I built a mobile app called Lucidity (luciditydreams.com) aimed at helping people have their first lucid dream:

iOS: https://apps.apple.com/us/app/lucidity-lucid-dream-journal/i...

Android: https://play.google.com/store/apps/details?id=ch.b3nz.lucidi...

Started building it 14 years ago after reading an article about lucid dreaming in my favorite science magazine, and no other apps out there existed to assist you with reality checks and the different induction methods. Recently added a 7-day lucid dreaming journey to guide you to your first lucid dream. I worked with lucid dreaming researchers for the program's content.

Feedback welcome!
