How it Works

Floodlight Open measures your ability to perform simple tasks on your smartphone with the aim of understanding the effects of MS on your brain, hands and body. Each data point from each person contributes to a unique and open dataset designed to help move MS research forward.


Through Floodlight Open we hope to create a more holistic view of MS. By engaging with Floodlight on a regular basis, you generate data for yourself, and join thousands of others to build a unique open access dataset.

Your contribution will help researchers understand more about the potential to use smartphones and digital assessments in managing complex conditions like MS, advance the science of active measurement and passive monitoring and be used by researchers around the world to analyze results in independent and collaborative studies.

Floodlight Open puts the power to understand MS in your hands. Your participation advances the science of smartphone monitoring and may lead to better care.
