# Copy of Apna RSS Hit 21,000 Users: Scaling Flutter for a Content-Heavy App

**[Medium](https://daily.dev/sources/medium_js)** · 5 min read · 0 upvotes · 0 comments

## Summary

A developer shares five concrete performance lessons learned scaling a Flutter RSS reader app to 21,000 users.

The post closes with a reusable performance checklist for any list-heavy Flutter screen.
