I built an app, and it went live on the App Store today. It is called HOW TO AI — CERT, and it does one thing: it gets you ready to pass an AI certification in the gaps of your day.
4,675 original practice questions across 15 AI and cloud certifications. Plain-English explanations on every answer. Timed mock exams, weak-area drills, and an AI tutor for the moments when an explanation is not enough. Free to download, with free sample questions for every exam.

What’s inside
- 4,675 original practice questions, each one weighted to the official exam blueprint, so you practice what the exam actually tests.
- Plain-English explanations on every answer, right or wrong. The goal is that you understand the concept instead of memorizing a letter.
- Quick 10s, full timed mock exams, and weak-area drills that use spaced repetition to resurface what you miss until it sticks.
- A readiness score that tells you when you are actually prepared, so you book the exam with confidence instead of hope.
- An AI tutor, powered by Claude, for the follow-up questions an explanation alone does not answer.
- Question of the Day and streaks, because five focused minutes daily beats a panicked Saturday.
- Flashcards, cheat sheets, and a glossary for every exam. Works offline. iPhone and iPad, iOS 17 and up.

Not sure which one to sit? I ranked all 15 in The Best AI Certifications in 2026, including which ones hiring managers actually recognize.
What it costs
Downloading is free, and every exam has a free sample question set with no account hoops. If it clicks for you, Pro unlocks all 4,675 questions, all mock exams, the AI tutor, and every future certification I add, for $11.99 a month or $39.99 a year.
The honest note: all questions are original, written from the published exam objectives. No brain dumps, nothing copied from real exams, and no certification body endorses this app. It is independent, like everything else I make.
Studying on Android or a desktop
The app is iPhone and iPad only for now. If you are on Android, or you would rather study at a full-size screen, the practice dashboard at howtoai.com/ai-exam-prep runs in any browser today.
Questions people are already asking
Are these real exam questions?
No. Every question is original, written from each vendor’s published exam objectives. Brain dumps put your certification at risk and they teach you nothing, so the app does not use them.
Do I need an account to try it?
No. Download the app, pick your exam, and the free sample set opens right away.
Does it work offline?
Yes. Questions, explanations, flashcards, and cheat sheets all work without a connection. The AI tutor is the one feature that needs one.
Is it affiliated with AWS, Microsoft, NVIDIA, or any other vendor?
No. The app is independent, no certification body endorses it, and all trademarks belong to their owners.
How much should I study before booking the exam?
That is what the readiness score is for. It weights your accuracy by exam domain against the official blueprint, so a high score means you are covered across the whole exam rather than strong in one area. For a worked example of the pace, see the 2-week AI-901 study plan.
