A complete Python development environment that runs entirely on your device. Pyroid bundles a real CPython interpreter inside the app, so your code runs offline — on a plane, on the subway, anywhere. No account, no server, no setup. Just open a file and hit RUN. WHAT YOU CAN DO • Run Python offline Your scripts run in an embedded interpreter on your iPhone or iPad, with no internet connection. • 190+ libraries, preinstalled NumPy, pandas, Matplotlib, Seaborn, SciPy, scikit-learn, SymPy, Plotly, Bokeh, Pillow, Requests, Flask, Django, Kivy, Pygame and many more are ready to import from the first launch. • Package manager Browse what is installed with versions, authors and project links, then search PyPI to install more pure-Python packages — or uninstall what you no longer need. • Jupyter notebooks Open, edit and run .ipynb files in a real cell-based editor. Mix code and Markdown cells, run them one at a time, and see output, tracebacks and inline images right where you expect them. • Multi-tab editor Work across several files at once and switch instantly with a smooth tab bar. • Smart code assistance Syntax highlighting, suggestions drawn from your real Python environment as you type, real-time syntax checking, code folding, and Find & Replace inside the current file. • Step-by-step debugger Set a breakpoint on any line, then step over, into or out of your code — inspecting local and global variables, the call stack and watch expressions at every stop. • 100 coding challenges A built-in Practice screen with 100 Python problems, from your first loop to graph algorithms. Write the function, try it on the sample cases, then submit and get graded on hidden test cases — with hints, XP and a daily streak. • Rich, visual output A console for stdout and stderr, and a Preview tab that renders Matplotlib charts, opens interactive Plotly/Bokeh charts in a built-in viewer, and gives Markdown files a live preview. • A real workspace Create projects, files and folders; import from the Files app; clone a public GitHub repository; reopen recent work in a tap; and restore anything you deleted from Trash. • Learn as you go Every install starts with a built-in library: a 10-chapter Python course, from variables to loops, and a Data Science track covering NumPy, pandas, Matplotlib and Seaborn — all as editable, runnable files. • Made for how you work Dark and Blue editor themes, an adjustable code font, and a full interface in 12 languages, from English and Hindi to Vietnamese and Chinese. PERFECT FOR • Python learners and students • Developers who code on the go • Data analysis, plotting and quick prototyping • Interview practice away from a laptop FREE VS PYTHON PRO No ads anywhere in the app, free or Pro. Free includes the whole editor — multi-tab, debugger, notebooks, package manager, charts and previews — plus 5 code runs (a one-time allowance, not per day), 45 practice problems, 5 practice submissions a day and the first hint of every problem. Python Pro adds: • Unlimited code runs • All 100 practice problems and unlimited submissions • Every hint, plus the input and expected output of hidden test cases Plans: Weekly and Yearly auto-renewable subscriptions (both with a 3-day free trial), or a one-time Lifetime purchase with no renewals. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period; manage or cancel anytime in your Apple ID settings. Any unused portion of a free trial is forfeited when a subscription is purchased. Your code stays yours: files live in the app's own workspace on device, and only the code you write is executed.

Feed your brain. Level up. Learn to write real JavaScript by solving one puzzle at a time, right on your phone. JavaScript Challenge is a single path of original coding problems, from your first function to graphs, dynamic programming and beyond.
