Gatorade Sports Science Institute (GSSI) Labs App for Hydration Study

This study is looking at how well the Gatorade Sports Science Institute (GSSI) Labs App works for checking hydration levels from home. Researchers want to see how easy it is for people to use the app to report their hydration and how well it measures hydration using a special camera technology called transdermal optical imaging (TOI). You can join if you are between 18 and 65 years old, can read and write English, are not pregnant or breastfeeding, and own an activity tracker that you wear daily. The study aims to understand how engaged users are with the app and if it's practical to collect hydration data this way. The current status of the study is unclear.
