Pages

Create and manage Pages templates on iPhone
If you create a document that you want to use again as a model for other documents, you can save it as a template. Creating your own template can be as simple as adding your company logo to an existing template, or you can design a completely new template.
You can add your custom templates to the template chooser, save them as a file to share with others, and use them in Pages on your Mac or iPad. Custom templates that you create on your iPhone are grouped in the My Templates category of the template chooser and are shared across all your devices.
