The LYS Apps
LYS Collect app
LYS Collect connects to both LYS Button V1 and LYS Button PRO, making it easy to gather light data from multiple participants on a shared device. It is ideal for distributed, large-scale studies and for projects where participants do not have their own smartphone.
LYS Track app
LYS Track connects each participant to their own LYS Button V1, giving them clear insight into light intake, chronotype, sleep and energy patterns. It is ideal for studies that need a more engaging participant experience together with access to raw data through the LYS Data Platform.
The LYS Button V1
Continuous light and movement
Used in leading research in the field of sleep, light and chronobiology accross the world, the LYS Button allows for seamless and simple tracking of light exposure. The wearable light sensing device also tracks movement with the inbuilt accelerometer. Easily clipped to everyday clothes, the LYS Button is a truly human centric tool to measure light intake with study participants.

What researchers say
“LYS is an innovative design which shows how the daily patterns of light influence our sleep-wake cycles in a vibrant, user-friendly visual display. Their data services provide great potential in assisting research on circadian rhythms, health and sleep in the future. It is definitely a pleasure to work with such a caring and enthusiastic team.”
