About

Lunaria

Features
Read full description

Lunaria is a quiet place for dreams. Press a single mark of remembering before the morning forgets it. Open the app, save the fragment that came back, and close it again before sleep slips away. — A QUIET RITUAL Tonight tab, one tap. The cursor lands in an empty field, the keyboard is up, and the page is dimmed to spare your eyes. Title is optional. Notes can be a sentence or a page. Tag what came back: stairs, mother, water, light. Mark a mood from a soft palette of eight: veiled, neutral, uneasy, luminous, tender, turbulent, hollow, sacred. KEPT GENTLY Browse a year of dreams by date, by tag, by lucid moments, or by recurring symbols. Each entry opens like a letter — title in serif, body to read at your pace, tags below. PATTERNS APPEAR WITH TIME After a few weeks, recurring themes and tag frequencies reveal themselves on a single quiet page. A heatmap of nights kept; a chart of words that come back; the symbols that repeat. YOURS, NEVER UPLOADED Lunaria lives only on your phone. There is no account, no cloud, no AI uploads. We never read your dreams; no service does. If you want to back them up, an encrypted export with your own passphrase is available — only you can unlock it. LOCALISED FOR YOUR HANDS Available in nine languages: English, German, French, Spanish, Portuguese, Japanese, Korean, Arabic, and Simplified Chinese. Right-to-left script handled with care. WHAT'S INSIDE • A 180pt seal-button to begin a dream — single-tap, unmistakable in the dark. • A library of every dream you've kept, with date / tag / lucid / recurring views. • Patterns: a yearly heatmap, frequent tags, and recurring symbols. • Six themes: Heirloom Silver, Moonless Indigo, Brass Dawn, Sage Linen, Mulberry Velvet, Aurora Mist. • Reality Check reminders — silent, no sound, just the gentle nudge. • Encrypted PDF and JSON export with PBKDF2 + AES-GCM. Your passphrase, your file. • Four haptic intensities, from off to heavy. Default is light, for nights. LUNARIA ANNUA The moon flower, with translucent silvery seed pods like coins. In Victorian flower language, lunaria meant 'sincerity'. We took it as a name.
