<h2>Built solo by Roman Tsisyk.</h2>
<p>Every app in this family is designed, built and maintained by one person: <strong>Roman Tsisyk โ a software engineer and Android developer</strong>. He rebuilt a library of self-development titles into a single, modern Kotlin & Jetpack Compose codebase โ so hundreds of thousands of existing readers kept their progress while the apps became faster, cleaner and consistent.</p>
<p>The reading engine renders every chapter natively in Compose โ no WebView, no tracking โ 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.</p>
<p>Beyond the RomanT apps, Roman writes and builds at his personal site โ the best place to explore his other projects and get in touch.</p>
