How every course works

Taught like a good book with exercises, so you understand the subject instead of collecting bookmarks.

  1. Read a short lesson

    Each lesson is one sitting, split into small topics with examples, code and diagrams. Listen with read-aloud, and pick up exactly where you stopped.

  2. Practise with a quiz

    A few questions right after the lesson. Every answer comes with an explanation, and a wrong answer points you back to the topic to review.

  3. Pass the chapter test

    A timed test drawn from the whole chapter. Pass it to complete the chapter. The next chapter opens as you finish the lessons before it.

  4. Earn your certificate

    Finish every chapter and the final exam unlocks. Pass it to get a certificate with a serial number anyone can check.

What is TechStack Atlas?

TechStack Atlas makes course apps for tech skills. Each app teaches one course from start to finish, like a good book with exercises: short lessons, a quiz after each lesson, a test after each chapter and a final exam with a certificate.

How long does a course take?

A course is built for 10 to 20 minutes a day. Most learners finish in one to two months. Each lesson fits one sitting of about 10 to 15 minutes, and the app remembers exactly where you stopped.

Is it free?

Every TechStack Atlas app is free to start: the first chapters, their quizzes and tests, streaks and leaderboards. Premium unlocks every chapter, the final exam and certificate, offline access and no ads, as a monthly, yearly (7-day free trial) or lifetime plan. Prices are shown in the app store and vary by country.

How do quizzes, tests and the final exam work?

Lesson quizzes are short practice rounds you can repeat. Every chapter ends with a timed chapter test drawn from that chapter’s questions. When every chapter is complete, the final exam unlocks; pass it to earn your certificate.

Do I get a certificate?

Yes. Pass the final exam (a Premium feature) and the app issues a certificate with a unique serial number, so anyone you share it with can check it is real.

What keeps me going every day?

You earn XP for finished lessons and passed quizzes, keep a daily streak, set a daily goal and can see where you rank on weekly and all-time leaderboards. You can hide yourself from leaderboards at any time.

Do I need an account?

You sign in with Google or Apple so your progress, streak and certificate are saved and follow you to a new phone. You can delete your account at any time from the app.
