Founder

I'm Devion Villegas, founder of App Zero Labs, LLC.

My work covers web and mobile apps, along with the APIs and data systems behind them. App Zero Labs is where I'm building TCGComps, our platform for trading-card collectors.

More about my work

Our platform

TCGComps

App Zero Labs owns and develops TCGComps, a trading-card platform for web and iPhone. Collectors can research cards, compare sales and price history, organize their collections and plan trades.

The website puts those tools in the browser. The native iPhone app adds card scanning and is still in development. We haven't announced an App Store release date. The product page shows screenshots of both.
