Hate when your phone rings when you are flying down the freeway in heavy traffic? Not Now Lite is the application for you. Just launch Not Now Lite. If you are driving at 23 mph or faster, Not Now Lite will mute the ringer on your phone. If a text message arrives, Not Now Lite not only mutes the ringer, but sends a text message to the sender telling them you are currently driving. Not Now Lite works best in areas with good GPS satellite visibility. This app does not need or use a connection to the internet. Not suitable for tablet or wearable use.
