DriveMode is a safety minded app targeted towards "texters", but usable by anyone with an iPhone or Android phone. The concept is rather simple, yet the UI had many nuances we had to explore. Essentially, users turn it on and once they are driving over 15 mph, we auto-reply to inbound text messages with a custom message (Ex. I am driving right now, I'll give you a ring once I am in a better spot."). It also directs phone calls to voicemail.
