GoKawiilThe90's $249 Gem necklace tracks personal UV exposure in real time
The90 makes Gem, a $249 wearable necklace that monitors a user's real-time UV radiation exposure via a companion app and sends alerts when levels rise. A reviewer described using the device at an outdoor Los Angeles event, where it flagged rising UV exposure despite shade from a patio umbrella, prompting her to reassess her sun protection habits and investigate a medication-related heat sensitivity.
GoKawiil's interpretation of the reporting above, not reported fact.
The account suggests wearable UV trackers could help users notice environmental risks that aren't obvious from shade or fans alone, since UV radiation can scatter or reflect around physical barriers. It also hints at a broader shift in wearables from vanity-driven skincare tracking toward tools that may surface health issues, such as medication interactions, though the device itself does not diagnose conditions.
