Why Certisimo

Built around one exam — yours.

Practice like it's exam day

A training mode that explains answers as you go, and a timed exam mode whose clock keeps running even if you switch away — because the real one does too.

Works with no signal at all

The full question bank ships inside the app. Airplane, basement, exam-center hallway — nothing to download, nothing to wait for.

Know when you're ready

A readiness score plus your weak, hard, new and strong questions — so you drill what actually needs drilling.

Your studying is nobody's data

Progress, history, favourites and notes live on your device. Certisimo has no account and no sign-in — there is nothing to leak.

Is Certisimo free?
Yes — every edition is free to download on the App Store.
Which certifications are covered?
25 of them, one app per certification: 9 for Google Cloud, 8 for AWS, 8 for Microsoft Azure. The full list is right above — pick yours and everything in that app is about that exam.
Do I need an account or an internet connection?
Neither. There is no account and no sign-in, and the questions, answers and explanations ship inside the app, so it works entirely offline.
Where does my progress live?
On your device, and only there. Deleting the app deletes your progress. What the app does send — crash reports and usage statistics, not tied to your identity — is written out in full in the Privacy Policy.
Is Certisimo affiliated with Google, Amazon or Microsoft?
No. Certisimo is an independent study tool and is not affiliated with, endorsed by or sponsored by any certifying body. Certification names are trademarks of their respective owners.
