We develop apps and games for the Apple ecosystem – for iOS, iPadOS, and macOS. Our portfolio currently includes several macOS applications, featuring both established tools and new programs that are about to be released. In addition, we offer multiple games as well as long-maintained iOS and iPadOS utilities that have been continuously updated for over twelve years.
Some of our applications reached #1 in the Finance category in more than 22 countries.
Our products are published under three labels:
AtomiumGames for our games
OneTwoApps for our iOS and iPadOS utilities
BetterLocale for our macOS tools focused on Apple development
Our current focus is on professional developer tools for the Apple platform. We are building solutions for localization, App Store management, crash analysis, and structured documentation – with the goal of making development processes more efficient, transparent, and reliable.
On this website, you will find an overview of our apps, games, and ongoing projects.
Before introducing the products, I would like to share a free tool with you, developer to developer, that can noticeably speed up everyday development work. The Toolbox brings together many recurring tasks around Xcode, builds, tests, simulators, analysis, and maintenance in one central script, helping you save time, clicks, and unnecessary detours. If you work with iOS or macOS projects and want to handle common workflows faster and more consistently, you can download the tool for free on GitHub (https://github.com/drapatzc/toolbox.git).
