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.
