It's chorded, (based on the https://ardux.io/ layout), but I don't think chorded is really that hard to learn if you're actually willing to give it a week or two (which you have in any situation where you need a one hander).
The key (ha) I've found is that you want the keys to be as easy to press as possible while providing feedback. The Twiddler, https://twiddler.tekgear.com/ , is great for this as it uses light tact switches, but it has reliability issues.
This is a great project. Of all my one-handed experience, I never got to try a FrogPad because of the expense. Having a software implementation of the FrogPad is awesome.
