Stack｜自己投資アプリ vs ONE

自己投資にハマるための今ままでにないプラットフォーム

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.
