XQ Arena is now on iOS, too.Find it on the App Store & Google Play
Welcome to H&Row Studio!
What began as a hobby to understand how things work has grown into a collection of practical apps and playful games. I hope you enjoy them as much as I do.
And a little flying game: Skybound
Xiangqi is a classic worth passing on. I made XQ Arena to help more people discover it, even if they’ve never seen the board or read a Chinese character.
The idea is simple: keep the game’s depth, make the first few moves feel welcoming, and give friends a good reason to play together.
Available on iOS and Android.
Free to play. No ads. No in-app purchases.

Not everything I build has to be practical! Turn your phone sideways, dodge birds and storms, grab coins, and land on runways to refuel. Unlock 40 aircraft and characters, from jets and spaceships to dragons and a flying pig. Most of them are armed, with anything from homing missiles and lasers to dragon breath and bananas, and a boss waits every kilometre. No ads, no in-app purchases, no account, and it plays fully offline.
Available only on Android.

I’m not a tech startup. Just a guy with a day job who likes building little apps to solve my own everyday problems.
Little utilities designed to do their job without making a fuss.
No startup goals or roadmaps. Just a hobby I enjoy in my spare time.
I just make things I want to use. If they happen to help you out too, that's awesome.
