Gyroscope lets me visualize my days and months with cool graphs and maps. It also integrates with Fitbit, MyFitnessPal, and Strava. Also tracks my music and productivity on my MacBook. Pretty cool because at the end of the month, I can see where I've been and how much time I've spent running, working at coffee-shops, commuting, etc. I really enjoy my Pro subscription because the developers behind it are always updating/fixing the app and talking to subs via a Facebook group.
