Sleep Tracker

Sleep Tracker is a smartwatch application built with ArkTS, designed to help users wake up more naturally and peacefully. Instead of using loud sounds, the app relies on gentle vibrations to wake the user at their set alarm time. After waking up, the app provides insightful reports based on the user’s sleep session, including:

• Total sleep duration
• Sleep efficiency
• Estimated dream (REM) time
• Number of times the user woke up during sleep
• Analysis of whether the number of wake-ups is within a normal range

The goal of the app is to improve users' sleep quality, promote better wake-up experiences aligned with natural sleep cycles, and increase awareness of personal sleep habits.

Use Cases

• Vibration-Only Alarm: Wake up naturally with silent vibration, avoiding the stress of loud alarms.

• Sleep Reports: After each sleep session, receive a detailed summary including total sleep time, sleep efficiency, and more.

• REM Estimation: Get an estimated duration of your dream (REM) phase to better understand sleep quality.

• Wake-Up Frequency Analysis: Track how many times you woke up during the night and whether this count is considered normal.

• Minimal, Smartwatch-Optimized UI: Designed specifically for smartwatch interfaces using ArkTS, with smooth performance and intuitive interaction.
