Can I use my App on many devices? (educational institutions, other organizations)
1. You need to buy one license for an App for each iOS device if that device is used by multiple users or one license of an App per user if that user is using multiple devices.
2. Your organization can authorize a single iTunes account on up to 5 computers. Your organization can thus store the purchased Apps on up to 5 computers and synch iOS devices from those 5 computers. There is thus no need to buy an App multiple times just because your organization wants to store and synch that App from a single employee’s laptop and desktop computer.
You can authorize a single computer for more than one iTunes account and then sync apps from up to 5 iTunes accounts to your iOS devices. On the iOS devices in the Store section of the Settings app you can log out of one iTunes account, log into another iTunes account and then purchase or redownload Apps using the App Store app. It is thus possible to put Apps on a employee’s iPhone that were purchased with the employee’s personal iTunes account as well as those purchased with a company iTunes account.
