### 5/5 — The greatest thing to ever come out of the App Store

*2025-03-16*

Lost my precious child, but with this masterpiece of a magnetometer, I was able to retrieve it again.

### 3/5 — Worth checking out!

*2024-09-02*

To my surprise it actually works!…It’s far from working perfectly… but it can detect if something is metal or magnetic!  Not the most accurate but it does work

**Developer response:** Hi,

Thanks for sharing your honest feedback! I really appreciate it.

Due to hardware limitations, Magnetometer can’t be 100% accurate, and should not be used in any critical environment. It should be reasonably accurate for most entertainment purposes.

Wishing all the best!

### 5/5 — Works well

*2024-01-20*

At first I thought it didn’t work but to make it work put your selfie camera towards the metal.

### 5/5 — Work well to check watch magnetism.

*2023-12-07*

Work in term of magnet fields detection. I will not pronounce me regarding the value mesured, cause i can’t compare with real Gauss meter. But to detect magnetism on watch, it work. On IPAD and Iphone. Be carefull, the area to detect on iphone are on the top, the area on Ipad are at bottom when Ipad are horizontal.

**Developer response:** Hi,

Thank you very much for the positive review, it means the world to me!

I cannot validate the scientific accuracy of the built-in magnetometer. The data is provided by the one inside your device, which is out of my control for any tuning or accuracy improvements. 

Thank you for your understanding!

### 5/5 — It’s perfect

*2023-11-05*

Simple, free, it’s everything everything you’d want.

**Developer response:** Hi,

Thank you so much for the positive review! I’m glad you like it!

### 5/5 — Ajudou a resolver um problemão

*2023-05-07*

Nossa gatinha achou e estava brincando com um chaveiro que tinha um imã. Mas o imã se perdeu. Usamos o App na gatinha, passando o celular pelo abdômen dela, não identificou nada. Achamos que tivesse comido, vasculhamos a casa toda com o App e ele ajudou a encontrar o imã sob o sofá! Obrigado!

**Developer response:** Hi,

I’m glad you have found Magnetometer useful! 

If there’s ever an issue, don’t hesitate to reach out.

Thanks for using Magnetometer!
