If you haven’t downloaded the “Apps Gone Free” app to your iPad/iPhone, I strongly recommend it. My rules are simple:
1. I never download games unless there is an educational purpose to it.
2. If in doubt, I download. Deleting a free app can be easily deleted.
One of the featured apps from yesterday is a Tangram app. It reinforces spacial awareness. I downloaded it this morning and it was still free. Go get it!
