What does it do?Just open up the app when you need to enter a new number, pass it to your new future best friend, and as they enter their contact info, the app will snap a pic with your phone's front-facing camera, putting a name with a face forever. And assuming that you don't want the app alerting your new peer that their photo is being taken whether they like it or not, you can turn on "stealth mode," which is creepy, yes, but also helps make sure you don't call a relationship before it even starts.
Why do we like it?
Rarely do we take the time to assign photos to new contacts. What's more, it's pretty off-putting for someone you just met to command you to smile as they snap a pic for posterity. This way, you can appear to be a normal human being and still make your name/face flashcards to prepare for the next meeting. Everyone wins. The only downside is that the app doesn't work with the Android contact forms, so when your new friend is entering their number, they'll see the word "NumberSnap" above the entry lines. Chances are, though, that if you're both drunk or overwhelmed with a number exchange, no one will even notice. Hopefully.
