NumTest vs CodeCub

The primary objective of this application is to provide researchers with a mechanism for testing and comparing the performance of their numerical solvers. This application includes algorithms capable of benchmarking values on a diverse range of scientific numerical problems. It is important to note that the results presented are for comparison purposes only and are not guaranteed to be correct. We will be adding more topics in the future. Please encourage us by sharing this app with your friends and colleagues. Your support is greatly appreciated! If you have any questions or feedback, please contact us at daniel.hadush@gmail.com.

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.
