Lucidly

Lucidly is an iOS app paired with an Apple Watch, requiring both an Apple watch and iOS device. It collects health readings during sleep, evaluates them with artificial neural networks to predict when the user enters REM sleep, and then triggers haptic (tactile and/or acoustic) alerts. Users can either try to recognize the signal in a dream or wake up and attempt to re-enter REM using a lucid dreaming induction method such as WILD, WBTB, DILD, or DEILD. Users can adjust thresholds, alarm durations, haptics, and other settings. The page states prediction accuracy may vary by person and night, and that the app does not guarantee lucid dreams. Lucidly offers a 7-day risk-free trial, no free tier, no registration required, and cancellation at any time.
