Q. Can I use a single KineMaster Premium subscription for Android and iOS?
No, you can't.
You can use one KineMaster Premium subscription on up to 5 devices, but they must be either all Android or all Apple devices.
If you purchase a KineMaster subscription through the Google Play Store on an Android device, you can use it on up to 5 other Android devices (and Chromebooks), but you can't activate your subscription on iOS devices or M1 Apple products.
Similarly, if you buy a KineMaster subscription through Apple's App Store on an iPhone/iPad, you can use it on other iOS devices and M1 Apple products, but you can't use it on Android devices or Chromebooks.
