Depends on device you are using but on most mobile ones there is a setting on phone or tablet so you can swap keyboards as needed. You will have to research online for your particular device. If on a laptop or pc, I believe they have free virtual keyboards for most software setups.
There are many language apps but would imagine most at some point would require using keyboard specific to that language.
The only problem I have had on mobile is that sometimes I start typing and realize I am on another language keyboard and have to change it back to English but easy to do.
