FontType app for iPhone and iPad
FontType helps you to discover fonts in your phone.
When designing an application, you will sooner or later need a list of available fonts and see what they look like. Often you need to show them to other people, too. FontType displays you all available fonts together and separately - and allows you to email a plain list of names or real images using the font style.
Features e.g. alphabetical listing of all system fonts, search, font sample text and emailing either names or images.
