Can I use more than one iOS device?

Yes. Just like any other iOS application, it is linked to your Apple ID. Your Apple ID can be bound to up to 10 iOS devices, according to Apple. Your iPhone, your iPad, your child’s iPod Touch might all have apps bound to your Apple ID and thus be able to run any app you have purchased.

However, Family Sharing does not support the sharing of in-app purchases such as the Simple Service as they are tied to your Apple ID. There are three ways to share your Simple Service in-app purchase with your family members or guests. The first two require designating a hub that is an always-on, dedicated iOS or tvOS device (or runs on macOS in the background).

  1. Simple Control will share your in-app purchase via your Simple Control account paired with a hub and associated to your specific configuration. To do so, you must be signed in to your Simple Control account when making the in-app purchase or when selecting “Restore Purchases” in Settings > About. You must be paired with a designated hub or do this from iOS on your hub if you run it on iOS. Once the purchase is shared as part of your configuration, all paired devices for your hub will share that subscription. This method applies to the owned configuration associated with that Simple Control account.
  2. If you subscribe to Simple Service Unlimited, you can add user profiles to your home. Each family member needs a free Simple Control user account. With their own Simple Control account they can then be added as Guests to your home. This provides them access to your configuration, activates your Simple Service for them while controlling your configuration, and prevents them from editing the configuration. This is a more refined version of the above method that provides access control and permissions.
  3. For environments that choose not to designate a hub device, you may change your iOS device’s Apple ID temporarily and then install Simple Control from the App Store. Then, select Settings > About > Restore Purchases. Note that you do need to re-authenticate your Apple ID password on a regular basis to use this method even if it is not the signed-in Apple ID for the device configured in the iOS Settings application under the App Store tab. So, this is only viable in a typical family scenario. The App Store also places additional limits on this so that it can only be performed a limited number of times. Here is a link to Apple’s support article on this topic.
  4. In some cases without a designated hub, multiple subscriptions may be the simplest solution. Any environment that wishes to synchronize configurations between multiple devices will need a hub anyway, so we recommend the first or second methods above.
