This app is very exciting for children in the classroom. It provides live data in a very visual form that engages the children. Rather install this on all of the iPads - i tend to just wirelessly present and hand my iPad to the children to explore.
The whole class can watch. We screen shot the data and share through the Showbie app. At a basic level you could use Pic collage to sequence the data, fast, faster, fastest etc or use something more sophisticated like Numbers or charts in Keynote. You can't export the data from the app. It also has a cute AR option where you can point the device into the sky to track planes above you!
