Two questions a day, written to be learned rather than looked up. 600+ across 30+ categories, from your first variable to Kubernetes, with a check at the end of each. Devprompt is for keeping your knowledge as a developer — not looking things up, which a model does better, but knowing them, which only you can. Every question is written to be learned. One line you can keep. A sentence you can say out loud in an interview. Plain terms when the jargon is in the way, then the depth and the code underneath. And at the end of each one, two questions to answer before you move on, because the difference between knowing a thing and having read it is whether you can produce the answer with the page closed. TWO A DAY Open the app and there are two readings waiting, from two different subjects, chosen for today. Read them, check yourself, close the app. One a day is the habit; two is a good day. A random button is there for a third. 600+ QUESTIONS, 30+ CATEGORIES Start here if none of it is familiar: what a program is, what a variable is, what a server is. Then JavaScript, TypeScript, Python, Ruby, Go and SQL. React and the browser. Node, databases and how to tune them, Kafka, system design. Behavioral rounds and the career questions around them. AWS, Google Cloud and Azure. Containers, Terraform, CI/CD, GitHub Actions, SRE and security. AI and how to build with it. Algorithms, testing, Git. Everything a 2026 interview loop actually asks, and everything a working developer is expected to know. IN THE LANGUAGE YOU ARE LEARNING The foundational questions carry every sample in JavaScript, Python, TypeScript and Ruby. Pick once, and every example switches. WHAT IS CHANGING A Trends tab: what is rising, what is established, what is fading — and what to do about it. Every entry is dated, so you can see how recent the judgment is. BUILT FOR THE HABIT Search across everything. Browse by level, by category, by language, or by track. Track what you have done, keep a streak, mark what to review. A Companion mode that listens to an interview and shows the answer to what was just asked. OFFLINE, PRIVATE The whole library ships inside the app, and nothing works worse without a connection. No account. Your progress, your streak and your bookmarks stay on your phone. The app checks once a day whether a newer version exists and sends anonymous usage counts — which screens and questions are opened, never anything you type or say — tied to a random install token, not to you or your device. ONE PURCHASE Try the free questions in every category. One purchase unlocks the whole library forever, including every category added later. No subscription. New content every month.
