We do have a fully functional demo of EasyWorship that does not expire.  It will, however, have a watermark on the live output if you try to use it in a live service.  You can download the demo HERE.

If you would like to try EasyWorship without the watermark in a live service, you can purchase a one month subscription to remove the watermark and can then cancel after one month if it is not the right presentation software for you.
