Focus One
Read full descriptionHide full description
Focus One is a simple focus timer for people who want to start one task, stay with it, and reduce mental clutter. Choose what you will do now, set a timer, and begin. The app keeps the screen quiet so you can return to the one thing in front of you. The settings screen lets you choose the app language, so the app can be localized to the language you select. Useful for study, work, Pomodoro-style sessions, ADHD-friendly routines, and building a visible focus record over time.
What to
Read full descriptionHide full description
Not another list. The thing that picks. You have forty things and no idea which one to do right now. What to: Do asks two questions โ how long you've got, how much you've got in you โ and answers with one task. Not five options. Five options is the list again. WHAT IT DOES โข One answer, every time. One task, the reason it won, and the opening move so you don't stall on "where do I even start". โข It shows its working. Every pick argues its case: what's urgent, what's quick, what you've been avoiding, what you actually have energy for. โข Only ever what you wrote. It never invents a task. Everything it offers came from you โ typed, dictated, brain-dumped, or read in from Reminders. โข One sentence in, we read the rest. Capture is one field. It infers how long a task takes and what kind of thing it is from the words you used. โข Nine in the morning, the task itself. Not a badge count โ the actual thing worth starting, on your lock screen. โข Passed on it four times? One question, and either answer ends it. Lists rot; this one gets swept. โข How often the pick was right. The only score that matters, and the only one it keeps. BUILT TO BE LEFT, NOT LIVED IN Two taps and you're gone. There is no inbox to process, no projects to maintain, no system to keep up with. Bring your list from Reminders and keep using whatever you already use to capture โ this is the layer that decides. FOR THE DAYS DECIDING IS THE HARD PART If executive function is the bottleneck โ ADHD, burnout, or just a bad Tuesday โ the work isn't writing things down. It's choosing. This does the choosing. WHATTO PLUS One subscription across What to: Do and What to: Wear. Unlimited tasks and connected lists. The app works without it.

Verdict
The clearest difference is in-app purchases: Focus One at none against What to's 2. Focus One also leads on iOS requirement (18.0 vs 26.0). What to's advantage is ads (none vs shown). On price, update cadence and device support there is nothing between them.
