Write and run real Pascal programs on your iPhone.
With a Turbo Pascal theme that'll make you feel 16 again.
Because some of us peaked in the 90s — and that's okay._
Coming Soon to the App Store
Pascal Playground is a code editor and interpreter that runs real Pascal programs directly on your device. No server, no cloud, no Wi-Fi required.
Whether you're reliving your CS101 days or introducing someone to structured programming, Pascal Playground gets out of the way and lets you write code.
A proper code editor with syntax highlighting, auto-indentation, and a full keyboard row for Pascal-specific characters.
Hit Run and see the output immediately. Variables, loops, functions, arrays — all interpreted on-device in real time.
Save and open .pas files. Keep your programs organized and pick up right where you left off.
Switch to the Retro theme for that authentic Borland blue experience — cyan gutters, yellow commands, monospaced everything. Or keep it Modern and let it blend in with the rest of your apps.
Borland blue · Cyan gutters · Yellow commands
Follows system appearance · Light & dark
On first launch, Pascal Playground asks you to choose your style. Both themes include a live code preview so you know exactly what you're getting into.
(You can change your mind in Settings any time. We won't judge.)
Pascal Basics is built right into the app — no browser tab needed. Browse data types, control flow, procedures, functions, and more with real code examples.
Great for beginners learning structured programming, and equally handy for the experienced dev who just can't remember whether it's div or mod for integer division.
Tap Run. See output instantly. Integer and real arithmetic, strings, booleans, arrays, for/while/repeat loops, procedures, functions — the classic Pascal you remember, running on your phone.
Pascal Playground is coming to the App Store. Stay tuned.
