A to-do list where every task comes with a timer. Most lists tell you what to do. This one starts the clock, which turns out to be the part that actually gets you moving. HOW IT WORKS - Add a task and give it a length - Tap to start; the timer runs while you work - Finish and it is checked off, with the time recorded WHY A TIMER HELPS Deciding to start is the hard part. "Study for twenty minutes" is a decision you can make; "study" is not. Putting a number on the task makes the first step small enough to take. BUILT FOR - Study sessions and exam prep - Workouts and stretching - Chores you keep putting off - Anything you want to do a little of, every day SEE YOUR PROGRESS Completed tasks and time spent are recorded, so the streak has something concrete behind it. Simple, quick to set up, and no account required.
