AI REM detection on Apple Watch to help you become lucid in your dreams
Overnight Apple Watch health readings are evaluated by artificial neural networks to estimate when you enter REM sleep.
The watch vibrates or plays a sound when REM is predicted, giving you a cue to recognise the dream state from inside the dream.
Adjust thresholds, alarm duration and haptics so the detection logic matches your own sleep patterns and results.
Designed to work with WILD, WBTB, DEILD and other common lucid dreaming induction methods.
