I'm using IRT Calendar. It's not a free app and though it works.. I'm not certain it's worth the $. I purchased the calendar way back when only because the developer promised to add an option to check off agenda events that were completed as well as marking them paid in full which is something I longed for. He must still be working on the option lol. It is a nice calendar however.. has multiple views, syncs with google, etc. If anyone finds a calendar that allows one to check off agenda items... as well as mark if you were compensated for completing the agenda task.. I'm interested.
