### 4/5 — Data Recording ??

*2022-11-06*

This App appeared to work very well, until I tried recording the data … After stopping record, there was no option to save a file, and the App crashed.

I have repeated this exercise with the same result.

Note: __  I am using a 9.7” iPad Pro

The VERY good news, however, is that I have downloaded the ‘suite’ which works fine … Thank You for a great resource.

### 5/5 — No ads! Works great!

*2026-07-14*

All the features I wanted in a magnetometer app. I tried another one but it had a lot of ads.

### 5/5 — So cool!!

*2026-02-14*

I love how the creator(s) are taking advantage of sensors that are already in the phone to make this huge variety of tools that work surprisingly well. Great job devs

### 5/5 — Best free magnetometer

*2018-04-02*

I’ve tried dozens of apps and was even tempted to purchase some but this is exactly what I was looking for. I use this app to make sure my electric blanket is working because the cord sometimes disconnects. Holding my phone close to the sheets slows a clear indication it is working.
