Yes, this is possible thanks to Apple Family Sharing.
NavimetriX supports Family Sharing. Your Premium subscription can be shared with up to 5 family members, each with their own Apple ID, as long as they belong to your Apple Family group.
Three solutions depending on your situation:
- Apple Family Sharing (different Apple IDs within a family) — Set up Family Sharing in Settings > [your name] > Family Sharing, then add your family members. Once added, they will automatically have access to your NavimetriX Premium subscription on their own Apple devices. See Apple's help: Set up Family Sharing.
- Same Apple ID on several devices — If you want to use NavimetriX Premium on several of your own Apple devices (iPhone, iPad, Mac), sign all of them in with the same Apple ID (the one that purchased the subscription).
- To use NavimetriX Premium on other platforms (Android, Windows, or Linux) — Create a NavimetriX account in the app after subscribing, then sign in to that same account on your other devices. The subscription will be recognized regardless of the platform.
To create your NavimetriX account, see the FAQ "How do I log in to my NavimetriX account?".
