Altab AI vs Hourly DSA

You know the theory. You've never built anything. Arrays, data types, Big O. Then a blank file and the two questions school never answered: where do I even start, and how do I get the software engineering job? The job wants practical experience, and the degree never gave you any. Altab is the roadmap from there to senior, and your own project is the first thing on the road. You pick something real to build on day one. Each stage tells you what to build next, short lessons teach exactly what that stage needs, and you send in what you built and get written feedback on it before the next stage opens. THE ROADMAP, IN ORDER · Your project: the thing you are building, from day one · Getting oriented: files, folders, and the terminal · Things talking to things: how the internet works, front end, back end, APIs, databases · Your tools: the editor, version control, and the rest of the bench · How code works, making it run, when it breaks, and the bug factories · Shipping it: hosting, deploys, containers, remote machines · Working with an agent, then taking real products apart Nothing is skippable and everyone starts at the beginning, because the thing that stopped you was never the hard part at the end. HOW A LESSON GOES 1. One idea, in plain words, with a picture. 2. A handful of short questions. The tap is the answer. 3. The explanation, every time: why the right answer wins, and why the one you wanted tempted you. THE HABIT · Five minutes a day, first question in minute one · Wrong answers never cost you. The explanation shows up either way · Spaced review brings a missed idea back before you forget it · Streaks with no hearts and no lockouts. A rest day is never a zero · Weekly leagues, XP, and a record card WHO IT IS FOR CS students and new grads who can pass the class and still cannot build anything. You know the theory, you have watched the tutorials, you have taken the classes, and a blank file still stops you. You build your own project from day one and the roadmap teaches what each stage needs. FREE AND PREMIUM Lessons 1 and 2 of every course are free. No card required. Premium unlocks every lesson after the second in every course, your own project with written feedback at every stage, spaced review, and new courses as the tools change.

Build your coding interview instincts, one short session at a time. Hourly DSA helps you learn data structures and algorithms through bite-sized lessons and quick practice. Recognize common patterns, think through code, and understand why an answer works. LEARN A LITTLE, EVERY DAY - Explore short lessons with guided examples and practice questions. Track completed lessons and pick up where you left off. MAKE EVERY BREAK COUNT - Take on a five-question daily set or practice a specific topic. Short prompts and tap-to-answer choices fit naturally between classes, meetings, and whatever comes next. SPOT THE PATTERN - Learn when to reach for a hash map, two pointers, sliding window, binary search, and more. Build confidence choosing an approach and understanding why it fits. THINK THROUGH THE CODE - Predict the output of short snippets, reason about time and space complexity, and spot common misconceptions. Get immediate feedback and a clear explanation after every answer. BUILD ON WHAT YOU LEARN - Review missed questions, practice weaker topics, and track your progress. Earn badges and keep your streak going as you build a daily habit. KEEP PRACTICE CLOSE - Add Home Screen and Lock Screen widgets to keep questions, interview patterns, and your streak in sight. TOPICS INCLUDE - Arrays and hash maps, two pointers, sliding window, stacks, binary search, linked lists, trees, heaps, backtracking, graphs, and dynamic programming. Whether you're preparing for a software engineering interview, studying computer science, or refreshing the fundamentals, make room for a little DSA every day. --- Hourly DSA requires a subscription for practice and widgets. Choose annual with a 7-day free trial for eligible subscribers, or monthly without a trial. Both plans include every topic, unlimited practice, missed-question review, weak-topic drills, progress, and widgets.
