Every attempt, recorded
Log the outcome, the language, the time it took, and what went wrong. Come back in three weeks and the context is still there.
Deliberate practice
Leetly keeps the record of how you actually solved a problem: every attempt, every wrong turn, and when to come back to it.
Free, and your data stays yours.
Six things a problem list cannot tell you, and the reason a solved count is a poor measure of readiness.
Log the outcome, the language, the time it took, and what went wrong. Come back in three weeks and the context is still there.
Solved problems enter a spaced-repetition schedule. Leetly decides what is worth revisiting today so you do not have to guess.
Daily streaks, solve rates by difficulty, and an activity heatmap. Enough to see whether the last month actually moved.
Tag why an attempt failed: off-by-one, wrong pattern, missed edge case. The pattern in your errors becomes visible.
Group problems by topic, by company, or by whatever you are drilling this week. Track how much of each list is genuinely done.
Markdown notes with syntax highlighting, attached to the problem they belong to instead of scattered across other apps.
Log one attempt and the record builds itself from there.
