One of the perks of the accelerometer in the BlackBerry PlayBook is leveling apps. Ilabelu let us know in the comments about the RIDGID Digital Bubble Level for the BlackBerry PlayBook. The app actually performs well as a level and better yet is totally free.

While there have been a few levels for the BlackBerry Torch I think Bubble Level Pro is the best BlackBerry level I have seen yet for the PlayBook. Stephen Lake Design has released Bubble Level Pro which is a torpedo bubble/spirit level app for the PlayBook. Its a nice and simple app that is very useful when hanging frames or trying to level your projects.
You can pick up Bubble Level Pro in App World for a very reasonable $0.99
