Using iPad as a midi launchpad to execute km macros

Hi. My apologies if this is a repost. I am looking for ways to use my iPad to execute km macros on my Mac. Is this possible? I am not looking to do anything music related, just a way to having km macros presets on my iPad.

I’ve looked into several apps such as touch osc and lemur but I am not sure how this would work.

Such as this one here ?

I don't think it's been updated for a while, but it still works fine on my iPad mini 4 running iOS 11.
