Works like a CHARM!

This app definitely deserves a 5 Star rating. It is so sensitive that even if the watch falls under manufacturing parameters it will still pick up the magnetism exhibited by the timepieces. Easy to set up and configure, but once configured can be used to measure not only watches but also the places where the watches are kept. Need to make sure where you store the watches is not the source of any magnetism. RECOMMEND HIGHLY!


Detector of ferrous metal, and maybe magnetized watches.

Firstly, the app works nicely for what it is. But it should be known that the compass chip in the iPhone will, like any compass, be affected by ANY ferrous metal. Whether that ferrous metal object is magnetized or not. So if the app tells you that your mechanical watch is "magnetized", you are more than likely getting attraction to a ferrous part (the strap springbar or clasp are likely culprits). If no strap, then the mainspring or small screws & parts may be enough to pull the compass, even if not magnetized. If you're demagnetizing over & over and still getting a "magnetized" reading, this is why. Perhaps watch the strength level, if it drops, you may have removed some magnetic contamination, but you'll always get "some" reading from clean steel, if present. All similar apps like this work this way, so not a problem, so long as you are aware.

Definitely works

I just tested this with two Omega Speedmasters; one is magnetized and one is not. The non-magnetized watch does briefly say magnetism is detected if you place it very precisely, but the magnetized watch clearly shows magnetism detected when placed anywhere in the ballpark of the compass. The difference is very easy to recognize.
