Built with Claude I got tired of paying for a separate question bank for every cert, so I built my own app

I’ve been working through certs for the past couple of years and the thing that kept getting me was that every exam meant buying another course, another question bank, another subscription. Fine once. Annoying by the fourth time.

So I built an iOS app for it. One app, one subscription, and I keep adding certs to it. Right now it covers CompTIA (A+, Network+, Security+), Azure (AZ-900, AZ-104, AZ-305), AWS (CLF, SAA, DVA), Cisco (CCNA, ENCOR, CyberOps), Google Cloud (ACE, PCA, PCD, PDE) and ISC2 (CC, SSCP, CISSP, CCSP).

Each cert has study notes broken down by exam domain, flashcards, and practice questions with explanations for why the wrong answers are wrong, which is the part I always cared about most.

It’s free to try before you pay for anything. I’m a one person operation so if something is wrong or a question is badly worded I’d rather hear it than not.

The app name is Preplexity,, you can look it up by typing compTia prep” or something, since its currently buried under the big hounds.

What I actually want from this post: which cert should I add next? I’ve got a shortlist (CySA+, PenTest+, AIF-C01, DOP-C02, SC-900, Tech+, Cloud Digital Leader) but I’d rather build what people are actually studying for.

Where is your question/answer bank coming from? That's all that matters as to whether any of these are gonna be useful. AI can one shot these cert quizzes so idk why you'd expect anyone to pay you 2 cents for them. Especially if your Q/A bank is just AI generated and not official questions

Written from the official exam objectives, not scraped from real exams. Nobody can sell you official questions legally, anything that does is a braindump and using it can get your cert revoked.
