Good Utility Developer (GUD) is an independent iOS app studio that creates simple, well-crafted apps — from casual games to everyday utility tools that make life a little easier.

GUD believes the best apps don't need to be complicated. Whether it's a fun puzzle game or a handy utility, every app is built with a clear purpose: easy to use, smooth to run, and enjoyable for everyone.

Every release is designed with care — clean interfaces, satisfying interactions, and thoughtful features that users actually need.
