Most productivity apps overwhelm you: tasks, projects, dashboards, notifications fighting for attention. One Thing goes the opposite way. You choose exactly ONE goal that matters to you β€” read 20 pages, run 2 km, meditate 10 minutes, write 500 words β€” and you check in every single day. The streak counts. The streak motivates. One day at a time. HOW IT WORKS β€’ Set your one thing β€” give it a name in seconds, change it anytime. β€’ Check in daily β€” one tap. Add a short note if you like. β€’ Watch your streak grow β€” the number keeps you honest. β€’ Share your progress β€” generate a beautiful share card with your day count, your goal, and a QR code friends can scan to download. β€’ Get reminded before you break the chain β€” a local daily notification warns you when your streak is at risk. Check in, and today's reminder is skipped automatically. The app-icon badge shows the days at stake and clears the moment you check in. β€’ Your data stays yours β€” everything is stored locally on your device. No account, no sign-up, no server, works fully offline. WHY ONE THING β€’ Zero clutter: one screen, one number, one tap a day. β€’ Honest design: no gamified noise, no social pressure β€” just you and the streak. β€’ A tip jar, not a paywall: One Thing is free; an optional one-time tip supports development and unlocks nothing. A HISTORY OF STEADY IMPROVEMENT β€’ v1.3.0 β€” Real daily "streak at risk" reminders, delivered right on time. β€’ v1.3.4 β€” Reminder engine rebuilt as a 30-day rolling window: notifications keep working for weeks even if you never reopen the app. Streak-count app badge added. β€’ v1.3.5 β€” Badge handling rewritten to talk to iOS directly: check in, badge gone. Instantly and reliably. β€’ v1.3.6 β€” New home at dch.ltd (share-card QR code, support email, legal pages) and a greatly expanded FAQ, including a note on a known iOS photo-picker issue when choosing screenshots. One goal. One streak. Every day. Made with care by Dream Collection Hall LLC. Website: https://dch.ltd Β· Support: support@dch.ltd

About

UNTIL Timer

Read full description

UNTIL Timer is a simple way to manage your focus with a finish time. Instead of setting β€œ30 minutes” or β€œ60 minutes,” choose the clock time you want to reach. UNTIL turns that time into a small, visible deadline and shows you exactly how much time is left. A FINISH TIME FOR BETTER FOCUS When a task has no clear edge, attention can drift. UNTIL gives what you are doing now a finish line. Not a complicated schedule. Not another productivity system. Just a clear β€œuntil.” SET A TIME. FOCUS ON NOW. Use UNTIL for: β€’ Finishing a focused work session β€’ Getting ready to leave β€’ Study and homework β€’ Creative work β€’ Chores and household routines β€’ Breaks and transitions β€’ Any task that needs a clear finish line SMALL DEADLINES, THROUGHOUT YOUR DAY The real deadline may be tomorrow, next week, or months away. UNTIL lets you create smaller deadlines inside today. β€œI’ll work on this until 10:30.” β€œI’ll get ready until 8:15.” β€œI’ll finish this part by 3:00.” A small finish line can make it easier to give your attention to what matters now. SIMPLE BY DESIGN β€’ Set an end time instead of calculating a duration β€’ See remaining time at a glance β€’ Get an alarm or notification when time is up β€’ Keep the countdown visible when you want it β€’ Save timers you use again UNTIL PRO Get more from every countdown with UNTIL PRO. Save, organize, repeat, and personalize the small deadlines that shape your day. UNTIL isn’t about managing every minute. It’s about managing your focus. Pick a time. See what’s left. Focus on now.
