An app that seems simple in what it does at first but really saves you from some awful moments, Locale changes your phone’s ringer settings based upon where you are located. If you are stuck in an important class or meeting, it will automatically know, and adjust your ringer. What started out as a mere embarrassment solution got more popular as people loved being able to use the GPS features on their phone so it would know when they couldn’t be bothered. Another great feature is having the VIP caller list that always lets certain people get a hold of you no matter what type of business you’re attending to!
