Everything you need to land the job
Lock The Code combines the tools that actually move the needle so you practice smarter, not longer.
Spaced-Repetition Reviews
Problems resurface right before you'd forget them, powered by the SM-2 algorithm. Build lasting memory instead of cramming the night before.
AI Interview Simulator
Face a realistic mock interviewer that asks follow-ups, pushes on your reasoning, and grades your performance. No peer session needed.
AI Tutor
Stuck on a problem? The tutor gives Socratic hints that guide your thinking without handing you the answer, the way real learning works.
Problem Tracker
Log every problem you solve with difficulty, topics, patterns, and personal notes. Your entire prep history in one place, always searchable.
Algorithm Flashcards
Lock in the patterns that keep showing up: sliding window, two pointers, dynamic programming and more, with spaced-repetition flashcards.
Daily Review Queue
Wake up to a personalised queue of exactly what's due today. No guessing, no overwhelm; just the right problems at the right time.
Never miss a review day
Lock The Code emails you when problems are due, so you stay consistent without having to remember anything yourself.
No spam. One email a day, only when you have problems due.
