Yes, you’ll need one Name List subscription per Entagged because the subscriptions are activated based on serial number. This system has some great benefits: you can simply plug the Entagged into any camera, open the app on any phone and start shooting, without needing to verify the subscription or logging in anywhere. So if you use different phones/tablets with the same Entagged, the feature will be usable on all of those devices (meaning anyone on your team can download the app, connect and shoot with the Name List). If you use multiple Entaggeds from the same phone, and only have one subscription, only the one Entagged that you unlocked will have that feature available.
