Played with this and it seems to work!!
I know it says you need a special type of device, but I plugged in my headphones and used the mic and placed it behind my watch.... I Had a pretty good idea if I’m tracking it every day how fast or slow my watch runs. This app pretty much Verified the exact deviation that I was calculating myself simply by tracking it on a day today basis. I was also amazed by the magnetism detection... at first I thought “no way” but then I held one of my headphones up to the back is my phone (magnet from the speaker in it should detect a difference) and the thing went nuts! I don’t know how useful it is for long term tracking or actual data collection, but it seems pretty accurate to me. Better than paying for another app! Give it a try!! It’s free!
Don't even think about DLing this app unless you have $600 for the sensor it NEEDS, to make it work. Yes that's right, $6-HUNDRED--DOLLARS!!!!!!!! Ho-LEE-$&#%. Where's the minus stars rating tab?!?
