Some tasks just feel too much. And when new ones come up, we often tackle them first — even if they’re not that important. "Shiatomawa" takes a different approach. It’s a task manager designed around a simple rule: do things in the order you added them. [Tasks always go to the end] Every new task is added to the bottom of the list. [Focus on the one at the top] All you need to do is handle the task at the very front — one by one. [Only two actions: “Done” or “Later”] Decide whether to do it now or postpone it. There’s no sorting, no reordering — ever. On devices that support Apple Intelligence, your AI assistant will cheer you on. Even when you’re stuck on a tough task, it might just give you the push you need.

Not another to-do list. ONE Focus is a single-task focus timer for a deeper life. You commit to one thing at a time—nothing else on screen, nothing competing for your attention. WHY ONE FOCUS? • One thing only — no lists, no tabs, no clutter • Start in one line — type a title, press return, begin • Gentle accountability — a progress check-in every 45 minutes • Five-step progress — 0, 25, 50, 75, or 100%, with an optional note • Quiet by design — no streak anxiety, no gamification, no noise • Night quiet hours — no notifications between 22:00 and 09:00 • Minimal history — see what you've finished, nothing more HOW IT WORKS 1. Enter one thing and start 2. Stay with it — elapsed time keeps you honest 3. Respond to check-ins when prompted (or update progress anytime) 4. Mark complete when you're done 5. Move on to the next moment DESIGNED TO FEEL CALM Editorial Noir typography, generous whitespace, and champagne-gold accents. Dark-first. No feature bloat. No account required. Everything stays on your device. Built for focus, study, deep work, and everyday presence—reading to your child, cooking a meal, taking a walk, creating something meaningful, or simply being here. Download. Pick one thing. Live it fully.

Verdict
The clearest difference is update cadence: Shiatomawa at every 2 days against ONE's every 2 weeks. ONE's advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
