Default [APP][2.1+] Metal Sniffer - Holo-looking tool

Update2: New version 0.5.0 out, should support Android 2.1 and up now, along with a few extra features. More info at: http://forum.xda-developers.com/show...5&postcount=78

Update: Featured on Redmondpie!

So I made my first app, an magnetic field sensor (aka metal detector). It's nothing too spectacular, but I thought you guys might find it useful.

But there are already a ton of metal finders on Play, you might say. Most similar apps on Play right now looks like they're made for Android 1.6 or ads-packed, so why not release my own take on it without all the gimmicks.

There are also some great comparable apps out there, but a little competition can't hurt . It also works through walls, so I guess you can use it to detect hidden electrical wires.

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.
-Export the data to a CSV file, do anything with it
-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
-Works on Gingerbread and up. (version 0.5.0 : Android 2.1 and up)

The app looks great on ICS, with a native feel to it. It's also free of bloat like Payware or ads, completely free!

For download/screenshots, check it out at Google Play Here!

Happy metal hunting! Would appreciate any constructive comments or crashes that you may have A rating would be awesome as well.
