Monitor which websites stress you the most. Misü is a desktop app designed to measure users’ moods while online and notify them if particular websites are triggering stress hormones. Once installed, Misü takes photos of users periodically while they’re on the internet. The app then uses an algorithm to analyse the images and estimate whether the websites the user has visited is having a positive or negative impact on their mood. Armed with this knowledge, users can then choose to avoid sites that tend to make them tense or sad.
