### 1/5 — Scam

*2025-06-28*

App doesn’t work

### 1/5 — だめです

*2025-01-20*

動きません

### 1/5 — Magnetometre

*2024-02-20*

Ne fonctionne pas sur iPhone 14

### 5/5 — Works well on iPhone 14 Pro

*2023-07-25*

Also indicates the direction of the magnet or magnetic force.

### 5/5 — 很有趣

*2022-08-05*

体验不错

### 2/5 — Meh

*2022-06-25*

The only real use for this is to help understand how quickly the magnet strength drops off when the magnet is moved away from the detector.  A simple but good quality mechanical navigation compass is more sensitive. 

The direction indicator doesn’t work because it reacts dramatically to changes in magnetic pole orientation.

### 1/5 — DOESN'T WORK

*2022-06-24*

This app doesn't work and is not worth a second look!

### 1/5 — Does not work at all on iPhone SE 2020 iOS 15.5

*2022-06-22*

As others have reported this App does not measure anything as the magnetic field strength sits firmly on zero.

I even passed it over my magnetic gimbal clamp and some transformers.

Ironically even the “rate on the App Store”, in the Apps own settings screen is broken and does nothing!

Luckily for me this App appeared on my free App for the day App.

Note to Developer: Location Services and all necessary settings in the iOS settings App were fine with full permissions given to your App where available. The App just does not work on iPhones as others have reported.

### 2/5 — Location required.

*2022-06-21*

Other apps don’t need it to work.

**Developer response:** System magnetometer not working without enabled locating services in iOS. But application not used location services.

### 1/5 — Not working

*2022-06-06*

Doesn’t work on my iPhone
