Emu48 is an Android-based calculator application that has been ported from the Windows version, written in C. The Android version of Emu48 has been developed by Regis Cosnier and distributed under the GPL license. The application uses the Android NDK and has a thin win32 emulation layer above Linux/NDK, which allows easy updates from the original Emu48 source code. Emu48 for Android can open and save the exact same state files (state.e48/e49) as the original Windows application.

Emu48 for Android has some KML files with their faceplates embedded in the application, but it is still possible to open a KML file and its dependencies by selecting a folder. The application does not request any permission because it opens the files or the KML folders using the content:// scheme. Additionally, the application does not contain any ads or in-app purchases. The not-yet-working features include the disassembler and debugger. Overall, Emu48 for Android is a reliable application that provides users with a great experience.
