for 10 years, lately some free features like smart wakeup turned premium . Thats not a way to get my money , very disappointed , uninstalled.
★★★★ Ashley Hulme 6/2/2026 v20260526
This used to be great. But the recent garmin updates have stopped tracking working
★★★★ Barrett Frazier 6/2/2026 v20260530
no longer accepting correct answers. can't disable wake up check which I didn't turn on.
★★★★ James Butcher 5/31/2026 v20260526
avoid terrible won't conect to watch won't pair and does not track sleep do not subscribe its a scam
★★★★★ Agent13Cookie 6/26/2026 v20260616
This is the 10th time my alarm did not go off and caused me to be an hour late to work. I have been using this app for nearly 8 years and it has been a mixed experience but now its wholly unreliable even with the current updates and following the instructions on their website to keep the app working properly. I will be switching to a different one since its affecting my job and I don't want to lose sleep being anxious every night wondering if it will go off.
★★★★★ Heather Harcus 6/24/2026 v20260616
The alarms do not sound at the volume I have set for them. I have my alarms in this app set for the highest volume as I am a very deep sleeper. If I have my phone's master volume set lower then this alarm will start at the lower volume and I cannot hear it. Sometimes I want to listen to something quiet while I fall asleep but this makes this alarm app completely ineffective. I do not have this issue with other alarms or apps. Is there a way to set this app to override the phone's master volume?
★★★★★ Freddy 6/13/2026 v20260609
After growing frustrated about Sleep² not addressing any of their several usability issues for months, I decided to give the competition a try. Quite a letdown, I have to say, after realizing this can't even derive sleep phases from heart rate data only. Movement sensor just doesn't work for me, as I always have my partner and/or our 2-year old kid in bed with me (so far the app hasn't even managed to produce a phase graph from the data it's getting). Quitting the experiment after a few days.

I fly airlines. This app is more cluttered than my cockpit
