We're on a mission to create beautiful, intuitive applications that make your everyday life better. Whether you're tracking your mood, organizing memories, learning new skills, or building software, Caitty provides tools that are thoughtfully designed, respectful of your privacy, and delightful to use.
Founded on the principle that privacy is a fundamental right, not a luxury, every app we build stores your data locally on your device. We don't track you, we don't sell your information, and we don't compromise on security. Your personal moments, creative work, and daily reflections belong to you alone.
From productive developer tools used by thousands of programmers daily, to personal wellness apps that help you understand yourself better, each product reflects our commitment to quality over quantity. We'd rather build one exceptional app than ten mediocre ones.
Every feature is designed with your needs in mind, not corporate metrics or advertising goals.
Local-first architecture means your data never leaves your deviceβno cloud sync, no tracking, no surveillance.
No internet? No problem. Our apps work seamlessly offline, giving you control wherever you are.
Your data stays on your device. We never collect or share personal information.
