About CISSP
CISSP covers the eight domains of the ISC2 Common Body of Knowledge, from security and risk management through software development security. It is a management-level exam: the right answer is usually the one a risk owner would choose over the most technically clever one. You drill that judgment on 320 practice questions.
What you get
Scenario and PBQ-style practice
Use original categorization, ordering, matching, and scenario activities where included. They are study exercises, not official questions or exam simulations.
Domain-organized lessons
Study material is organized around the exam or legacy blueprint named on each page. Check that app's scope note and the certifying body's current objectives.
Flashcards & glossary
Drill acronyms and key terms with tap-through flashcards and a cross-linked glossary.
Weak-spot tracking
Questions and cards you miss come back more often in later sessions.
Works with no signal
Bundled lessons and practice work without a signal. App Store product loading, buying, and restoring require a network connection.
One-time unlock
A non-consumable App Store purchase unlocks the paid features. The App Store shows the current localized price; there is no subscription.
- Works offlineCore content and features remain available without a signal after any required download or purchase.
- No online accountNo sign-up, login, cloud account or account-based sync.
- One-time unlockA single non-consumable purchase, not a recurring subscription.
Common questions
What do I get before paying?
A free sampler of lessons plus a limited practice quiz, so you can judge the writing before you spend anything. The remaining lessons, the full question bank, the timed practice mode and the complete flashcard deck are behind the one-time unlock.
Is it a subscription?
No. One non-consumable in-app purchase unlocks the app permanently. It is not a recurring subscription, so there is nothing to cancel.
Do I need an account or an internet connection?
There is no app account, sign-up, login or account-based sync. Lessons and practice content are bundled for offline study; loading, buying or restoring the App Store unlock requires a network connection.
I paid and the app still shows the paywall.
Open Settings inside the app and tap Restore Purchases while online. That asks the App Store to re-check the current entitlement. If it still does not unlock, contact support with the app version, iOS version and exact error message; never send an Apple Account password or full payment details.
Does this replace the official study materials?
No. It is a study companion built to be used alongside the official objectives and hands-on practice. It is not affiliated with any certifying body.
