You know what to do — you just can't start. And when you finally do, your phone pulls you away. Dino is a task timer built for exactly that: pick one thing, press start, and it stays in your Dynamic Island until you're done. Designed around ADHD traits — procrastination, distraction, and time blindness. ■ One task at a time No long lists, no due dates, no priorities. Write one task and press start. Less choosing, faster starting. ■ It stays until you're done Your running task lives in the Dynamic Island and on the Lock Screen as a Live Activity. Even when you wander into other apps, the task and its timer never leave your sight. ■ Three timer modes - Stopwatch: just track elapsed time - Timer: get notified after a set duration - Pomodoro: automatic work/break cycles ■ Focus Guard (Dino Pro) Block distracting apps while you focus. Unlocks automatically during breaks and pauses. ■ No guilt on off days Only what you finish is recorded. Broken streaks cost you nothing. Daily wins and a weekly graph quietly stack up the proof that you did the thing. ■ Also - Live Activity mirrored to Apple Watch Smart Stack - iCloud sync across your devices - Repeat-task templates The name? Do It Now + One task. Dino. ■ Terms & Privacy - Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ - Privacy Policy: https://quusoh.co.jp/apps/dino/privacy

One Thing is a deliberately tiny task app for anyone who freezes in front of a long to-do list — especially ADHD brains. Instead of a wall of overdue items, it shows you exactly ONE thing to do right now, with a single big "Done" button. That's it. Come back after two minutes or two hundred days, and the screen looks the same. No streaks to break. No red badges. No shame. WHY ONE THING IS DIFFERENT • One task at a time — Your whole list is real, but you only ever see the next thing. Less overwhelm, more starting. • Break it down — When the one thing still feels too big to begin, tap "Break it down" and split it into tiny steps. The first small step becomes your new "right now." Momentum, not pressure. • Zero shame by design — No streaks, no penalties, no guilt-red badges. Miss a day or a month; nothing breaks. Pick up whenever you're ready. • Gentle reminders — Optional, fully under your control, with a soft chime instead of a jarring alarm. They never fire when your list is clear — the app won't nag you about nothing. • A calm widget — See your one thing on the Home Screen or Lock Screen, and check it off without even opening the app. • A little celebration — Finishing feels good. A quiet, rotating celebration marks each "Done." PRIVATE BY DESIGN One Thing collects no data — none. No account, no tracking, no analytics, no servers. Everything you write stays on your device. Privacy isn't a feature here; it's the foundation. Do the one thing. Breathe. That's enough.
