Good grief, I'm impressed - this is PRECISELY what I've needed all along, an app that lets me record where I am and what I'm doing on my calendar, with the lovely bonus of throwing notes etc. in as well. THANK YOU, this ROCKS!
Needs a widget and statistics (at least daily summary). UPDATE 20150915: still needs improvements!
Pretty cool... I like that it lets you have multiple tasks running at the same time...
SUPREME GREAT LOGGER
Add a feature of recording to multiple calendars.
