I recommend free and open source software for everyone. Everything on this list is curated to feature the best alternatives to common proprietary software (according to Linux Cafe):

I think the best two are Simple Keyboard and AnySoftKeyboard. Simple Keyboard is pleasant to use, but is missing a several advanced features.

Finally, try to get comfortable going to alternativeto.net when you get frustrated with software. Worst case scenario you get frustrated with different software for a bit and switch back. Of course it notes the price and license model for each alternative.
