Do you think the paper-based business-card era is over?
Forgot someone's name? Awkward situation?
Nitomeyo to the rescue!
Nitomeyo is a Bluetooth-based discovery application which tracks all your interactions and keeps them on the device and cloud. This way you can still meet people when your web connectivity is down but Bluetooth still works. As soon as you turn on the internet, all your interactions will be synced locally!
When a person with the app is closer to you than 10 meters, then he/she shows up in your "Who is around" list alongside with the credentials he/she wished to share such as picture, name, phonenumber. It gets even better - it also has a "Add as a friend in Facebook" button using which you can add your new pal to your friendlist. No hassle!
