Cozytek Code vs Folio

Cozytek Code helps you prepare for coding interviews by learning and practicing reusable data structure and algorithm patterns. Learn core DSA topics through visual lessons and guided practice, including arrays, strings, hash maps, two pointers, sliding window, binary search, trees, graphs, DFS, BFS, backtracking, heaps, greedy strategies, dynamic programming, sorting, and Big-O analysis. Each topic helps you build the reasoning behind a strong interview response: • See how the pattern works • Recognize the signals that point to it • Understand the strategy and key invariants • Build a clear solution outline • Study code examples, edge cases, and Big-O tradeoffs • Practice turning the approach into a structured solution • Track mistakes, accuracy, progress, and mastery The goal is not to memorize one answer. It is to understand the pattern well enough to recognize it across different problems, explain your approach clearly, and structure a solution with confidence. Practice with a growing library of interview-style problems, solution guides, and pattern-focused mastery checks. Add custom interview questions you want to practice, track your own practice metrics, and save problems to revisit through a spaced-repetition review cycle. Full access is available with a premium subscription. Premium unlocks the complete DSA curriculum, practice library, solution guides, mastery checks, custom practice tools, and detailed progress tracking. Your progress, attempts, time, mistakes, accuracy, streaks, and mastery state stay on your device and can sync privately through iCloud when available.

You tour five colleges in three days and by the end they blur together. Which one had the dining hall you liked? Where did the tour guide say the thing that stuck? Folio is a journal for college visits. Rate a campus while you're standing on it, write down what you actually noticed, and keep it somewhere you can compare later. TWELVE THINGS WORTH REMEMBERING Each visit walks through twelve prompts, in the order a real tour unfolds — First Impression, The Tour, Academics, Housing & Campus Life, Dining, Social Scene, Athletics & Spirit, Location & Surroundings, Cost & Value, Career & Future, The Feeling, and Final Verdict. Rate each one out of five, write as much or as little as you want, and add photos from the day. Every card is optional. Skip what doesn't apply — a category you didn't rate never drags your score down. SEE YOUR OWN PATTERNS Rate a few schools and Folio starts showing you things you never said out loud. A radar chart compares up to three colleges side by side across five dimensions. "What You Look For" averages your ratings across every visit to show which parts of a campus you actually care about — and which one you're toughest on. PLAN WHAT'S NEXT Save upcoming visits to a calendar and get a reminder the evening before and the morning of, so you're not scrambling. Keep a wishlist of schools you're curious about but haven't seen yet. TAKE IT WITH YOU Export everything as a document you can print, email, or bring to a meeting with your counselor or your parents. Your notes are more useful in the room where the decision gets made. SEARCH ANY U.S. COLLEGE Search runs against the U.S. Department of Education's College Scorecard, so you get real enrollment numbers, acceptance rates, tuition, and campus setting for schools across the country. YOUR NOTES STAY YOURS Your reviews, ratings, and written notes are stored on your device, not on a server. No ads. No tracking. No analytics of any kind. Because your journals live on your phone, use Export My Data now and then to keep a copy somewhere safe. FOLIO PREMIUM Free includes 3 colleges, 3 planned visits, 10 wishlist saves, and 10 photos per college. Premium removes those limits — unlimited colleges, planned visits, and wishlist saves, 25 photos per college, and PDF export. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
