The planner for days that don't go to plan. On iPhone, iPad, the web and your computer. With Pro it all syncs, and Yoodoo works with Claude and ChatGPT: plan your day in a chat and it lands on your timeline. Most planners work until about 10am. Then a call runs long, you lose an hour to your phone, or you just don't start, and the whole day gets written off. Yoodoo expects that. It fits the rest of your day around what actually happened, so you keep going. Built ADHD first, for every brain that's wired a little differently. Diagnosed, on a waiting list, just pretty sure, or simply juggling too much. If your days keep breaking, it's for you. GET IT OUT OF YOUR HEAD - Say or type everything that's on. Ask Yoodoo turns it into tasks, files them into lists and plans the day, times and all. - Lists for everything else, with one star for what matters. A DAY YOU CAN ACTUALLY DO - A real timeline where an hour looks like an hour, with your calendar in it. - Plan today: tick what's happening, pick the one that matters, and Yoodoo builds your day around what can't move. Breaks included. - See how long you've got before the next thing, not just the time it starts. Handy if time blindness is your thing. HELP TO START - Just start: five minutes and a timer. The hardest bit of a big task, done. - Focus shows one step at a time, so a mountain becomes the next small thing. - Steps: Yoodoo cuts a big task into tiny ones, and the first is so small you just start. - Block the apps that pull you away, on a schedule or right now. FIX MY DAY, WHEN IT SLIPS - Something ran over? Yoodoo asks one simple question and moves the rest. - Behind on a few things? See what still fits, and let the rest roll to later. Your day's priority stays protected. - Things you didn't get to roll on. They never pile up and never turn red. - Nothing changes until you say Looks right. FEEL GOOD AT THE END OF THE DAY - Wrap up in three taps: what's done, what moves, and tomorrow's ready. - Habits and routines that run on a timer, with no streak shaming. - A week's story that shows what you actually got done. ALL IN ONE PLACE Planner, to-do list, focus timer, app blocker, habit tracker and calendar, working together. Widgets, Live Activities, Siri, task alarms for the things you can't miss, and Yoodoo on the web and your computer too.
