One Question Journal
Read full descriptionHide full description
One question per day. That's it. Every day, a single question appears. You answer it once—then it's locked. No editing. No rewriting. No polishing. Just honest reflection. Written on paper, not on a screen. Serif type, warm ink, a page with grain. The question is the title and the rest of the page is yours. Why it works: • One thought a day, finished and set down • A record that builds itself while you're not looking • Private enough to be honest in Every day: • A new question each morning, and a reminder at the hour you actually write • Answers lock the moment you save • Mark how you felt, or leave it blank • A few words back after you write, drawn from the week behind your entry Looking back: • Past Entries as a timeline you can search and filter by mood • On This Day — what you wrote a week, a month, six months, a year ago • Year in Review — the whole year as a calendar of moods • Insights — streaks, patterns, and weekly and monthly reflections Wherever you write: • Apple Watch, with dictation and complications • Apple Vision Pro, for writing in a space of your own • Home Screen and Lock Screen widgets • iPad, in split view Yours to keep: Your entries stay on your device and sync only through your own iCloud account. Nothing you write is used for analytics. Export everything as plain text whenever you want. Open the app. Reflect. Answer. Close. Repeat. Simple. Private. Yours. -- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
