KJ Pole ID

At first, it seems really good. i used it to label my magnet, then when i went to double check, it gave the opposite end instead. i then realized that if u gently turn the magnet over close to the sensor, it wont identify the polarity change and will instead keep what it originally showed. for example, u put the "south" end close to the sensor, then gently turn it over so that the "north" end is close to the center, it will still read it as the south end.

Easily identify poles even with small 3x2mm magnets.

I’ve set a few magnets magnets using a the sting method. Each one a different size and different location. Nothing like Mother Nature telling you what your polarity is based on polarities attracting principle. I even went as far as to confirm it with my compass. However when I put the phone to those polarities on the magnet already labeled then it tells me the complete opposite. I think the algorithm on this is wrong or maybe it works with certain phones and not others.
