The idea is simple: most of us have shelves full of books we've already finished. Okudum lets you list books you've read and request books other readers have listed. You never pay for the book itself — you only pay the cash-on-delivery shipping fee.

It runs on a simple points system: everyone starts with 2 points, requesting a book costs 1 point, and sending a book to someone earns you 1 point. That keeps sharing balanced and fair.

The app is in Turkish and available on Google Play: https://play.google.com/store/apps/details?id=com.okudum.app (or just search "okudum" on the Play Store).

I'd love feedback from other developers on the idea, onboarding, and how to grow a small community-driven app.
