So I made my first app, an full-fledged magnetic field sensor aka metal detector. It's nothing too spectacular, but I thought you guys might find it useful. You might wonder what you can do with this app, except the obvious metal detecting business. Features: -Displays the field strength in microtesla, milligauss or in gamma. -Works through walls! Detect hidden electrical wires. -Export the data to a CSV file -Vibration alarm -Free and No Ads -Option to force screen on to prevent screen from closing -A historical chart -Optimized for Ice Cream Sandwich/Holo theme -Full-fledged preferences menu to tweak the app to your needs! -Works on Gingerbread and up! Tablet mode is coming as well. The app looks great on ICS, with a native feel to it. It's also free of bloat like Payware or ads, completely free! But there are already a ton of metal finders on Play, you might say. But a lot of them carry an outdated interface, or just look bad, or full of ads. There are also some great comparable apps out there, but a little competition can't hurt . For download/screenshots, check it out at Google Play Here! Happy metal hunting!
