Fav_Call app for iPhone and iPad
FavCall is a handy app to store your favorites from your phonebook and call them (or send a message) with one tap.
It has 9 preconfigurable buttons.
Each of them can be preset with an entry from the phonebook with a number, a name (can be edited to a nickname) and an image by a long tap on the button.
Two buttons on the toolbar switch between phone call and messaging.
