Leetstreak turns coding interview prep into a daily habit that actually sticks. Most developers study in bursts — cramming before interviews, burning out, then starting over. Leetstreak fixes this with a streak-based system that keeps you practicing consistently, so when the offer comes, you're ready. PERSONALIZED DAILY PROBLEMS Every day you get three problems — easy, medium, and hard — chosen by your dream company, focus topics, and weak spots. Not random. Not generic. Tailored to your actual goals. INTERVIEW MODE Practice under real conditions with a live countdown timer and hints delivered at the right moments. Log your outcome, track your time, and build the muscle memory that matters on interview day. SMART INSIGHTS See exactly where you stand with topic breakdowns, solve rate trends, and a 52-week activity heatmap. Know your weak spots before the interviewer finds them. STREAK SYSTEM Your flame stays alive when you practice daily. Miss a day and it fades. Complete a problem and it bounces back. Simple, visual, and surprisingly motivating. SOCIAL ACCOUNTABILITY Follow friends, give props on solved problems, and share insights in the comments. Public commitment increases follow-through — your streak is visible to your network. SPACED REPETITION BUILT IN Problems you struggle with return at the right intervals so you improve where it counts most. The algorithm never stops learning from your attempts. Leetstreak is for software engineers who are serious about landing the offer — whether you're actively interviewing or staying sharp for when the right opportunity comes. A subscription is required to access all features. Weekly and yearly plans available. Terms of Use: https://www.leetstreak.app/terms Privacy Policy: https://www.leetstreak.app/privacy
