HabitDelta

HabitDelta is a mobile + web habit tracker focused on temporal analytics: it shows which specific changes in your routine (sleep, location, meeting load, travel, weekends, seasonality) correlate with habit success or failure over time. Instead of just counting streaks, it builds a timeline of “deltas” (what changed since your last good week) and highlights the top 3 likely drivers behind your drop-offs. Users log habits in seconds, optionally connect Apple Health/Google Fit and calendar data, and get weekly reports with simple, testable experiments (e.g., “On days with <6.5h sleep, your workout completion drops 42%—move it to lunch or reduce intensity”). It’s brutally pragmatic: it won’t promise transformation, it will help you run small behavior experiments and track whether they worked. Exportable charts make it useful for coaches and therapists too.
