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).

SimpleStat: Track What Matters in Your Calendar SimpleStat transforms your calendar into a personal statistics engine. Simply define keywords to filter your calendar events—whether it's "Coding," "Duolingo," or any activity you want to track—and watch SimpleStat automatically calculate how often those events occur across multiple timeframes. Smart Calendar Filtering At its heart, SimpleStat filters your calendar events intelligently. Type a keyword, and the app searches your calendar with case-insensitive, localized matching to find every matching event. Whether you're tracking daily habits, weekly goals, or long-term patterns, SimpleStat continuously scans your calendar and builds comprehensive statistics without any manual logging. Two Ways to Visualize Your Data Once you've defined a filter, choose how to track it: Streaks: View your activity as a GitHub-style contribution grid. See at a glance which days you performed your activity, with no target pressure—just the satisfaction of visual consistency. Progress Goals: Set frequency targets (daily, weekly, monthly, or yearly) and watch progress graphs show how close you are to your goals. The home screen displays your current progress clearly, so you know exactly where you stand. Comprehensive Statistics SimpleStat calculates statistics across multiple timeframes—daily, weekly, monthly, yearly, and even by decade. View your data from any angle: compare your busiest days, track average frequency, and analyze long-term trends. All statistics are frozen once created, preserving your history while allowing continuous new data collection. Beyond EventKit's Limits While iOS EventKit only provides access to the last 12 months of calendar data, SimpleStat stores your accumulated statistics in its own database. This means you can build statistical profiles that span years, tracking patterns and progress long after your calendar events disappear from EventKit's view.
