Muv

Muv is a phone add-on that transforms bike bell rings to help you be heard on streets. User attach it to their phone and fidget it as they would normally use them. The sound gives off a warning signal to the people around them. Imagine if you could browse Instagram feed uninterruptedly while on class break to the crowded dining hall. Imagine finishing an article on your way to work at a crowded sidewalk and being assured that no reckless people will bump into you.
