HabitForge — habit-building backed by behaviour science
HabitForge is a free habit-tracking app that visualises habit strength as a rope getting woven thread by thread. It models the cue-routine-reward loop from Charles Duhigg's research, treats keystone habits as priority anchors, and stays resilient to occasional missed days instead of resetting your streak to zero.
- Visible habit strength — your progress shows up as a thickening rope, not just a streak count.
- Design habits around cues, routines, and rewards (the habit loop).
- Keystone habits flagged so you double-down on the ones that change everything else.
- Free on web, Android, and iOS. No paid tiers, no upsell.
- Cross-device sync via Firebase — sign in once, your habits follow you.
