ThumbCal is a customizable fingerfriendly calendar application for Windows Mobile Pocket PC’s. You do not need your stylus anymore to navigate through months and years, tasks and appointments or to quickly create or delete them.

ThumbCal is free for personal use.

Changes:

– changed the date format for restricing appointments and tasks in hope that less users will have problems with not showing appointments
– many minor bug fixes
– faster animations
– tap on upper right corner (if not with windows taskbar) minimizes the app (in 0.4 it closed the app)
– contextmenu now disappears when the user taps outside its area, therefore the “cancel” option doesn’t exist anymore
… other things that slipped my mind …
