Not everything is a daily habit. SinceWhen tells you how long it's been since the last haircut, oil change, vet visit, or dose, and when it's likely due next. One tap to log. No streaks. No guilt. No account. HOW IT WORKS • Name something you do now and then • Tap to log it, from the app, a widget, your Lock Screen, or Siri • SinceWhen learns your rhythm and shows what's due BUILT FOR REAL LIFE • Home & car: AC filters, oil changes, smoke detectors, deep cleans • Plants & pets: watering, fertilizing, flea treatments, vet visits • Health & self-care: as-needed medication, vitamins, skincare, dentist • Life admin: haircuts, calling family, reviewing subscriptions • ADHD-friendly: a zero-shame history for time blindness SMART, GENTLE PREDICTIONS SinceWhen studies the gaps between your logs and says things like "Usually every 6 weeks" and "Expected tomorrow". Pattern aware skips one-off long gaps, like a week away, and follows your real routine. Optional nudges arrive only when something is actually due, and you can log straight from the notification. MULTI-DAY EVENTS Tap once to start, tap again to end. Trips, sick days, and cycles are counted as Day 1, Day 2, and so on, with the full duration shaded on your charts.
