STOP LYING TO YOUR CALENDAR. To-do lists feel infinite. If you have ADHD, lists are just a source of anxiety. You keep adding tasks, but reality keeps disagreeing. You schedule 10 pounds of work into a 5-pound day, and then feel guilty when you don’t finish. DayZen: Visual Time Planner transforms your daily schedule from a stressful list into a logical 24-hour visual clock. Tasks become colored arcs. When the circle fills, it’s full. No more pretending a 3-hour project fits into a 30-minute gap. It is the ADHD planner that finally works. Design your time. See your visual schedule. Find your focus. WHAT’S NEW IN VERSION 2.0 We’ve rebuilt DayZen to be the ultimate time management companion for the neurodivergent mind. - Live Activities & Dynamic Island: Track your active focus time, remaining duration, and progress without unlocking your phone. - Immersive Focus Mode: A full-screen focus timer designed to eliminate ADHD distractions, complete with haptic feedback. - Deep Insights: Analyze your time usage patterns with new interactive charts for daily, weekly, and yearly trends.

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, get sick, and track your cycle when it actually happens. When you try to log these irregular events in a normal app, they break your streak and hit you with a red ring of failure. SinceWhen is the "anti-streak" day counter. No guilt, no daily pressure. Just a quiet, stress-free timeline of your actual life. NEW: TRACK MULTI-DAY DURATIONS Not everything happens in a single moment. SinceWhen now supports logging durations from start to finish. • Private Period Tracking: A secure, bloat-free way to track your cycle. No pink themes, no accounts, no data harvesting. • Health & Sickness: Log exactly how many days a fever, migraine, or cold actually lasted. • Travel & Breaks: Track vacations, digital detoxes, or multi-day fasting. Just tap to start and tap to end. Your home screen tracks the current day (e.g., "Day 3"), and your interval charts will elegantly shade the entire duration. 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. SMART PREDICTIONS & INSIGHTS You don’t have to set a rigid schedule. • Learns Your Real Rhythm: Our Pattern-Aware engine calculates your natural intervals. If your routine shifts, SinceWhen instantly recognizes your new rhythm and adjusts expectations. • 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 what is expected today, tomorrow, or overdue via smart, zero-pressure nudges. • Custom Time Display: Tailor exactly how time is counted—choose strict 24-hour periods or calendar midnights crossed. LOG IT IN SECONDS When your hands are full, you don’t want to tap through an app. • Interactive Widgets: 1-tap logging directly from your Home Screen or Lock Screen. • Siri Integration: Just say, "Hey Siri, log the fridge cleaning," and it saves in the background. • Apple Shortcuts: Build custom automations, or trigger logs from Back Tap. YOUR DATA, IN YOUR HANDS Your life is private, and your data stays on your device. • 100% Private: No accounts, no logins, zero data tracking. • iCloud Sync: Seamlessly syncs your logs, pins, and hidden items 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).
