Drunk Dial NO! is an app that hides contacts' phone numbers and email addresses for a period of time, ranging from 1 to 48 hours. It's an ultimately useful app for those who like to go out for a night on the town without worrying about drunk dialing. Developed by Explore Fun Inc, it's a full version app that is available on iPhone.

Drunk Dial NO! is suitable for people who have contacts on their iPhone that they should not phone or email after a night out, such as ex-partners, parents, or bosses. The app can hide an unlimited number of contacts and block incoming calls for the time set. It also has a new feature that allows users to send themselves a message up to 48 hours in the future to prevent making a dreadful mistake. Drunk Dial NO! is easy to use and looks great on Retina displays.
