Stop asking, "When did I last do that?" Standard habit trackers demand daily streaks. But real life doesn't happen every 24 hours. You change the AC filter, wash the pillows, and give the dog flea meds when they need it. When you try to track these irregular chores in a normal app, they break your streak and hit you with a red ring of failure. SinceWhen is the "anti-streak" tracker. No guilt, no daily pressure. Just a quiet timeline of your actual life. TRACK ANY IRREGULAR ROUTINE We built this for the messy, easy-to-forget maintenance tasks that streak-based apps ignore. • Home Maintenance: AC filters, deep cleaning the fridge, washing bedsheets, checking smoke detectors. • Plant & Pet Care: Unpredictable watering schedules, repotting, flea and tick medication, grooming. • Car & Life Admin: Oil changes, tire rotations, haircuts, dental visits. • Health & Self-Care: Irregular vitamins, pain relief, eye drops, replacing contact lenses. • ADHD-Friendly: A zero-shame, zero-streak visual history for executive dysfunction. LOG IT WITHOUT LOOKING When your hands are full, you don’t want to tap through an app. • Siri Integration: Just say, "Hey Siri, log the fridge cleaning," and it saves in the background. • Apple Shortcuts: Build custom automations, trigger logs from Back Tap, or use Lock Screen widgets. SMART PREDICTIONS & INSIGHTS You don’t have to set a rigid schedule. • Learns Your Rhythm: SinceWhen calculates your natural intervals and gently predicts when a task is actually due next. • Interactive Calendar: Tap any day on your Insights grid to see exactly what you did and the notes you left. • Due at a Glance: See exactly what is expected today, tomorrow, or overdue right on your home screen. YOUR DATA, IN YOUR HANDS Your life is private. • 100% Private: No accounts, no logins, zero data tracking. • iCloud Sync: Seamlessly updates across your iPhone and iPad. • Direct File Access: Auto-backups save directly to your iCloud Drive Files folder (SinceWhen_Latest.json) so you can build your own custom scripts. SINCEWHEN PRO Start completely free. Track your first 3 events forever, no credit card needed. Upgrade to unlock unlimited events, full iCloud sync, Siri logging, and interactive insights: • Monthly: Includes Apple Family Sharing. • Yearly: Includes Apple Family Sharing (Best subscription value). • Lifetime: A simple one-time purchase to own it forever (Family Sharing not included). With Family Sharing (Monthly/Yearly), your entire household can track chores, pet care, and home maintenance together—each using their own Apple ID, keeping everything fully private.
