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. ### 5/5 — Really good *2020-09-22* I am actually impressed about how good this worked, super easy and fast. ### 5/5 — Works *2020-08-30* Free, easy to use, no ads, works as intended. ### 5/5 — Best pole identifier *2020-01-07* The developer did an excellent job, I tried Many Similar apps , this one is the most Sensitive/accurate app out there. Thank you, ### 5/5 — Simple - it works *2019-12-14, version 1.0.2* Nothing more to add x ### 4/5 — Great app *2019-08-12, version 1.0.1* Great app needs an update for iPhone XS as the sender has moved ## Frequently asked questions about KJ Pole ID ### What is KJ Pole ID used for?
