QuestionDiary
Read full descriptionHide full description
QuestionDiary asks you one question a day. Answer it in a few lines, and one year later, on the same date, meet the person who wrote it. ■ One question a day Every morning a question arrives: "What made you smile today?" A few lines are enough. Questions are tied to the calendar date, so the same question returns on the same day each year. 366 questions across eight themes (self, relationships, daily life, memories, feelings, dreams, growth, gratitude) are built in, and you can swap any of them for your own or one from the Plaza. ■ A year later, your answer comes back When the same date comes around, the answer you wrote appears again on today's screen. After two or three years you see every year's answer to the same question side by side. Swapping a question later never changes what you already wrote. ■ Journal Look back through a calendar and a timeline, search your answers, and track your streak and how much of the year you've filled. ■ Plaza A place where people post questions they'd like to ask each other. Bring any of them into your own diary. Posts show no names or identifiers, and you can report or block. ■ Only on your device Answers stay on this iPhone by default. Start without an account or email. Turn on Backup only if you want it, then a single 10-character code moves everything to a new device. Lock the diary with Face ID. ■ Reminders Get the day's question once, at the time you choose. If you've already answered before then, that day's reminder stays quiet. You'll also hear when an answer from a year ago arrives. Ads, but no tracking: the app never asks for tracking permission, and your diary is never used for analytics.

Verdict
The clearest difference is in-app purchases: QuestionDiary at none against One's 3. One's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
