Leave your memories in a five-dimensional space within a black hole. Write your story among the stars. Beyond the black hole, record your day in five dimensions. Tesseract is a journaling app inspired by the film Interstellar. Keep your most meaningful moments inside an immersive 3D space, and return to them anytime. Your journal is no longer just a date. It becomes a coordinate in a universe that's yours alone. ◆ A 5D tesseract space, memories on a bookshelf Each entry lands on a 3D bookshelf, one volume at a time. Turn through past and present like pages, and meet the person you were that day. ◆ Words and photos that come alive Gentle animation brings your writing and photos to life. Pick a mood and an entry type that match how you feel, and shape a page that's unmistakably yours. ◆ Write it or say it On days when typing feels like too much, just speak. Your voice turns into text instantly, so you can recall your day and finish an entry with ease. ◆ Privacy by design Everything saves safely to your personal iCloud, with no account needed. It syncs automatically across your devices, and only you can see what you write. ◆ Journaling Suggestions Connected with Apple's Journaling Suggestions, Tesseract hands you a fresh prompt every day. With ideas drawn from your photos and activity, you can start writing without wondering "what should I write about?" Features - Immersive 3D tesseract interface - A range of moods and entry types - Type or dictate your entries - Unlimited photo storage - AI-powered writing prompts - Automatic iCloud sync - Passcode lock - Markdown import and export - Multiple font options - Multilingual support Start your own journey through time in five dimensions, today.

Past journal lost

I like this the UI design, it could be a good journal app, however have faced two times my journal gets lost. The first time happens in the beginning of 2025, I suddenly found out that all my 2024 journals disappears. Very frustrating.The second happened just now, I wrote something in the morning and switched to some other app. In the evening I found what I wrote gone. I have to make a decision to move to other options this time. If it keeps lost my journals it is not usable.

The UI design is stunning, from the subtle gloom of the cards to spacial text-image composition, everything is just gorgeous. The interaction is smooth and stable, very thoughtful on user experiences.And the fact that this app takes up only 6MB is phenomenal. Hope for customizable theme (like background/text color) and PDF export.
