Ludream: Lucid Dream Journal

Ludream is a calm, private dream journal and lucid dreaming companion. Record your dreams the moment you wake, practice reality checks, and learn how to become lucid inside your dreams (step by step).

Everything stays on your device. No account, no ads, no tracking. Ever.

Write down your dreams
• Capture entries fast, including voice-to-text, before the memory fades
• Tag mood, vividness, techniques, dream signs, and recurring themes
• Add reflections on triggers, meaning, and what you learned
• Search, filter, favourite, and link recurring dreams across time

Learn to dream lucidly
• 8 lucid dreaming techniques (MILD, WBTB, WILD, SSILD, and more) with clear, step-by-step guides
• 9 reality checks with instructions and reliability ratings
• Interactive training exercises and reality-check reminders
• A practice quiz hosted by Lunario to test what you know

Understand your sleep
• Track nights, dreams, lucid rate, and your journaling streaks
• See your most common dream signs and what tends to trigger lucidity
• Follow mood, vividness, and technique effectiveness over time

Built for privacy

Free to use, yours to keep
Ludream is free to download. The full dream journal, all 8 techniques, every reality check, a set of training exercises, the practice quiz, and your core insights are included at no cost.

One optional purchase unlocks the rest: in-depth articles, more training exercises and meditations, deeper insights, and extra quiz topics — plus anything added to those features in future updates. It's a single one-time purchase, not a subscription. Unlike most dream journal apps, you buy it once and it stays yours.

Sweet dreams.
