Most monetization models rely heavily on in-app purchases or ads but the truth is, only a small percentage of users ever pay or click.
What if there was a way for every single user to contribute to your app s revenue, without changing their experience at all?

That s what we built CastarSDK for.
It helps developers generate passive income from their entire user base, including free users, by utilizing idle network resources all without ads, popups, or disrupting the app s flow.

If you're interested in new ways to build a sustainable app business (especially if you have a large free user base), check it out. Would love to hear what you think!

CastarSDK is a lightweight SDK that enables passive income by sharing idle public network resources. It's designed to be invisible to users, with minimal impact on app performance and full compliance with privacy standards.
