Hello,
The Cozmic Zoom app will be released on Android in a few days.
This is an educational science app that offers a journey into the universe, between the infinitely large and the infinitely small, while touching on notions of astronomy, cosmology, biology, and particle physics. See some screenshots here: http://www.tokata.fr
If you want to test the beta version, you'll get the final version when it's released.
To get the apk, please contact me at support at tokata dot f r or via PM.
Thanks!
Patrick
