Puppet Pals allows children to animate, and share their own stories. Simply press the record button, move your characters onscreen, and tell your stories. The Puppet Pals App is free and comes with Wild West set of characters. For more scenes and characters you have to make in-app purchases of about 59p per pack, or you can buy a Directors Pass for £2.39 with all the character packs included.
It’s worth getting the directors pack as this lets you use your own images as characters and backgrounds. This makes it even better for use in the classroom. Children could act out scenes between famous people that they are studying in class, or insert themselves into the story. There’s a built-in editor which lets you cut out people from a photograph so that they work in the app.
