### 2/5 — Otherwise great app ruined by scam ads

*2026-08-01, version 9.13.2*

Just a constant barrage of ads claiming I’ve been hacked or my software is expired. More than one ad every 30 seconds. Seems like a nice app but it’s basically unusable.

### 1/5 — Spammy

*2026-06-06, version 9.13.1*

### 3/5 — its just ok

*2026-04-22, version 9.12.3*

Its a great locator, but hard to use & navigate - a users guide would be useful

### 4/5 — This is funny

*2026-03-16, version 9.11.4*

I got this app mixed up with a school app i needed but currently i am learning about longitude and latitude which is pretty cool but this could actually help

### 1/5 — Not intuitive

*2026-03-08, version 9.11.4*

Took me 30 minutes to get points on a map.   Never did get my distance or azimuth.

### 1/5 — Nicht zu gebrauchen

*2026-01-25*

Handling absolut umständlich,
Anleitung völlig unverständlich.
Gleich gelöscht.

### 1/5 — Not intuitive

*2026-01-22, version 9.11.3*

Maybe this is for NASA and Mensa?

### 5/5 — Extra good

*2026-01-21, version 9.11.3*

Morr good than good, good again, another good…
