Introduction

You might be familiar with the scientific Palm OS application offered at: Bray Palm OS Page.
This Bray Mobile Applications page offers similar freeware applications which will run on a variety of computers.

These application are written in Ewe*, a variant of Java. There are Ewe runtime package available (for free) for the following computers:

PocketPC     HandHeldPC Pro     Sharp Zaurus SL-5500
PalmPC (WinCE)     Casio BE-300     Any computer running Java 1.x VM
Windows Desktop     Linux Desktop

One of the features of Ewe is that the very same application can run on both your desktop OS and your mobile OS.

To run these applications on your computer you must install a Ewe VM (Virtual Machine) on your computer. Ewe is very compact and efficient. It uses only about 2 Mbytes of memory. Check out Ewe at: http://www.ewesoft.com.

If you want to download one or more Ewe VM's for your computers read about it at Ewe Download and Installation Instructions the end of this page.
