I make All Clear Weather, an innovative weather app for Android that can run multiple experiments, like using sensor data from devices or even photos of the sky as weather data. Also has a focus on clear communication of weather data! US-only for now.
Weather apps in 2018 are a wreck. Most are ad-filled, few offer any innovations and the potential is unlimited. Devices even have weather sensors! What modern tech frustrates you because it isn't being used right? What futuristic apps could be built but nobody has?
