About

One person, full stack, every pixel.

JB Apps is the indie studio of Jose Blaya. Every app here is designed, built, and maintained end-to-end with a simple philosophy: follow native platform design, keep things focused, and sweat the small details. If something breaks or you have an idea, you talk directly to the person who wrote the code.
