Shut App is a simple tool that proves extremely helpful for communication in any loud environment, be it an airport, busy streets, big music festival, or a bar on a Friday night. It makes an already big text (so it's harder to make a typo) EVEN BIGGER.
Use it anytime you want to talk to someone at a distance, don't know how to pronounce something in local language (say, an address in a cab), or just don't feel like talking.
Agree on a background colour with your friends and show them where you are if you get lost in a crowd.
