The Jekejeke Prolog runtime library is an interpreter only implementation of Prolog written in 100% Java. The runtime library provides a simple console interface and no debugger. The implementation of the language mainly follows the ISO Prolog core standard. The implementation also features an application programming interface.

The interpreter has been tested with earlier smartphones running Android 2 (Froyo) and with newer tablets running Android 4 (Ice Cream Sandwich). Bug reports and feature requests can be sent to . The screenshots 1-3 show the interactive interpreter in action.

The screenshots 4-6 show an example application that makes use of the embedded interpreter. The interpreter.apk cannot be directly embedded. One has to obtain from the web site at to be able to compile the application.

There is also the Jekejeke Prolog development environment for Android which features a debugger. For the moment it can only be downloaded from the web site. On the web site one finds also Swing versions of both the Jekejeke Prolog runtime library and the Jekejeke Prolog development enviroment.
