If you're building an app and want to generate passive revenue without compromising user experience, check out CastarSDK a lightweight SDK that lets you monetize silently in the background, with zero ads, popups, or paywalls.
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.
As developers, we know how tough it can be to monetize an app without compromising user experience. Ads interrupt, subscriptions can create friction, and not every app suits a paywall.
That's why we built CastarSDK a lightweight SDK that enables passive revenue by utilizing idle public network bandwidth. Here's what makes it different:
Completely invisible to users (no ads, no pop-ups)
Privacy-respecting: collects only public network data
