Four offline study apps, one per NVIDIA certification exam
Each app holds the practice questions for a single exam, with a written
explanation for every answer option. Buy it once, open it on a plane, and never see an
account screen, an ad or a loading spinner.

Why four apps and not one
Each exam has its own question bank, its own domain list and its own way of asking.
Mixing four of them into one download would mean paying for three exams you are not
sitting, and searching the store for your exam would not find it. So each app carries
one bank, one icon and one colour, and you buy only the one you need.
The same promises in all four
- One-time purchase. No in-app purchases, no subscription, no locked sets
- Everything is unlocked from the first launch — there is nothing to earn or wait for
- Completely offline. The apps make no network requests at all, in any screen
- No account, no sign-in, no email address, no push notifications
- No ads, no analytics, no tracking, no advertising identifier
- An explanation for every answer option, not only for the correct one
- Exam mode with a timer, and practice mode that answers as you go
- Automatic lists of the questions you missed and the ones you bookmarked
- A score breakdown by domain after every set, so the weak area is obvious
- Light and dark themes, or follow the system
- Your progress is written to the device only, and it is deleted with the app
About the questions
The questions and the explanations in all four apps are written with AI, then
organised against the domains each certification publishes. They are original practice
material. They are not real exam questions, and no exam question is reproduced in them.
AI-written material can be wrong: if something looks off, write
to us and the correction ships in the next update for everybody.
Who makes these
Bridge AI is a one-person studio in Tokyo. The person behind it has passed all four
of these exams, plus NCP-GENL, and holds more than thirty IT certifications. The apps
are the study material that was missing while sitting them — something to work
through on a commute with no signal.
Where to buy. The four apps are not on the stores yet. When they are, the
download links will appear on this page and on each app's page.
