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
