"Pixntell is an iPad app for quickly creating simple narrated photostories. To create a story using Pixntell all that you need to do is start a new project, select some images, place them in order, and then start talking about each of your pictures. You control the timing for each image. If you want to talk about your first picture for twenty seconds, your second picture for just three seconds, and your third picture for fifteen seconds, you can do that. When your project is complete you can upload it directly to YouTube, share it on Facebook, or send to friends via email."
