You can use the provided widgets to help keep your item front and center throughout the day.

Do This is a to-do app that holds exactly one task. Long lists are where ADHD brains get stuck. Every item is another decision about what to do first, and the list ends up being the thing you work on. Do This skips all that. Type the one thing you're doing right now, do it, tap done, then type the next one. • One task at a time. No lists, no due dates, no setup. • Always in view: on your Lock Screen as a Live Activity, in the Dynamic Island, and in home screen widgets. • Finish without opening the app. Tap done from the Lock Screen, a widget or your Apple Watch. • Optional reminders that nudge you until the task is done. • Quietly keeps time, so you can see how long you've been at it. • Undo, in case you tap done by accident. • Siri and Shortcuts support. One-time purchase. No subscription, no ads, no account.
