CHM Viewer

CHM Viewer is a lightweight reader that lets you open and read CHM (Compiled HTML Help) files on Android with speed and simplicity. Built around a native C++ rendering engine and a Jetpack Compose interface, it makes large documentation and offline manuals load quickly and scroll smoothly on phones and tablets. If you often consult technical docs, programming help files, or archived manuals while away from a desktop, CHM Viewer provides a focused, modern reading experience with system-wide dark mode and a clean Material 3 layout that keeps navigation distraction-free.
