CertBrain is now on Android

by Miles Corran · October 22, 2026

CertBrain is now on Google Play. Everything you've been studying here for the AWS Certified AI Practitioner exam (AIF-C01) now fits in your pocket, so a commute or a spare ten minutes can count toward your prep.

What you can do in the app

The app has the same five courses as the website, one for each domain in the exam guide. In it you get:

  • Short lessons, each followed by a quiz of original scenario questions, with an explanation for every answer.
  • Spaced-repetition reviews. Each question comes back right before you'd be likely to forget it, so your review time goes to what you're about to lose.
  • Your progress through each course, a pointer to what to study next, and a daily streak.

Your progress follows you

Sign in with the same Google account in the app and on the website, and you pick up exactly where you left off. Read a lesson on your laptop, do its review on your phone later. It's the same progress and the same review schedule either way.

Start with the free diagnostic

Not sure where you stand yet? The app's sign-in screen has a Try the free diagnostic button. You don't need an account.

It's a short quiz across all five exam domains. Your answers are scored on your phone, and the results show how you did in each domain, name your weakest one, and explain every question you missed. That tells you which course to open first.

Get it

Get CertBrain on Google Play, or take the diagnostic on the web first.
