Codewise vs Mimo vs SoloLearn
Most coding apps are free to download and then ask for a monthly subscription to keep learning. Codewise is built differently: pay once, own it, and learn at whatever pace suits you.

No. Codewise is a one-time purchase on the App Store. There is no subscription, no in-app purchases, and no ads. Buy it once and it works on iPhone, iPad, and Mac through universal purchase.
Does Codewise work offline?
Yes. Every language interpreter is built into the app, so challenges, code execution, and documentation all work with no internet connection. Nothing is sent to a server.
Which programming languages does Codewise teach?
Swift, Python, JavaScript, Java, Kotlin, and C#, plus an Intro to Programming module for complete beginners and Object-Oriented and Functional Programming modules for C#. Version 1.2 adds a PostgreSQL SQL module. Each language has around 30 challenges across Easy, Medium, and Hard.
Does Codewise run on Mac?
Yes. Codewise is a native Mac app as well as an iPhone and iPad app, and it is a universal purchase, so one purchase covers all three. Your challenge progress is tracked on each device.
Is Codewise for complete beginners?
Yes. The Intro to Programming module assumes no prior experience, and every language track starts with Easy challenges on variables and printing before moving to conditionals, loops, functions, and collections. Each challenge includes a hint, starter code, and built-in documentation.
