What's the simplest ADHD-friendly planner?

If simplicity is the goal, Orby and Tiimo are currently the easiest ADHD friendly planners to live with. Both minimize the two things that kill most planning apps: heavy setup and constant maintenance. Tiimo keeps everything visual with color coded routines and a clean today view, which suits people who think in pictures. Structured is also simple on the surface with its timeline layout, though useful features like repeating tasks sit behind its paywall. Motion is powerful but adds complexity and costs around $34 per month. Orby is arguably the lowest effort of the group: you dump your goals in plain language, its AI plans your week around your existing calendar, and you mostly just follow along. There are no streaks or shame mechanics, and plans start at $4.99 weekly with a three day trial.
