Tested in real use
Every app is used daily before each release. Family testing with real users, not just ideal cases.

Personal project
García³ Apps was born from the vision of a frontend developer with 7+ years of experience: everyday tools can be better. Each app is designed, developed, and tested in real daily use before publishing. No huge teams, no committees. Just one person solving real problems with professional-quality software.
One app, one job
One main function per app. Minimalist but polished UI. Works out-of-the-box.
Zero warnings, 60 FPS
Zero warnings in static analysis. Constant 60 FPS. Under 2 seconds response time.
