I’m working on a mobile app that could work out well either way with in-app purchases or with a subscription model.

I’m looking for data on revenue from subscriptions vs in-app purchases, but having trouble finding anything outside of mobile games.

I’m also interested in hybrid approaches like Audible with the ability to gain in-app currency via subscriptions or purchase the specific item directly.

Curious if anyone knows of any studies out there that could help guide my research and also any individual experience using each approach in your own projects.
