Features
A tracker that does the statistics for you
Logging is the easy part. Metricky's job is the other half: telling you which of the things you track actually move the outcomes you care about.
Track anything
Seven metric kinds, one quick-add
Amounts, durations, 1–5 ratings, yes/no checks, free-text notes, custom lists and composite metrics built from other metrics. Goals, units and reminder schedules are per-metric, so "Water" and "Deep work" behave the way each one should.
Impacts
See what actually moves the needle
The Impacts engine correlates every factor you track against every outcome — sleep against mood, caffeine against focus, being home against energy. The leaderboard goes further than raw correlation: it isolates each factor's effect by controlling for the others, so one confounder doesn't take credit for everything.
Experiments
Run honest trials on your own life
Turn a hunch into a guided A/B experiment: pick a change, pick an outcome, and Metricky splits your days, tracks both arms and reports the difference with honest statistics — instead of the wishful "I think it's working" you'd tell yourself.
Insights
Advice, not just charts
Weekly summaries, anomaly alerts and "do more / do less" prescriptions distilled from your own isolated-impact data. Smart nudges watch your streaks and usual logging times, and only speak up when tonight is the night a streak would lapse.
Momentum
Streaks that forgive
Life happens. Mark planned skip days, spend streak freezes when a day slips, and keep the chain honest without the guilt trip. Streak rules are per-metric — your daily meditation and your three-times-a-week run both count correctly.
