Lumen Track

Ever wondered how sunlight affects your mood? Lumen Track lets you log your daily light exposure activities and assess how you feel throughout the day.

Record time spent outdoors, indoors in bright light, using screens, or in low-light environments. Then, rate your mood and add optional notes. Over time, the app shows the correlation between your light exposure habits and your emotional state.

Weekly and monthly trend charts provide a clear overview. A simple statistics dashboard tracks your streaks and averages. Set reminders so you never forget to log.
