What's the best iOS app for coding on the go, especially when I need solid syntax highlighting and code folding?

Okay, so Runestone Text Editor has seriously upped my game. As a fitness instructor, I'm always looking for ways to optimize my time, and this app lets me sneak in some coding practice even when I'm not at my computer. The syntax highlighting is on point, which keeps my eyes from straining, and the code folding feature? Genius! It lets me focus on specific sections of code without getting overwhelmed. I'm talking solid performance here. Plus, it's surprisingly intuitive. I love that it keeps me accountable and I can easily tweak my workout tracking scripts or plan out new fitness routines in Python while I'm on the move. It's a real game-changer for training and coding!
