### 1/5 — Attempts to install malware on the phone

*2026-07-25, version 2.0*

This app works for about 5 seconds then locks you into game adds then pressing any button brings up a fake malware alert that tries to get you to download malware. VERY poor. I thought the App Store was supposed to stop this sort of nonsense.

### 1/5 — Sus AF

*2026-07-16, version 2.0*

On what planet is it OK for a device using the gyroscope, to touch the audio subsystem?

### 1/5 — Pub

*2026-05-25*

Impossible à utiliser avec les pubs qui envahissent l’écran

### 1/5 — Hacker Software

*2026-05-17, version 2.0*

App will never close.  Open all the time.

### 5/5 — Level

*2026-05-07*

Works good

### 1/5 — Not useable

*2026-02-16, version 2.0*

Constantly flooded with ads to the point where it is not useable. For something that should be a quick check, this app makes the whole process impossible.   I’d pay 30cent for a tool like this. But if I’m paying at all, then I’ll head to the hardware store and get a proper one.

### 2/5 — Just adverts/game

*2026-02-13, version 2.0*

Used to be a useful app but now just shows a game that I cannot get rid of- useless

### 5/5 — No ads very good

*2026-01-22, version 2.0*

Very helpful

### 1/5 — Impossível usar

*2025-10-17*

Tem tantas propagandas que não podem ser fechadas que não é possível se quer testar

### 1/5 — First start brings me to a game screen !?!

*2025-10-04, version 2.0*

Just annoying - before I was able to do anything meaningful with it, it popped up a mobile game > immediately deleted it.
Would be willing to pay for a good tool but this ist just waste of time.
