Algo Mind turns abstract algorithms into something you can see. Every lesson pairs a step-by-step animated visualization with synced, highlighted code — you watch pointers move, trees grow, and tables fill in until the idea actually clicks. Stop memorizing solutions; learn the patterns behind them.

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. Premium is a subscription: $9.99 per month, or $69.99 per year. Payment is charged to your App Store account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel any time in your store account settings. A Restore Purchases button is on the paywall and in settings. Terms of Service: https://altab.ai/terms Privacy Policy: https://altab.ai/privacy Support: support@altab.ai
