Much like Instagram, Viddy provides a number of filters that you can apply to your videos. You can control the intensity of the filter and even use a pre-supplied soundtrack; then tag the clip with your location and a description. Viddy easily syncs with Foursquare, Facebook and Twitter and displays your videos and those of your friends in a continuously updated feed.
The app is free to use and hit the iOS App Store today. Give it a spin for yourself.
