Tiimo is best for
Tiimo is ideal for people who need help structuring their entire day with visual cues. It works especially well for those who benefit from picture-based routines, calendar-style planning, and gentle time awareness throughout the day.
Tiimo is a visual daily planner built specifically for people with ADHD, autism, and other neurodivergent conditions. It uses color-coded visual timelines, customizable routines, and picture-based scheduling to help users structure their day. Tiimo excels at making abstract time feel concrete and visible, with gentle notifications that guide users through their planned activities. The app supports recurring routines, visual checklists, and integrates with Apple and Google calendars. It was designed with input from the neurodivergent community and is widely recommended by ADHD coaches and therapists.
Pricing: Free plan with limited features. Premium starts at $5.99/month or $39.99/year.
OneTask is best for
OneTask is designed for people who can plan their day but struggle with actually starting and completing individual tasks. It strips away all planning features and focuses entirely on executing one task at a time with a dedicated timer, Live Activity, and widgets.
An execution constraint for iPhone. One task at a time, always visible.
Pricing: $3.99/month or $29.99/year
Tiimo is fundamentally a planning tool. It helps you lay out your entire day in a visual timeline with color-coded blocks and picture cues. OneTask deliberately removes all planning. It assumes you already know what you need to do and instead provides a focused execution environment. If your bottleneck is organizing your day, Tiimo is the better fit. If your bottleneck is actually doing the thing, OneTask targets that problem directly.
Tiimo uses rich visual elements like colors, icons, and pictures to make schedules feel accessible and concrete. This works beautifully for visual thinkers and people who need external structure. OneTask takes the opposite approach: it shows you almost nothing except the single task you committed to and a running timer. The lack of visual complexity is intentional — it removes every possible distraction and decision point from the execution phase.
Tiimo keeps you aware of your full day — what is coming next, how much time is left in each block, and where you are in your routine. OneTask narrows your awareness to just right now: one task, one timer, one commitment. For people whose ADHD causes time blindness across the whole day, Tiimo provides that big-picture view. For people who get paralyzed by seeing too many tasks ahead, OneTask removes that cognitive load entirely.
Tiimo was co-designed with the neurodivergent community and includes features specifically requested by users with ADHD and autism. Its design reflects years of feedback from coaches and therapists. OneTask is built around a single behavioral principle: that constraining choice to one task reduces executive function demands. Both approaches are valid — Tiimo listens to what users want, while OneTask enforces what behavioral science suggests works for task initiation.
Tiimo and OneTask serve different stages of the productivity process. Tiimo is an excellent choice if your main challenge is structuring your day, building routines, and maintaining awareness of time throughout the day. Its visual approach is genuinely innovative and deeply thoughtful in its neurodivergent-friendly design. OneTask is the better choice if your challenge is not planning but doing — if you can make a to-do list but cannot make yourself start the first item. It acts as an execution constraint that forces single-task focus with a timer. Many ADHD users may benefit from both: use Tiimo to plan the day, then use OneTask to execute each task one at a time. They are complementary rather than competing. Choose Tiimo if you need help knowing what to do and when. Choose OneTask if you need help actually starting and finishing.
