### 5/5 — My go to sleep app

*2026-06-19, version 1.24.4*

I’ve reviewed this before, and I still think it’s pretty good. One thing I wonder about though, in the statistics, what is depth of sleep? Not defined. Is there anyway I can get a definition for this?

### 1/5 — Not working

*2026-05-14, version 1.24.4*

This used to work well and now it isn’t tracking properly, turning off by itself and not counting total time consistently. Fix it

### 4/5 — Deutsche Version vermisst

*2025-12-09*

Die deutsche Version wäre super! Ansonsten gut!

### 3/5 — This is one of e  best sleep monitor out there BUT.

*2025-08-12, version 1.23.1*

EDIT:
tried 10 or more sleep apps and this is ok.  It allows for fairly useful charting, it has more control over sensitivity and chart color than any other app.
It is missing the ability to display hours of deep sleep, hours of mild sleep, and time awake.

### 5/5 — This is the best sleep monitor out there!

*2024-11-17*

I've tried 10 or more sleep apps and this is absolutely the best. It allows for the most useful charting, and has more control over sensitivity and chart color than any other app. All in all, this is the only one you will need if you want straight forward and concise data.  

This is so good I actually would buy it if that was an option.  Bear in mind I never use anything other than free apps, and not many of those.

### 5/5 — This is the best out

*2024-11-15*

I've tried 10 or more sleep amps and this is absolutely the best. It allows for the most useful charting, and has more control over sensitivity and and chart color than any other app.

### 1/5 — Deletes files too easily without explanation

*2024-11-07, version 1.23.1*

It has deleted files out of the blue with restore files button and im confused and dont know how to get my favourite recordings back. it now reads “no data recorded” and I am so so so sad please help me get my files back.

### 5/5 — Good app to monitor sleep

*2024-10-11, version 1.23.1*

So far so good! I’ve used the app for a month now and it helped me to understand how I sleep and helped me to plan a good sleep routine.
The bonus - it’s a free app! Use it ! I highly recommend it.

### 1/5 — it doesn’t work suddenly

*2023-11-08, version 1.22.7*

it doesn’t work suddenly.

### 1/5 — Why has the alarm stopped going off?

*2022-09-22, version 1.21.2*

I can’t sleep well if I can’t rely upon the alarm, waking me up on time or at all.
