Build an app based on the 'habit stacking' method from James Clear's Atomic Habits. Users chain new habits to existing ones: 'After I pour my morning coffee, I will meditate for 5 minutes.' Include a visual routine builder with drag-and-drop habit ordering, timed sequence mode that guides users through their stack step by step, completion tracking, and streak celebrations. Habit apps are a massive category with high engagement and willingness to pay.
🚀 First Step
Create a Flutter app with a 'Build Your Stack' screen where users add habits, order them by drag-and-drop, and assign each to an existing trigger habit (morning coffee, after lunch, before bed, etc.).
  • Focus entirely on the habit stacking methodology — generic habit trackers are commoditized, but a tool built around a specific, proven methodology attracts fans of Atomic Habits searching for exactly this
  • Include a 'Guided Stack' mode that reads each habit aloud and starts a timer, moving through the stack hands-free — the audio guidance feature is unique and podcast-friendly for morning routines
  • Price at a one-time $4.99 with no subscription — habit app users have subscription fatigue and a fair one-time price drives more purchases than a $3.99/month subscription
