Your day, one calm timeline. Free to try for 14 days. Tether puts your tasks, calendar events, and reminders on a single vertical timeline, so you always know what's now and what's next. ONE TIMELINE FOR EVERYTHING Your whole day, top to bottom. Items closer to now are visually emphasized, so your attention lands on what matters in this moment, and everything shifts in real time as the day moves. Calendar events sit alongside your tasks, not in a separate app. Add, edit, complete, or drag something to a new time right from the timeline. Block out time for a task and it appears on your real calendar. REMINDERS THAT DON'T GIVE UP One notification is easy to miss, or to dismiss without thinking. Tether's reminders can escalate, checking back in while something still needs you. Get a heads-up before a task starts, not just as it begins, so there's time to actually switch gears. Reminders can also trigger when you arrive somewhere or leave it. FOCUS MODE When it's time to work, Focus narrows everything to one task and a timer. No feed, no competing notifications. The timer stays live on your Lock Screen and in the Dynamic Island, so it's visible without opening anything. CAPTURE IN SECONDS Offload an idea the moment it shows up and sort it out later. Type "gym tomorrow at 7" and Tether reads the date for you. Add repeating tasks, subtasks, and photos. Capture from anywhere: a Home Screen widget, the share sheet from any app, or Siri, hands free. ON EVERY DEVICE YOU USE Widgets show what's next without opening the app. Your day syncs to Apple Watch, so you can check tasks off from your wrist. Everything stays in sync across your own devices through iCloud. BUILT FOR HOW YOUR DAY ACTUALLY GOES Tether was shaped by feedback from people who deal with time blindness, executive functioning challenges, and the struggle of holding a day together in their head. It's built for all of that, and it works just as well for anyone who wants a calmer, clearer view of their day. PRIVACY, BY DESIGN No accounts. No login. No tracking. No analytics. Your data stays in your private iCloud account and syncs across your own devices through Apple's CloudKit, never through our servers, because we don't have any. Tether's App Store privacy label says exactly what it should: Data Not Collected. FREE TO TRY, THEN ONE PRICE Tether is free to download, with every feature unlocked for 14 days. No account, no card, nothing to cancel. After that, one purchase unlocks Tether for good. No subscription, no ads, no upsells, and all future updates are included. If the trial ends before you've decided, nothing is deleted or hidden. Your timeline, your reminders, and everything you've added stay exactly where they are, and you can still check tasks off. Adding and editing pick back up the moment you unlock. Made by Quiet Leaf, a small studio building calm tools for how minds actually work.
