nibbit: Habit Tracker

nibbit is a habit tracker built on the science of how habits actually form — one small bite at a time. Most habit apps count streaks and ring bells at you. nibbit goes deeper — with implementation intentions that anchor new behaviors to existing routines, smart reminders that stop bothering you once you've hit your target, and milestone celebrations at the research-backed checkpoints where habits start to stick. SMART REMINDERS Set multiple reminders per habit, on specific days. When you've completed your daily or weekly target, nibbit silences the remaining reminders automatically — no noise, no nagging. GROUNDED IN HABIT SCIENCE Each habit has a cue field: write "After I pour my morning coffee..." to build an implementation intention — proven to accelerate habit formation. nibbit celebrates milestones at 7, 21, 30, and 66 days — the point where research shows most habits become automatic. A grace period forgives the occasional miss, and skips keep a planned day off from breaking a streak. FLEXIBLE SCHEDULING Daily habits. Specific days of the week. Every other day, or every N days. X times per week or month. Multiple completions per day (drink water 8×). And "at most" habits for the things you want less of — limit coffee to 2 a day and record a "none" day as a win. GROUPS Organize habits into routines like Morning or Wind-down, reorder them the way you do them, and read a weekly digest of how the week went. SEE YOUR REAL PATTERNS A day-of-week heatmap shows when you're most consistent, and the activity calendar lets you tap any recent day to log or correct past completions. ON YOUR HOME SCREEN AND YOUR WRIST Home screen and lock screen widgets show today's habits at a glance. The Apple Watch app and complications keep today's progress on your wrist.
