The REM and DEEP sleep needs some fine tunes. **Developer response:** Hi JMRBR, thank you for the detailed feedback. You were right, there was a critical bug where sleep data before midnight was being cut off, which is why it always showed sleep starting around 11:45 PM regardless of your actual bedtime. We've fixed this in the latest update, along with improved REM and Deep sleep thresholds that better reflect real-world Apple Watch data. Please update the app and let us know if things look better now. We really appreciate you taking the time to report this. ### 2/5 — Great design, wildly inaccurate *2025-12-23* This is a really good looking app. It only seems to be analyzing REM and Deep sleep stages (there’s no display of Core and waking/interruptions), but I’ve got to think they’ve got a point of view on that. But the app seems to think I get nearly double the sleep hours that I actually do, and the horizontal sleep chart extends to the right past the bounds of the chart, past the edge of the screen, right off the phone and into space, I guess. (Sadly, my phone is a generation behind and I don’t have the external holographic display feature to show the rest of the chart lol) I’m sure that’s just a bug in the app (though a kinda important one; for example, I had a late night last night and only got 4 hours and 55 min of sleep, not the 9 hours and 28 min the app is telling me I did - I wish!). It’s hard to really evaluate the app so far because of that, but once it’s fixed I’ll come back and update this (without the sarcasm). **Developer response:** Thanks for trying the app and for the honest review! We really appreciate you taking the time to point out the issues, especially with the sleep duration and the chart going off the screen. We're already working on a fix for that, as well as improvements to how sleep stages and interruptions are displayed. Once it's updated, we’ll let you know here so you can give it another shot. Thanks again for helping us make the app better. ### 3/5 — Great design, has growing to do *2026-01-27* This is a really good-looking app. My initial interaction with it was hampered by a display bug (that’s now fixed), so I’m updating my review from 2 stars to 3 and taking a fresh look. The color choices are difficult to discern for colorblind eyes like mine: for example, in the Sleep Score section, REM and Deep bars look like the same color to me. In the chart for the night’s sleep, I don’t understand what the bar heights are communicating (and the color choices for Deep and Core are really hard for me to tell apart). There are some natural navigation gestures that I keep trying to do but aren’t here, like swiping to navigate days, and navigation between single metric and multi-metric when tapping on elements on the screen. I think this app has good potential, and I’m interested to see where it goes. As it sits it still feels like it hasn’t quite reached 1.0 yet. (A concern: the app’s privacy label says it collects no data, but the AI Coach says it has 30 days on my sleep data already loaded. Is that using on-device AI, or using AI on a server, and if so what? Thats a really important distinction to call out, and if it’s using server-based AI, some discussion in the app about how my data is kept private seems important.) **Developer response:** Thanks for trying the app and for the honest review!

Thanks again for helping us make the app better. ### 5/5 — After update *2026-03-15* After the update the app is working very well. Good job. **Developer response:** Hi JMRBR, thank you so much for the great review! We are thrilled to hear that the app is working perfectly for you after the update. Have a great day! ### 5/5 — Great works *2026-02-06* This app works very well, better than most sleep apps from App Store, the accuracy is very good. I am using the FREE app, because I don’t know if the additional IA coaching will works. Great job. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
