On The Level app

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.

NEW in version 4.0    * Support for Froyo  
                                    Support for the Dell Streak

                                    Slope gauge that displays percentage of slope and rise/ run in english and metric units
                                    Complete rewrite, now this app is more Android-like in operation
                                    Newer, updated graphics

NEW in version 4.01    Minor UI fix involving Two Step Calibration in the inclinometer

NEW in version 4.02    Added option to install app to the SD card (I've tested this in an Android emulator and it seems to work great!)

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

This is the first screen that appears when you launch the application.  Lay your phone along any of it edges on the surface to be measured.  The indicator will display the current 'up' angle.

Pressing the center of the dial will flip the numbers between 0 and 90 degrees.

Pressing the lock button in the upper right corner will freeze the display for easier reading.  A red circle appears over the display to indicate that the display is locked.  Press the lock button again to unlock the display.  The center dial switch is still functional and will switch the locked display from 0 to 90 degrees.






THE DERING SPIRIT LEVEL SCREEN


This screen was added by the request of a user. 

Press the center of the spirit level display to change the orientation of the level in 45 degree increments.

Pressing the lock button will change the background red, and freeze the current measurement.  Press the lock button again to unlock.  While locked, you can still switch between modes and orientations.

This level is limited to displaying values in the range of -30 to 30 degrees.

Pressing the lock button in the upper right corner will freeze the display for easier reading.  A red circle appears over the display to indicate that the display is locked.  Press the lock button again to unlock the display.






THE SLOPE GAUGE


This screen was added by the request of one of our users.

Please note that values over 1000% are filtered out.

Pressing the center of the display will toggle between english and metric measurements.
