Per-app plan
The per-app plan is the newest type of licensing to be introduced by Microsoft and has been a response to the community suggesting that paying for a per-user plan for all users, when we only have one or two apps, is too expensive. Therefore, the per-app plan allows you to license just a single app for all the users who are part of your organization. The advantage of this approach is that you are still able to unlock the full capability of PowerApps for all the creators and users who are working with this app.
The cost of the per-app plan is $10 per user, per app, per month. It should be understood that, in the context of this license, an app allows you to create two apps, which can either be two canvas apps, two model-driven apps, or a mix of the two.
