About

Gratitude Journal Diary

Features
Read full description

Good things happen every day. Most of them are gone by the evening because nobody wrote them down. Gratitude Journal Diary is where they go. One line, ten seconds, and the day is kept — the coffee that was exactly right, the message that arrived at the right moment, the walk that fixed your mood. WRITE IT DOWN, ANYTIME An entry takes one line. Write as many in a day as you like: 07:00 and 22:40 are two separate moments, not one diary page. Tag how it felt, mark the ones worth keeping, and get on with your day. UP TO TEN PHOTOS AN ENTRY Attach what you actually saw. Photos open instantly in your journal, because a small version is kept ready for the list and the full one for the moment you tap it. A STREAK WORTH KEEPING Every entry lights up its day. The calendar fills in behind you, the streak counts forward, and the daily reminder stands down the moment you have already written — it never nags you for something you have done. THE FOCUS ROOM A reflective companion that has read your own journal. On a heavy day it asks how you are, and then answers with the bright days you wrote yourself — your words, quoted back to you, not generic advice. It is there for reflection, and it is not a therapist, a doctor or a crisis service. SHARE ONLY WHAT YOU CHOOSE Your journal is private. If you want to share one moment, post that single entry to your friends' timeline — always under your name, your choice every time. Friends can cheer it and comment. Everything you did not post stays where it was. SEE THE YEAR YOU HAD Mood over time, your longest streak, the months you wrote the most, and "on this day" bringing back what you were grateful for a year ago. ABOUT THE AI Focus Room replies are produced by an AI model. Your message, a short summary of your journal, and — when the answer needs them — the text of your own entries are sent there to write the reply. Only your own entries are ever sent, and your photographs are never sent to the model. There is a limit of 60 Focus Room messages a day. PRIVATE BY DEFAULT The app has no advertising and no tracking, and it never asks for your location or your microphone. You can delete any photo, any entry, any post, or your whole account from inside the app. Privacy policy: https://gratitude-journal-diary.vercel.app/privacy Terms of service: https://gratitude-journal-diary.vercel.app/terms
