Maestro Pro
Use your licence on up to 3 devices
A licence bought on the website works on up to 3 devices: for example an iPhone, an iPad and a Mac. Enter the same key on each one. A device is counted the first time it is used with the key, and the key is checked each time the app is opened.
If you try a fourth device, Maestro Pro says the licence is already in use on 3 devices. Remove a device you no longer use to free its place, then enter your key again.
A device that has not been used for 60 days stops counting automatically. If you delete the app and install it again, that counts as a new device until the old one is removed or ages out, so remove the old one if you reach the limit.
Education licences, bought for a whole organisation, have no device limit. See Buy for a whole organisation.
