Many people keep a regular schedule. With Hush, tell your phone your normal schedule, and Hush will mute the ringer when you shouldn't be disturbed. Never again will your phone ring out loud at work, school, or any other time when you are busy.
Hush is unique in the market because it focuses on preserving battery life. It's a lightweight application that puts less drain on the battery than if you were to try and manage the ringer yourself.
