BetterDummy alternatives

I use Luna Display every single day as an interface for a headless Mac server I have in my setup. Works flawlessly with recent updates. If I had one major complaint/wish it would be for Luna to utilize the built in keyboard function in IOS. Having to peck out characters on the remote Mac using Mac OS keyboard viewer is frustrating to say the least and really takes away from the experience. Ive read that the only workaround is to purchase their Astropad software which seems like overkill to obtain this functionality and sort of smells of a money grab?

What a contrast! Duet Display wreaked havoc in my house of apple. But it took 2 years to find out it was upsetting Hand Off, the universal clipboard, AirDrop etc!! Pretty crucial features when you have 2 separate machines. Even after giving up on it after a month..... The Luna Display was up and running in minutes. I can even still listen to the music on my secondary machine with the keyboard still controlling the tunes while working on the display !! how do they do that!!?? Support's great as well, they even sent me a freeby when I received the wrong one. Maybe I'm not meant to say that..... thanks Astropad. Having my 2 27's working together is finally happening! and really well too
