Remember what you solved.
Re-practice before you forget.

Code Tracker keeps every problem you have worked on in a category tree, records how familiar each attempt felt, and tells you exactly which ones are due for another round.

Category tree

Main and sub categories you fully control: rename, reorder, drag problems between them.

Familiarity, not just done

Every attempt is logged with a 0–3 familiarity level, so the history shows how it really went.

Due by your own intervals

Set how many days each level earns before a re-practice. Overdue problems are impossible to miss.

Due, Recent, Stats

Plan today's session from the Due list, review what you did recently, watch weekly momentum.
