Kairo is a weekly journal you keep only with your close friends. Every week, Kairo gives you one small prompt. Talk to a stranger. Get lost on purpose. Take the long way. Start before sunrise. Each one asks for a little courage: go somewhere you wouldn't have gone, say yes when you'd usually pass. You answer it in postcards, a photo from your real week with a few words on the back. Then nothing happens. Nothing your friends make is visible until Thursday, when everyone's week is revealed at once. One quiet moment where you see how the same prompt lived differently for each of you. By default there is no audience. Your Kairos go to the handful of people who already matter to you and nobody else. If you ever want more than that, you can turn on World and see how strangers answered the same prompt. It stays off unless you choose it. Kairo is small on purpose: • One prompt a week, written by hand. Never AI, never generic. • Up to three postcards a week. A finite, deliberate set, not an endless stream. • Camera-only capture. The moments you actually lived, not your camera roll. • A Thursday reveal that turns an ordinary week into something you kept. Make the day count. ## Key features - Weekly journaling prompts - Postcard photo and text entries - Private sharing with close friends - Simultaneous reveal of entries - Camera-only photo capture - Optional public sharing ('World') ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/kairo-postcard-journal/id6788220408/reviews.md ### 5/5 — So aesthetic *2026-08-13* This app is so easy to use and understand and the concept is really nice and aesthetically pleasing! ## Frequently asked questions about Kairo ### What is Kairo?
