TRANSLATIONS:
PrediSat is ready for translations! Google Translate isn't quite good enough (I've tried), so I need human translators.
If you would like to help, translation is crowdsourced at http://getlocalization.com/predisat
If for any reason you can't or don't want to use Get Localization, you can always email me.

PROBLEMS OR SUGGESTIONS:
Please email me or submit the problem or suggestion at http://tracker.pilot51.com. Usually Google Play comments or even Android crash reports don't tell me everything I need to know to fix it and there is no way for me to reply to either to ask for more details.
