Free calculator software that resembles a graph calculator

[HueyLewis]

Are there any free software calculators that provides a similar user experience as a graph calculator like Texas inst. Ti-83?

I do not find the built in windows calculator to be easy and pleasant to use.

Thanks.

There's a TI-89 emulator app.
Look for Graph89 at Google Play.
Lots of YouTube vids about it.
You need to download its OS at TI.
Its name is TI89Titanium_OS.89u
