One question a day. A single line is enough. Q Diary is a journal that gives you one question every day. No staring at a blank page, wondering what to write. Answer today's question however it comes to you, and that's your entry. The same question comes back on the same date every year. Last year's answer sits right below this year's, so you can see at a glance what has changed and what hasn't. Keep writing for three years and you'll have three years of answers to the same question on a single page. [A few of the questions] January 1: What are your goals for this year? January 12: If you could describe your day in a color, what would it be and why? February 11: What is something you have lost sight of in your life? Take a moment to think about it. March 26: In the far future, when you are much older than you are now, what kind of life do you imagine you will be living? April 7: What is making you smile the most these days? October 10: If you could erase one memory from your mind, which one would it be? December 30: Do you feel that you have changed a lot over the past year? What has remained the same and what has changed? [Pick a question set] - Basic: 366 questions for getting to know yourself, one for every day of the year - Emotional: questions about your mood and the small moments of your day "On the first day of the new year, what was the first word that came to mind?" - Action: questions about what you did today, and what you might do a little differently tomorrow "What did you do better today than yesterday?" - 30 Days After a Breakup (Plus): a 30-day course to work through it, one question a day If today's question doesn't speak to you, swap it for one from another set. Free includes one swap a month, and Plus has no limit. [Features] - Year over year: every answer you've written for a date, on one screen - Calendar and search: see which days you wrote, and find old entries by keyword - Photos and voice: add photos to an answer (3 a month free, unlimited with Plus), or just talk and let the app write it down - Voice answer reminder: tap the reminder to hear the question, then just talk and the app writes it down (more accurate server transcription 5 times a month free, every time with Plus) - Year in review: a calendar of the days you wrote (stats like total characters and your longest streak, plus a share card, with Plus) - Themes: pick a question style (color themes and a serif font with Plus) - App lock: keep your journal private with a passcode - Reminders: get today's question at the time you choose - Sync: sign in on a new phone and your entries come with you - Try it as a guest, no sign-in needed - Book-style PDF: save a year of entries as a PDF with a cover you design (Plus) [Q Diary Plus] Features marked (Plus) require a Q Diary Plus subscription (monthly or yearly), which also removes ads. The 30 Days After a Breakup course is also available as a one-time purchase. A minute a day is all it takes. A year from today, you can look back at what you're writing now.

Most journals stall at the same place: the blank page. You open the app, don't know what to write, and close it again. OneQ takes that moment away. Every day it asks you one thoughtful question β€” about your day, your people, your memories, the things you're grateful for, the person you're becoming. You answer in two quiet minutes: a few honest lines, a mood, maybe a photo. Done. See you tomorrow. ONE QUESTION A DAY β€’ 1,300 hand-written questions in ten flavors β€” gratitude, memories, people, growth, small comforts, and some just for fun β€’ More than three years of daily questions before one repeats, in an order shuffled just for you β€’ The same question all day, a new one at midnight β€” nothing to choose, nothing to plan β€’ A gentle streak that never breaks before the day is over A JOURNAL THAT FEELS LIKE ONE β€’ Questions and answers set in warm serif type, on a calm canvas in light or dark β€’ Five hand-drawn mood faces, one tap β€’ Add a photo straight from your library β€’ Edit anything, anytime β€” it's your journal WATCH YOUR STORY GROW β€’ Every answer on one timeline, a day at a time β€’ Your streak, your answers, and every word you've written, counted in Insights KIND REMINDERS β€’ One optional nudge a day, at the time you choose, with that day's question in it β€’ Already answered? The reminder quietly steps aside PRIVATE BY DESIGN β€’ No account. No cloud. No feed. β€’ Your journal stays on your device. No one else ever reads it. ONEQ PLUS An optional upgrade for going deeper: β€’ Five more themes β€” Dawn, Ocean, Meadow, Ember, Orchid β€’ Mood insights: see how your moods balance out, mapped day by day β€’ On this day: your own words from a week, a month, a year ago β€’ Search everything you've ever written One question. One answer. One small moment a day that adds up to the story of your life.
