I like the looks of this, can I import all of my current time data somehow? I totally want to dig into the code when I have more time this summer because I've been wanting this exact tool. Thanks for posting this!
Not OP, but I have a lot of tasks in Google Tasks, and goals & journaling etc. in Google Calendars. Being able to import, or (even better) sync with these would be a real winner for me.
I fully agree, and have the same need, in fact as I use gCal/goals frequently (which conveniently integrate with gFit), and end up having to double-mark currently.
It seems like Google's APIs for tasks/keep/goals, etc are in flux right now, which is not ideal, but I will be looking into an integration to remove that redundancy.
