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. LOG IT IN SECONDS • Home Screen and Lock Screen widgets • Undo an accidental tap right where you made it • Siri and Shortcuts: "Hey Siri, log haircut" • Add a note, or backdate a log in a couple of taps EVERYTHING AT A GLANCE • Calendar with a ring on the next expected day • Interval and monthly charts • Categories with their own insights • Pause an event while you're away so predictions stay honest • Grid or list, pin what matters, dark mode, iPhone and iPad PRIVATE BY DESIGN No accounts, no ads, no analytics. Your timeline stays on your device and in your own iCloud. Export everything as JSON any time. FREE TO START Your first 3 events are free forever with every core feature.
