Streamline your life with Timelane, an all-in-one productivity app with a focus on simplicity. Combining the power of Apple's Calendar and Reminders apps, Timelane helps you effortlessly manage your schedule, set and track repeating items, and stay on top of tasks with deadlines. Say goodbye to juggling multiple apps and hello to simple organization. Important: Timelane requires full access to your Calendar and Reminders apps in order to function. Features: - Unified list view that shows today's items and the items for the next several days - Calendar view for looking at any date in the past or future - Inbox to hold tasks with no assigned date - All data is stored in Apple's Calendar and Reminders apps, so your data is safe if you delete the app - Log view for looking at completed items - Any task can be made a deadline (it will then show the remaining days each day until completed, so you'll never forget it) - If you complete a repeating task after its due date, Timelane asks if you want to schedule the next occurrence based on the original due date or based on the current date - You can select which calendars and lists to show - Several widgets show the remaining items for the current day, or can just function as a simple calendar view - Notifications can show on all your devices, and can be toggled on/off per calendar/list. A few notes before purchasing: Timelane acts as a unified interface to Apple's Calendar and Reminders apps, and thus all of your data remains safely stored in those apps and in iCloud (even if you ever delete Timelane). This app has been designed to specifically work with those two apps, and is actually fine to be used alongside them. A "deadline" is a specific task with an assigned date that will show a daily reminder that it is coming up, so you'll never forget (the app uses a "low priority" flag from Reminders to signify a deadline). Something not working? We realize that there are many things that could've been overlooked when creating this app, and bugs do sneak in. If something is not working or not displaying properly, feel free to contact us! We will get it fixed as quick as possible.

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.
