Stop managing to-dos. Just remember when you last did it. "When did I last wash the sheets?" "When did I change the water filter?" "When did I last call my parents?" Some things you can never remember. When'd I records just the date you did them. No goals, no nagging notifications, no checklists. Tap once and it's logged as today. ■ See how long it's been Every item shows the days since you last did it. The longer it's been, the more it stands out. ■ A timeline where distance means time The space between dots is the actual gap between dates. Busy stretches look dense. The months you skipped show up as empty space. ■ Photos and notes Attach one photo and a short note to any record. ■ Widgets and Lock Screen Check what's overdue from your Home Screen, and log without opening the app. You can even record straight from the Lock Screen. (iOS 16.4+) ■ An optional evening nudge Once a day, if you want it. Off by default. ■ Entirely on your device No account, no server, no ads. Your records stay on your phone. Export and import backup files yourself, and an automatic iCloud copy brings everything back if you switch phones or reinstall. ■ Buy once One purchase unlocks everything. No in-app purchases, no subscriptions, no ads.
