## Application functionalities



- Determines chronotype based on the provided user info

- Calculates optimal sleep time based on the provided user info and calculated chronotype

- Monitors daily habits

  - Alcohol consumption before sleep

  - Caffeine consumption before sleep

  - Bright light exposure before sleep

  - Intense physical activity before sleep

- Calculates daily bad habits scores

  - Based on the habit intensity and proximity to the optimal sleep time

- Tracks brain activity

  - Determines when the user is awake

  - Determines when the user falls asleep

  - Determines sleep stages that the user is going through during the sleep

    - NREM stages 1-4

    - REM stage

  - Detect wakeup

- Sleep efficiency calculation

- Daily habits recommendations

- Detection of the most common sleep disorders

  - Somnambulism detection

  - Insomnia detection

  - Narcolepsy detection



## Technology
