GameGlass is software that turns another device like tablet or phone into a macro pad for your PC. It was originally made by Star Citizen players and it worked well last time I used it in SC. Ideal for games with a lot of controls (flight sims, etc.). Because they're doing a major update they've brought back a lifetime pass for a limited time. The program works through their servers so you run the risk that they'll shut down in the future.
"Control your games in a brand new way, with GameGlass Shards - immersive touchscreen interfaces on your phone and tablet.
Shards let you use intuitive touch controls that include dynamic interactions and animations. Switches, buttons, toggles, sliders and more allow you to see your controls laid out clearly. Beautiful designs for a wide variety of game genres make them feel immersive."

"This release is the time to make Lifetime available once more, as we celebrate
the next 5 years of our journey."
"We chose a price that meant you'd save money if you used GameGlass for 4 years or
more - using our new annual price ($76.43AUD) as a guide."
If you have no idea what this is, because their website makes such a poor job of actually explaining it, it's like a digital version of StreamDeck which can be customised with different buttons for specific games to be used by a tablet or similar device:
