EnCalc (Calc4all) is a portable windows calculator with practical built in features! This project started out because there was no other simple portable calculator out there with all the features that I wanted built in. EnCalc has a simple, easy-to-use interface with so many useful features, you'll find that it will quickly become your favorite calculator!

Simple installation program, or just copy the folder and run the program direct. Uninstall by simply deleting the folder and whatever shortcuts you've created. No system files, no .dll's, no add/spyware, and no registry changes. Leaves nothing behind to bog down your computer.

All of our downloads start out as the free version. There are no time/usage restrictions on this version of our software. If you like it, please help spread the word by passing the free (unregistered) version on to your friends/co-workers. Our free versions limit extreme features of the program. If you don't need these features - then no need to buy the registered version.
