About Developer Tools on the Japan App Store
Developer Tools is a niche but high-intent category covering code editors, SSH and terminal clients, Git clients, API testers, regex and JSON utilities, and on-device script runners. Because most software development happens on desktop, the iOS chart leans toward portable utilities, learning resources, and companion clients for cloud platforms (AWS, GitHub, etc.). Free rankings often reflect viral utilities and recent launches; paid rankings are stable and surface premium editors and reference apps. Rankings update daily.
Examples: Working Copy, Termius, Pythonista, Prompt, a-Shell
