This app is actually a pretty cool and interesting game. Students use one or more gears to 'power' a blue gear already on the screen. With 200 levels, it obviously gets more difficult as the game progresses. Visual-spatial learners will especially enjoy this app.
While it's a worthwhile app to have installed, skip it if the price tag seems too steep for your needs.
