I'm looking for clarification on the App Store fees charged by Apple for a hardware related app. Refer to the relevant App Store Review Guideline:
When the app provides the UI for an external IoT device, and there is an annual fee charged to the user (which may be via an external link) does Apple charge a percentage?
My reading of this line is that no fee is charged.
when features are dependent upon specific hardware to function, the app may unlock that functionality without using in-app purchase.
The app only has value when receiving data from the IoT device. Intention is to charge an annual subscription, paid via external link.
I have the same question for the same scenario with an Android app.
An example of this, is the Nest Cam. The cam is bought in a store and the app downloaded at no cost. The camera works with the app on a free basis. There is an upgrade to premium storage and features paid by subscription to Nest Aware. Does Nest pay a fee to Apple/Google for the subscription? I'd expect not, as the features are dependent on the camera.
