My bad, I thought the primary selling point was that it would would hook into the services you already use for tracking your commitment (Strava, GitHub, etc.). I am aware that you can manually enter some data but I didn't think there was any way to validate the data that you enter and I didn't think it was their focus.

Anyway, sorry for the misrepresentation. I will update my comment above to be more accurate.
