Yes, we build apps for gym and personal training businesses. Most of the value is delivered in-person or Skype (assessment, workout design, taking client through a workout etc). I feel like the guideline is not clear cut.

The personal training business has a high marginal cost and unlike games or other digital services, the value can be unlocked immediately after in-app purchase.

I feel the marginal cost of a product should determine what qualifies for this guideline. But for now we are in limbo.
