### 1/5 — Bogus

*2026-01-25, version 1.1.0.50*

Won't restore my purchase

### 1/5 — Minutes are displayed in a tiny size

*2025-10-18, version 1.1.0.39*

I feel cheated. I purchased this app based on advertised pictures of how the alarm screen looked like but in reality, the minutes are displayed so tiny I need a magnifying glasses to see them.

### 1/5 — AD BOMBED!!!

*2025-09-05*

Absolute junk!  Tried to give this a try at least for a day before committing to a subscription.  I was literally bombarded with ads, to the point that I couldn’t do anything with it.  Couldn’t even purchase a subscription at that point if I wanted to because the ads just kept cycling one right after the other.

### 1/5 — Wastes battery life

*2025-08-24, version 1.1.0.31*

First of all, you better make sure that the battery is 100% before using since Screen has to stay on all night long.And that you had better not grab the phone to do anything, because if you forget to leave the app open and on screen, then the alarm will ring for a very short period of time and then turn itself off.

### 1/5 — I

*2025-08-04, version 1.1.0.29*

The alarm never went off I set 3 of turn
