What's a good iOS game for boosting reaction time between clients, something quick and kinda zen?

Okay, so Stickman Hook is a game I've been using to sharpen my reflexes. As a fitness instructor, that split-second decision-making is key, ya know? This game is perfect between sets, or while I'm waiting for my next client. It's all about timing your swings and releases to get that stickman to the finish line. It's not gonna replace my HIIT workouts, but it's a fun way to keep my mind sharp and my reactions quick. Plus, it's surprisingly zen. The simple graphics and physics are oddly calming, even when I'm failing a level for the tenth time. I've noticed a slight improvement in my overall coordination since I started playing, and anything that helps me coach better is a win in my book. It's a game-changer for training my brain!
