Stop asking, "When did I last do that?" SinceWhen is the guilt-free "days ago" and time since tracker built for real life. Standard habit trackers demand daily streaks, but most of life doesn't happen every 24 hours. You change the AC filter, water plants, get a haircut, or track your cycle on an irregular schedule. Logging these in a normal routine app breaks your streak and hits you with a red ring of failure. SinceWhen is the anti-streak event log and day counter. No daily pressure—just a clean, stress-free timeline showing exactly how long it has been since the last time. TRACK ANY IRREGULAR ROUTINE OR CHORE Built for the messy, easy-to-forget life maintenance tasks that daily streak apps ignore: • Home & Cleaning: AC filters, deep cleaning the fridge, washing bedsheets, descaling coffee makers, checking smoke detectors. • Plant & Pet Care: Unpredictable watering schedules, fertilizing, flea and tick treatments, vet visits, grooming. • Car & Life Admin: Oil changes, tire rotations, haircuts, dental checkups, calling family. • Health & Self-Care: As-needed medication, vitamins, pain relief, replacing contact lenses, skincare actives. • ADHD-Friendly: A zero-shame, visual task history designed for time blindness and executive dysfunction. LOG MULTI-DAY DURATIONS Not every event happens in a single moment. Track multi-day events from start to finish: • Private Period Tracker: A secure, bloat-free way to log your cycle with no accounts or data harvesting. • Sickness & Symptoms: Record exactly how many days a fever, migraine, cold, or burnout lasted. • Travel & Breaks: Track vacations, trips, guests visiting, or fasting. Tap once to start and tap to end. Your home screen counts the active days ("Day 3"), and your interval charts shade the entire duration. SMART PREDICTIONS & INTERVAL INSIGHTS You don’t need a rigid schedule to stay on top of things: • Learns Your True Rhythm: Our PatternAware engine calculates the natural intervals between your logs, automatically skipping one-off long gaps (like vacations) to learn your real routine. • Gentle Nudges, Not Nags: See what is expected today, tomorrow, or overdue based on your actual history. • Pause Anytime: Traveling or injured? Pause any event so your predictions stay accurate and notifications stay quiet. • Interactive Calendar & Charts: Tap any date on your Insights grid to review past logs, notes, and monthly totals. • Custom Time Counting: Choose between strict 24-hour periods or calendar midnights crossed. LOG IT IN SECONDS (WITH INSTANT UNDO) When your hands are full, log without slowing down: • Interactive Widgets: 1-tap logging directly from your Home Screen or Lock Screen. • Accidental Tap Undo: Tapped a widget by mistake? Instantly undo accidental logs right from the Home tab, widgets, or Lock Screen. • Siri & Apple Shortcuts: Say, "Hey Siri, log the fridge cleaning," or build custom automations. 100% PRIVATE & IN YOUR HANDS • Zero Tracking: No accounts, no sign-ups, no ads, and zero analytics. • iCloud Sync & Backup: Seamlessly sync across iPhone and iPad with automatic iCloud Drive backups. • Full Data Ownership: Export or import your entire timeline as JSON anytime (SinceWhen_Latest.json). SINCEWHEN PRO Start free forever with your first 3 events—every core feature included, no credit card required. Upgrade to SinceWhen Pro for unlimited events, full iCloud sync, Siri & Shortcuts, and JSON export: • Monthly & Yearly: Includes Apple Family Sharing so your household can track chores, pets, and home maintenance together privately on their own Apple IDs. • Lifetime: A simple one-time purchase to own it forever (Family Sharing not included).
