### 5/5 — 磁石極性が一目でわかる

*2020-10-02, version 140819*

磁石を埋設した際に磁極確認するのに非常に便利なアプリです。大変重宝しています。
Androidでは「磁石S極／N極磁極判定アプリ」という名称です。

### 3/5 — 極性が

*2019-02-05, version 140819*

便利だけど極性が逆に出ます。
それがなんとも使い辛い！

### 5/5 — Great app!

*2018-10-01*

It actually works! No adds! Love it!

### 5/5 — Works GREAT!

*2017-07-10*

I love the app! It helped me confirm my magnet tester. And both works great ^_^ it tells you which pole of the magnet you have while facing the screen :)

### 4/5 — すごいですね

*2016-06-02, version 140819*

ただ詳しい説明がされていないので詳細に教えていただきたいなと思いました
N極S極を調べる機能に関してはわかりやすかったのですが、表示されるのは画面に接近させた面の磁極なんですかね？
ガウスメーター機能はあまりわかりませんでした

### 2/5 — 単位表示

*2014-10-14, version 140819*

SかNかの、表示がされないので本来知りたい事が解らなく困惑する。解ればかなり楽しそうだし、役立ちそう

### 5/5 — suggestion

*2013-10-18*

hey i have a question whats the max safe tesla field for the iphone?
