You can use an Excel Spreadsheet or a Google file as input. Also you can link web services to your app.
At the end of the creation process of your first app Open as App will ask you to add your email address and a password. This is your log-in information for your next session with Open as App. As an admin you are able to create apps, share these apps and manage these apps.
If you have so far only been using apps you can register by visiting Open as App and click on the registration button. This way your portfolio will not be lost when moving the app to another device or can be accessed on other devices, too.
