Is there an omegle app for the iPhone 4 that has video chat available?
The closest app we could find to Omegle that allows you to video chat with strangers on an iPhone (3G, 3GS, 4, 4S, or iPad (2 or later) is called Live Area.
Live Area uses your GPS coordinates to find other users of Live Area and displays stars for each one it finds. You can then click on their star to watch their video feed; if you find them interesting you can send them a request to chat with them through video chat.
You have the option of viewing people just in your local area, or opening up the area to find people far away from you, even in other countries.
Video chat has become very popular in recent years, and many are forgoing traditional dating sites in favor of sites that let people video chat with other random people until they find someone with mutual interests.
