*Inspired by the Never Miss Twice philosophy from Atomic Habits. Build consistency without chasing perfection. Most habit apps expect you to be perfect. Miss a day and your streak is gone. Two Hearts is built around a simpler idea: Don't miss twice. You start with two hearts. Miss a day and lose one. Miss again before getting back on track and you break your streak. Life happens. The goal isn't perfection—it's returning. Features The Two Hearts System: A gentler alternative to traditional streaks Designed for real life, not perfect days Focus on consistency over guilt Zoom from Day to Year: Track your progress across weekly, monthly, and yearly views See patterns instead of obsessing over individual days Watch consistency compound over time Home Screen Widgets: Check your status without opening the app See remaining hearts, streaks, and progress at a glance Quick reminders to stay on track 100% Private: No accounts No sign-ups No cloud sync No data collection Everything stays on your device. One Habit. One Focus. No endless habit lists No complicated setup No productivity theater Choose what matters most and show up consistently. Why Two Hearts? Most habit trackers are designed around streaks. Two Hearts is designed around recovery. Because success isn't never missing. It's coming back before a missed day becomes a missed week.
