Stability aims to simplify the mood health process for everybody. Simplistically, as people get more intertwined with their phones, there needs to be a middle-man keeping people in check, because our devices can drastically alter who we are as people. Stability is that middle-man. By taking a simple photo and getting a mood recognition, Stability sends timely notifications on ways to improve your mood, giving you the "wake-up" call non-invasively. It aims to streamline this mental-health actualization process, and is an alternative to ensuring that people understand their moods better.
