Most of us don't struggle with knowing what to do. We struggle with starting — because the phone is always easier. Donera flips the order: finish today's one important thing first. Until then, your distracting apps stay locked. HOW IT WORKS 1. Pick one Highlight — the single task that matters most today. 2. Choose the apps that steal your attention. Donera locks them. 3. Hold to finish. Your apps unlock, and the day is closed. WHY IT WORKS • One thing a day. Your home screen shows only this one — no lists, no counts, no overwhelm. • Blocking that holds you to your word. Built on Apple's Screen Time framework — no VPN, and nothing leaves your device. • Something urgent? Open it anytime. Take a 30 or 60 minute break, as many per day as you allow yourself — or unlock on purpose, with nothing recorded and no guilt trip. • Multi-day plans. Split a goal into days; each morning the next step becomes your Highlight. Or let an AI draft a plan for you and import it. • Ranks. Finished days add up — from Mortal to Eternal — and only ever go up; a missed day never drops you. Four built-in systems, or make your own. • Widget and Live Activity. Today's one thing, in sight on your Home and Lock Screen. DESIGNED FOR QUIET Warm paper, ink, and serif type. No tags, folders, or dashboards. No guilt. Your tasks stay on your device. Donera doesn't ask you to become disciplined. It simply helps you begin more easily — and finish with more care.
