CodeCub vs Code Quest Pro

CodeCub teaches you Python in tiny, deterministic lessons — then makes sure you actually remember it. WHAT IT DOES • Bite-size Python: 54 hand-written lessons across 10 tracks, each just a few minutes long. • Real, instant checks: predict the output, fill the blank, order the lines, or pick the answer — graded on-device, deterministically. No AI guessing, no running your code. • Spaced repetition that works: a true SM-2 scheduler brings each concept back exactly when you're about to forget it, so it sticks for good. • A real path: lessons unlock in order as you master their prerequisites, from print() all the way to classes and regex. • Streaks, XP and a daily review reminder to keep the habit going. FREE BY DESIGN The full foundation course — Python Basics, Strings and Control Flow (21 lessons) — is free forever. No forced trial, no account, no card required. Your progress lives on your device. CODECUB PRO CodeCub Pro is an optional auto-renewing subscription that unlocks the 6 advanced tracks — Data, Functions, Comprehensions, Errors, Files & Modules, Classes and Regex (33 more lessons), all with the same spaced-repetition review. Subscription: auto-renews unless canceled ≥24h before the period ends; payment charged to your Apple ID at confirmation; manage/cancel in App Store settings.

Code Quest turns your phone or tablet into a real coding classroom. Write actual C, C++ and Python (not pseudocode) and run it right on your device, with a full offline compiler and interpreter built in. WHY CODE QUEST • Real code, real output: C/C++ compiles with clang and Python runs on Pyodide. No simulated runs. • Fully offline: every lesson and both language engines are built into the app. No internet needed to learn. • No account: no sign-up, no login, and nothing is uploaded anywhere. Your progress stays on your device. • Bite-sized lessons: each lesson explains one idea, then lets you write and run code right away. • Boss battles: every module ends with a quiz built from its own lessons, shuffled, to check you really understand it. • XP, levels and streaks: earn XP for lessons and quizzes, keep a daily streak and level up as you go. • Search every lesson: type a topic like "pointers" or "for loop" and jump straight to it. WHAT YOU'LL LEARN • C: from your first program to pointers, structs and file handling • C++: classes, inheritance, templates and modern C++17 features • Python: syntax, data structures and real scripts you can run instantly • CS Foundations: core data structures and algorithms, with runnable Python examples BUILT FOR LEARNING ON THE GO The code editor has syntax highlighting, a real terminal, and graphics and colour output for C/C++, so you can see exactly what your program does. Device care settings limit run time and memory, so a runaway program never freezes your phone. OPTIONAL ONLINE EXTRAS Everything above works in airplane mode. If you turn on Settings > Online extras, Python's numpy, pandas, matplotlib and requests packages are downloaded the first time a program uses them (several MB each, only once). It's off by default. PRIVACY No accounts, no analytics, no ads, no tracking. The privacy policy, support contact and open-source licenses are in Settings > About. Whether you're new to programming or brushing up before a class or interview, Code Quest lets you learn by writing and running real code, anywhere, with nothing to sign up for.
