Read full description

Lucidly collects health readings while you are sleeping via the watch. The readings are evaluated using artificial intelligence to determine when you have entered rapid eye movement (REM) of your sleep cycle. When REM is detected, the watch will alert you by triggering tactile and or audible signals. The user can attempt to recognize the signal in their dreaming state, or wake up and attempt to reenter REM via any lucid dreaming induction method of choice. Lucidly is the first and only application that specifically targets this phase of the sleep cycle using health readings in combination with machine learning and haptic signaling. The application works well and supports WILD, WBTB, DEILD and DILD induction techniques, and is available in two operating modes: Inference (REM detection and alerts), and hypnagogic (periodic haptics for sleep entry). Lucidly integrates with Apple's health kit for functionality. User permission is required to read and write data. REM prediction is performed by neural networks while the application is in session and the user is asleep. Lucidly has an overall accuracy > 80%. REM inference is an approximation and results may vary. Familiarity and some experience with lucid dreaming induction techniques is recommended before subscribing. Lucidly provides the following features: - Real time REM prediction with auto shut-off tactile and audible signaling. - REM stage determined by artificial neural networks (AI). - Greater than 80% model accuracy. - Two operating modes: Inference and hypnagogic. Modes can run in tandem or independently. - Ability to adjust prediction thresholds, haptics, session and alert durations. - Analytics and charts generated for each session with notification timestamps. - Seamlessly integrates and displays Sleep App metrics. - Ability to playback sessions and test different settings against REM detection models. - No registration required to use the application. - No personally identifying information is collected. - Subscriptions are auto-renewable and can be cancelled any time. - All plans include a FREE 7-day trial. =============== IN-APP PURCHASE: Monthly: $5.99 Yearly: $39.99 ($3.33 / mo) - Payment will be charged to iTunes account at confirmation of purchase. - Subscriptions automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. - Account will be charged for renewal within 24 hours prior to the end of the current period, and identify the cost of the renewal. - Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase. =================== BEFORE YOU SUBSCRIBE: Lucidly requires Apple Watch for functionality.
