Lux Alarm

Stop Oversleeping with Lux Alarm

Tired of hitting snooze and waking up late? Lux Alarm ensures you actually get out of bed by requiring light to silence the alarm.

How it works

To stop the alarm, you must get up and open your blinds or turn on the light. The app uses your phone's sensor to detect brightness; by the time the alarm turns off, you are already on your feet and ready to start your day.

Key Features

• Smart Light Detection: Uses your phone's sensor to ensure the alarm only deactivates once your environment is bright.
• Adjustable Sensitivity: Customize the required light level to account for gloomy weather or different room setups.
• Modern Interface: A clean, intuitive design based on Material Design 3 for easy navigation.
• Circadian Support: Waking up with light helps regulate your natural sleep cycle and reduces morning grogginess.
