On The Level

This application is a combination digital inclinometer and bubble level.  I wanted to make this app as simple and straightforward to use as their real life counterparts.

I also tried to make this as precise as the hardware will allow.  The measurements are calibrated to a hundredths of a degree accuracy.  Because of the fine level of precision and the uncertainty of the hardware its running on, the numerical display may not completely stop but bounce around a bit. A special filtering technique is used to keep the readings from getting too erratic. If you find that you are experiencing any problem with this app, please feel free to contact me. I’ll do my best to fix any problems that I can.

NEW in version 2.0 Support for larger display sizes. This application should work on Android devices with higher resolution displays like the Motorola Droid.

NEW in version 3.0 * Better support for different display resolutions. Tested on a Motorola Droid and the G1 phone.
Added the Dering Spirit level
Enhanced the graphics
Optimized the code to run more efficiently
Smoothed out the filtering for better accuracy

Some people have been having a hard time finding this app in the Android Market, so he is a link to it in the AndroLib. http://www.androlib.com/android.application.com-onthelevel-qzpm.aspx

    Really like this app!
    1. Would be very helpful if set the reference zero with a button click, then the display indicates angle displacement from this reference
    2. Would also be helpful if display correctly indicated angles greater than 90 degree from the reference
    3. Possible to indicate angles as negative to indicate direction from reference?

    Thanks heaps.

      Those are really good ideas. Let me look into how I can add them to the app. I’m planning on rewriting the level app, so this would be a good time to include new features.
