Every app in this family is designed, built and maintained by one person: Roman Tsisyk — a software engineer and Android developer. He rebuilt a library of self-development titles into a single, modern Kotlin & Jetpack Compose codebase — so hundreds of thousands of existing readers kept their progress while the apps became faster, cleaner and consistent.
The reading engine renders every chapter natively in Compose — no WebView, no tracking — with Light, Sepia and Dark themes, adjustable type, offline text-to-speech, knowledge-check quizzes, and full localization into 13 languages. The guiding rule is simple: genuinely useful content, offline-first, and no dark patterns.
Beyond the RomanT apps, Roman writes and builds at his personal site — the best place to explore his other projects and get in touch.
Pick any app, download once, and keep learning without a connection. New chapters, quizzes and languages, all included.
