Paywalls are the critical part of mobile apps monetization. Adapty serves thousands of paywalls to millions of users. In this talk, I'll share:

1. How we built the paywall rendering on the SDK

2. Why we went native over HTML

3. How we managed to deliver sub-second paywall loading time for the 97th percentile across 100m+ requests per day without spending hundreds of thousands on the infrastructure

We'll also share paywall insights that help increase conversion

Quantifying design system adoption is never as straightforward as it seems. What actually “counts” as a component, and how do we measure coverage across an experience? While many teams try to put numbers to these questions, the reality is messy: definitions are fuzzy, ownership is unclear, and metrics often fail to capture the whole picture. In this talk, we’ll explore the challenges of measuring components in design systems — from coverage metrics to questions of responsibility — and discuss why a shared understanding is just as important as the numbers themselves.

Discussing how designing components that are "selfish" leads to longer lasting more flexible components.
