Python Coding Editor is a fully offline Python IDE for iPhone and iPad that puts a real Python interpreter in your pocket — no network, no accounts, no setup. Write, run, debug, and learn Python anywhere. Three full CPython runtimes are bundled into the app and you choose which version each project uses, with per-project isolation. A modern editor with syntax highlighting, multi-file tabs, a project explorer, and a distraction-free focus mode makes it easy to write real programs, while the in-app Jupyter-style notebook lets you mix code and markdown cells, run them one at a time, and see rendered output inline.

Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 16 screenshots above are Python Coding Editor's answers to those questions — they're public, they're real, and they made it through Apple's review.

Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
