Propelo is the ADHD task manager that doesn't become another task. Instead of projects, folders, and separate lists to maintain, Propelo keeps everything in one prioritized list. Your tasks stay visible, easy to reorder with drag and drop, and much harder to forget. Propelo keeps task managementβboth in your head and in the appβto a minimum, with a system designed specifically for people with ADHD. Start your 14-day free trial. A Google account is required because Propelo plans tasks around Google Calendar. WHY PROPELO WORKS FOR ADHD Traditional task apps often ask you to organize before you can act: projects, inboxes, tags, priorities, streaks, and overdue lists that eventually need managing themselves. Propelo removes as much of that maintenance as possible. There are no streaks or productivity scores. Your tasks stay in one ordered list, with a clear next task and nothing going stale simply because you didn't finish it on a particular day. Need to focus on one area? Filter your list by Goal without creating or maintaining separate lists. Open Propelo, plan your day in under 30 seconds, and get back to doing. ONE LIST, ONE ORDER Everything stays in one flat, prioritized list. No project hierarchies, separate lists, or hidden tasks. Everything shares the same underlying priority order, even snoozed and recurring items. Prioritize by comparing two tasks at a time instead of assigning complicated priority labels. The task at the top becomes today's mission. START WITH A COMICALLY SMALL ACTION For many people with ADHD, starting is the hardest part. Once you begin, continuing is much easier. Propelo generates an intentionally tiny first physical action for each taskβsometimes as small as βstand up and walk to your deskββso you can start moving before your brain has time to turn the task into something overwhelming. AUTOMATIC GOOGLE CALENDAR SYNC Propelo places due dates and tasks into open slots in Google Calendar. Unfinished work rolls forward automatically. GOALS THAT STAY CONNECTED TO YOUR PRIORITIES Group tasks by Goal without splitting your work into separate lists. Focus on one Goal, reorder its tasks, then return to your full list with those priority changes automatically preserved. Give a Goal a target date and Propelo can warn you when its tasks are currently prioritized too low to finish in time. DYNAMIC COMPLETION ESTIMATES Month-by-month completion markers appear directly in your task list, showing roughly how far down the list you're likely to reach by the end of each month. This makes it easier to see what realistically fits, move deadline-sensitive work higher, and deprioritize less urgent tasks without building a complicated long-term plan. RECURRING TASKS AND SNOOZE Recurring tasks appear above the Today Line when due and stay there until completed. Snooze anything that doesn't need your attention yet. It disappears for now and returns when you need it. ALWAYS VISIBLE WITH WIDGETS AND NOTIFICATIONS The biggest risk with any ADHD tool is forgetting it exists. See your next task from your Home Screen, get a reminder when your day begins, and see tasks and due dates in Google Calendar. BUILT BY A PROJECT MANAGER WITH ADHD Propelo is for people who have abandoned task apps because maintaining the app eventually became harder than doing the tasks. Start your 14-day free trial today.
