I've been developing this app for a few months. This iPhone app (also Android app) allows you to send private video messages to your friends if you have their numbers in the phone book. To send a message, hold the profile picture of your friend (start recording), and then release it (stop recording and send the message). To watch a received video message, tap the profile picture of your friend.
This app is particular useful in the following situations: - You have some close friends/boyfriend/girlfriend that you really want to "talk" to each other - You have some friends who live very far away, maybe oversea, and you want to see and hear each other. Facetime doesn't suit because you are in different timezone - You are lazy to type :-p
The app requires signup with username and password (this will be used when you move to another phone) and SMS phone verification (this is to make sure you can find your friends and vice versa via phone numbers). Of course, you need to tell at least one friend (boyfriend/girlfriend? :-p) to install the app so that you can send message to each other.
I keep improving it and make it more useful. I appreciate your feedback. Any bug reports and feature requests are welcome.
