Epheos Keyboard is a highly customizable, power-user-oriented input method designed for productivity, coding, and advanced text editing on Android built entirely with Jetpack Compose.
Desktop Controls
Full PC modifier keys (Ctrl, Alt, Shift, Arrow, Fn)
Macro Engine
One-tap insertion of custom snippets & templates
Total Privacy
100% offline with zero internet permissions
Key Pain Point: Mobile text editing and terminal management suffer from the lack of persistent modifier keys (Ctrl, Alt, Esc, Arrows).
We designed and built Epheos Keyboard using Jetpack Compose to deliver a fluid, high-performance typing experience. It features full desktop modifier key support (Ctrl, Alt, Shift, Fn, Arrow keys), a custom snippet macro engine, customizable screen positioning (top or bottom), a quick-toggle symbol mode, custom themes (including Epheos Blue), tactile haptics, and zero network permission requirements to guarantee absolute privacy.
Jetpack Compose enabled rapid UI iteration and fluid animations for dynamic layout transitions and custom key popup rendering.
Implementing desktop modifier states required careful handling of Android InputConnection events to synthesize key strokes accurately across third-party apps.
Offline-first architectural constraint ensured user data, keystrokes, and custom snippets never leave the local device storage.
Epheos Keyboard transforms mobile typing into a desktop-class editing environment for power users, developers, and writers on Android. Built from the ground up with Jetpack Compose, it bridges the gap between smartphone inputs and desktop hardware capabilities.
Our research revealed critical insights that informed our strategy and implementation.
