Yes, It’s actually very fleshed out. For starters, the cross doesn’t have diagonals so you’re less likely to mess up your placement. And then you can actually move around and resize the buttons to your liking on the settings. Here’s a screenshot of how my controls look now:

Hey I actually gave it a try and I could compile it for android!

It even has a battery indicator lol, pretty awesome!

Tetr.io is an awesome way to play if you prefer playing on a physical keyboard. I do wish it had a mobile client

I’d say its customization and flexibility sets it apart, as having a gba rom makes it playable on virtually anything these days. I say “definitive way” because my playtime is usually done on my phone, and I haven’t found an alternative I liked better for my use case. TGA might appeal more to those who are specially sensitive to input lag, like speedrunners, while Apotris gets the basics right and lets you play on a long queue.
