The product

Spindle is a stress-relief fidget spinner game that pairs simple, satisfying physics with a real backend economy: players earn rewards for inviting friends, tracked through the Play Install Referrer API and settled server-side.

It's a small game with production infrastructure — Node.js + PostgreSQL reward ledger, AdMob monetisation, and an API designed to be cheat-resistant.
