CISSP Exam Prep & Questions
Education
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Every explanation names the official document it came from, so you can check us instead of trusting us. 450 original questions and 23 concept diagrams.
Most CISSP prep apps ask you to trust them. This one asks you to check.
Every explanation ends with an Official reference card. Its title is read off the link it opens, with the address printed underneath, so the card can never name one document and open another. The exam domain sits outside the card, labelled as this app's own mapping rather than a quotation. If the reasoning is wrong, you can prove it. That is the whole product.
WRITTEN, NOT SCRAPED
450 original questions, written against the current ISC2 CISSP exam outline and weighted across its eight domains. These are not real exam questions and not dump site material. Memorising leaked items does not build the judgement this exam tests, and it puts your certification at risk. Citations point to ISC2, NIST, ISO, OWASP and the other bodies that actually publish the standards, never to a forum post.
BUILT TO FEEL LIKE THE REAL THING
The real exam is computer adaptive: three hours, 100 to 150 items. The mock here is a fixed sitting of 150 questions on a single 180-minute clock, the exam at its longest form, drawn from each domain in proportion to its weight. The clock pauses while you read an explanation and ends the sitting when it reaches zero. Options are reshuffled every time a question opens, and correct answers are length matched against the distractors, so neither position nor verbosity gives it away.
ABOUT THE PASSING SCORE
ISC2 reports a scaled score out of 1000 with 700 required to pass. That score comes from an adaptive model that weights items by difficulty, not from counting correct answers, so no practice percentage converts into it and this app does not pretend otherwise. What you see here is this app's own readiness target of 70 percent, labelled as exactly that: a target for practice, not an official pass mark.
DIAGRAMS WHERE WORDS RUN OUT
23 concept diagrams cover the genuinely spatial material, from web app trust boundaries and PKI trust chains to network zones, access control models and the incident response lifecycle. They appear on 192 of the 450 questions and are drawn in the app, so they stay sharp and readable in both light and dark mode.
EXPLANATIONS IN FOUR PARTS
Why the correct answer is correct. Why each wrong option is wrong, individually rather than as a group. The exam trap the question was built around. The official reference.
COUNTED BACK FROM YOUR EXAM DATE
Set the day you sit and the home screen becomes a plan: days left, a target for today built from what is unseen plus what is due, and whether your rate closes the gap. Pace counts questions met for the first time, not raw answers. Under ten answers it shows no pace. When days are too few it points you at the heaviest material and one full mock instead of the whole bank. It plans coverage, not scores.
Spaced repetition brings a question back a day after you first get it right, then after 3, 7, 14 and 30 days, stretched or tightened by how reliably you answer it, and dropped back when you miss. With an exam date set, nothing is scheduled past the day you sit. Weak domains surface on their own, and two stage hints unstick you without naming the option.
WORKS OFFLINE, NO ACCOUNT
The entire question bank ships inside the app. No sign up, no server, nothing to sync.
PRICING
One whole domain is free: all 70 questions of Security and Risk Management, with no daily or time limit. Explanations, diagrams and citations behave exactly as they do everywhere else, so you can judge the bank before deciding. Premium opens the remaining seven domains, 380 more questions, and full length mock exams, for US$19.99/month or US$69.99 once for lifetime. Your local price is shown before you buy.
We make no claim about your result. No app can promise a pass.
