### 3/5 — there are other options that are so much better. 😟

*2025-02-16*

there are other options that are so much better. 😟

### 1/5 — Can’t reset the app to restart tracking

*2024-08-09*

You will be disappointed if you own the app and they have not updated it for 2 years!!’

### 3/5 — Accurate but too sensitive

*2022-02-05*

I was excited to try this in my Yak-52 during formation aerobatics. Unfortunately, just the vibration of the engine made the needle jump to +2/-2. If there was any way to dampen this, it would act much more like a aviation real G-meter. Otherwise it appeared to match the max readings on my panel mounted g-meter.

### 2/5 — Needs some work

*2021-09-09*

The GPS groundspeed is very inaccurate, it was reading 32kts while I was travelling at approx 60kts. 

Also, this app doesn’t show any negative G due to hardware limitations (iPhone 11 Pro).

**Developer response:** Hi, can you give us some more information on your flight conditions please? The gps derived ground speed is usually very accurate. Many thanks.
