Accelerometer Toolbox Pro for Android
I'm a physics teacher, and this is a great free tool for real-time visualization of acceleration. I can attach my phone to a cart on a track with a rubber band for quick demonstrations or have multiple kids download the app and use it to test their ideas for an inquiry lab. It's also a great tool to take out on mini field trips, including driving in the car or going to a playground. Being able to download a csv file through Dropbox for graphing is a cool feature, but it'd be nice if the columns were labeled for student use. I'd also like to be able to start and stop the recording with my voice or a clap or something so that it doesn't record the time while I'm touching the phone. Could you add a numerical display in the corner? Any chance of a 2d mode?
Accurate and speedy sensing. Perfect use for a level.

I would add a share feature, but it's a great app for visualizing acc in one dimension.
