I have NEVER reviewed an app. In all my years as an iPhone user (10+) of all the apps I have downloaded (hundreds) I have never taken the time to leave a review and have always been so annoyed by the prompts “Enjoying our app? Rate us in the App Store.” Pole Detector App didn’t even prompt me to leave a review. I went back to my App Store JUST to say that this is the most efficient and accurate tool for detecting the N and S poles of a magnet. I’m experimenting with the placement of magnets along my water pipe to see what I can do to the structure of the water with a push pull dynamic created by strategically placing magnets along the pipe with a certain number of magnets making contact with the pipe from their north end and a certain number making contact from the south. This app has been a life saver and I have totally been able to manipulate the structure of the water that runs into my home. Thank you to whoever created this amazingness. Sending virtual hugs and high fives, secret handshakes and good vibes. Xoxo -m
