A tour of what you actually use.

01

Dashboard that celebrates progress

Open the app and see your streak, weekly average, and a Smart Observation that surfaces the pattern you didn't notice. Weekly challenges turn tracking into a (weirdly fun) habit.

  • Streak + total + weekly average at a glance
  • Achievement badges for consistency
  • AI-powered Smart Observations (on-device)
