Mobile Phone Software

 

MicroSky

Sabine Plunderwww.upto.org

MicroSky is a free planetarium program for J2ME enabled mobile phones. It doesn't contain its own star maps (and as result, is only 20KB in size). Instead, it downloads them as needed from the SkyServer computer, via the internet. Therefore, a phone with a "pay by the kilobyte" internet connection is essential.

Platform: J2ME enabled mobile phones
