United StatesIdentify the poles of a magnet with the K&J Pole ID! This app lets you know which pole, north or south, is facing your phone. It will also tell you if a magnet is too close to your phone. The K&J Pole ID app, by K&J Magnetics, is a must have for anyone who uses magnets!
These apps are wrong
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.
United StatesReally good
I am actually impressed about how good this worked, super easy and fast.
United StatesBest pole identifier
The developer did an excellent job, I tried Many Similar apps , this one is the most Sensitive/accurate app out there. Thank you,
United StatesWorks great
Thank you for also labeling the poles with color. Green for the South Pole and red for the North Pole is perfect for magnet therapy identification.
United StatesDoes its one job well
App has just one job — identify poles of a magnet. Works just as advertised. No need to get phone close to magnet. In my tests it identified pole from a foot away (will vary with magnet strength I’m sure)
United StatesWorks perfectly!
This simple, easy to use app does exactly what it claims. It’s a great tool for anyone who needs to determine magnet polarity.
United StatesIt works like a charm!
Easily identified north and south poles on magnets. It makes it easy to determine which direction the magnets are facing for craft projects to ensure that it is all aligned identically. Will use it again to check magnet polarity! Minor issue: The terms and conditions required me to scroll down to the bottom of the toc before it let me select accept.
