You start something. Something else pulls you away. An hour later you can't remember what you were doing before. Don't Forget is a task timer built for brains that switch. Instead of asking you to stop getting interrupted, it expects interruptions and keeps your place for you, so getting back takes one tap. HOW IT WORKS Start: name what you're working on and go. The timer runs and your task stays front and center. Switch: something urgent comes up? Tap Switch. Your current task is parked with its time saved, and a new one starts. Come back: a minute later, a gentle notification asks if you want to go back. Your parked task is waiting with its timer, steps and notes exactly as you left them. Resume in one tap. BREAK IT INTO STEPS Big tasks are easier to return to when you know the next step. Add steps to any task, focus on one at a time, and see how long each one really took. FOCUS THAT FOLLOWS REAL LIFE Ā· Pomodoro sessions with focus and break lengths you choose Ā· Pause any time, and the timer doesn't keep counting while you're gone Ā· On Mac, tasks pause when your Mac sleeps, locks or starts the screen saver, and resume if you're back soon Ā· A check-in when a timer has been running for hours, so forgotten timers don't skew your day Ā· Fix the time afterwards with "stopped at" if you walked away and forgot to pause PLAN WITHOUT LOSING FOCUS Capture what's up next without breaking your current flow. Plan tasks with due dates and reminders, sort them into folders, and start the next one when you're ready. Finished something you do often? Run it again. SEE WHERE YOUR TIME WENT Honest statistics built from the time you actually focused: focus time, tasks finished, how often you were interrupted, and your sessions by day, week or month. EVERYWHERE YOU WORK Ā· iPhone: Live Activity and Dynamic Island keep your running task visible in any app, plus Home and Lock Screen widgets to start a task Ā· Apple Watch: see your current task and timer, tick off steps, pause, complete, or start what's next, with complications for your watch face Ā· Mac: lives in the menu bar, with a small floating window that keeps your task in view Ā· iPad: a two-column layout with your tasks and details side by side Ā· Your tasks sync across your devices through your iCloud account DON'T FORGET PRO A one-time purchase, no subscription: Ā· Focus patterns: your best hours and days, and what keeps pulling you away Ā· Time by folder: see where your focus goes across projects Ā· Siri & Shortcuts: start, switch and complete tasks hands-free or from automations BUILT FOR PEOPLE WHO SWITCH Many productivity apps assume you'll sit down with a list and work through it in order. Don't Forget is for people whose days don't go that way: people with ADHD, people who hyperfocus and lose track of time, and anyone whose work is full of interruptions. No streaks to break and no guilt. It remembers what you were doing so you don't have to. No account or sign-up needed.
