Everdream is a free iPhone app developed by Sandratra Razafindralambo, designed to assist users in achieving lucid dreams. The app offers a unique feature called REM Sleep Alarm, where it monitors sleep stages and alerts users during REM sleep to enhance dream awareness. Users can customize the alarm with personal audio, volume, vibration patterns, and repetition settings. Everdream allows customization for REM sleep detection preferences, focusing on specific REM cycles and choosing alarm timings within a cycle.

Moreover, the app includes a Dream Journal feature with a user-friendly text editor for recording dreams, rating lucidity, and tagging dream signs. It also provides reminders for Reality Checks throughout the day to aid in lucid dream induction. To ensure data privacy, Everdream offers passcode protection with options for fingerprint or facial recognition unlocking on supported devices.
