Lucidly will collect 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 haptic signals. Lucidly is the first and only application that specifically targets this phase of the sleep cycle using health readings, machine learning, and auto shut-off haptic signaling. The application can be used to support various lucid dreaming induction techniques, and is available in two modes: Inference (REM detection and alerts), and hypnagogic (periodic haptics for sleep entry).

Lucidly integrates with Apple's health kit for functionality. Authorization is required to communicate with the Health App Store to read and write data. REM determination is performed real-time by pre-trained neural networks while the application is in session and the user is asleep. REM inference is an approximation, with a model accuracy of 88% (REM stage Recall .94, Precision .75). Lucidly offers the ability to adjust various settings to customize your experience.

Privacy is at the forefront of our application. Lucidly provides the following features:

- Real time REM prediction with auto shut-off haptic signaling.
- REM stage determined by trained artificial neural networks.
- 88% REM detection model accuracy (REM stage recall 0.94, precision 0.75, and F-score 0.83).
- 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.
- 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.
- Derived analytics are stored on the device and never submitted to external services.
- Subscriptions are auto-renewable and can be cancelled any time.
- All plans include a FREE 7-day trial.


Monthly: $5.99

Familiarity and some experience with lucid dreaming induction techniques is recommended. Lucidly requires a companion Apple Watch and application for functionality. This application will not work without a paired Apple Watch and installed companion lucidly watch application.
