GoodHabits 3.0 - A 66-day habit tracker with a grace day for real life

GoodHabits gives a single habit a 66-day run, based on University College London research that found a median of 66 days—not the 21-day myth everyone repeats. Miss a day, and you can still log it until the end of the next one, because the design assumes you're a person and not a streak. It's for people who want one thing to stick, not a dashboard of everything they're failing at.
