Emotion diary. Every leaf is a diary entry, and leaf colors represent your mood. Grow your tree journal to log daily feelings and thoughts. Customize your tree. Grow your personal emotion tree with every journal entry. Every note you write becomes a leaf, colored by your mood. When you trigger AI reflection, new gentle flowers bloom on your tree. Build multiple unique trees for different chapters of your life. Each branch stands for a life theme: work, study, family, romantic relationships and more, to sort your memories clearly. Trace your inner world with the timeline map view. Look back and observe how your feelings change across time. Take full control over your privacy. Switch freely between unencrypted or password‑protected mode. Your password never leaves your device — it is stored locally only. Face ID unlock is supported for fast, secure access. Your journal entries are safely synced to your own iCloud with local‑side encryption. Only you can view your private memories. Jot down your feelings, thoughts and daily moments freely. Whenever you want deeper self‑observation, tap for soft AI‑powered reflection. In‑app purchase unlocks extra AI reflection quota. No mandatory account login required. Important note: This is a personal journal and self‑reflection tool only. It is NOT a medical or psychological therapy service. All AI outputs are for reference only. Please turn to professional mental‑health support if you are in need.

Ratings & Reviews

This version is a localization and bug-fix update. There is no new paid feature and no change to how Mate credit is sold. **Localization** The app includes nine languages (en, zh-Hans, zh-Hant, ja, ko, es, de, fr, pt-BR). Users can set the in-app language in Settings. UI copy, onboarding Continue, the local unlock screen, the Mate buy button, and home quotes follow that setting. No account is required. **Bug fixes** - Add photo on Record Moment: camera and library. - Browse Moment: tap a photo to enlarge, pinch/double-tap to zoom, close with X. - Home bottom bar no longer stays shifted after keyboard, camera, or the photo viewer. - Unfinished Moment text is kept if the user leaves the editor and comes back (still discarded only if they choose Discard). - Device lock appears over the editor, not under it. - Custom mood editor folds closed without a flash. - After using the camera, journal text stays on the light theme.
