Latest update stopped recording my study question results, so I can’t review what answered incorrectly. And, a useful feature that roughly gauged how the community faired on a particular question. The update has made the app objectively worse. ### 4/5 — Update broke Multiple Answers Questions *2026-04-27* Since the latest update, when clicking on one answer in a question where multiple are allowed, the answer is immediately shown me my answer marked as wrong as I was not able to click on all. That’s the same on iOS and android. **Developer response:** Thanks for reporting this — we really appreciate it. This issue with multi-answer questions being auto-submitted after the first selection has been identified and fixed. Please update the app to the latest version, and it should work as expected now. If you still notice anything off after updating, please reach out to us at support@learnzapp.com with details — we’ll take a closer look right away. ### 4/5 — Good app with room for improvement *2026-03-07* Overall a very helpful app for studying, though I highly suspect some of the questions have incorrect answers. Here’s what I propose to improve this app: 1. Add an option to flag a question for official review. It’s one thing to have a hard question that we want to flag to study later, but as noted, some questions simply seem wrong and it’d be great to have someone who CISSP-certified review such questions for accuracy. 2. Clarify what is meant by the domain progress bars: is that the percent of questions answered, percent answered correctly, or something else? I’m unclear and those are two very different things. 3. Minor thing, fix the typos in the questions. The word “an” is often missing a space after it. An option to randomize both the order of the questions, and their answers, would be great. Looking forward to seeing these improvements; this app is pretty good far. Keep up the good work devs! ### 3/5 — Well designed but … *2025-11-14* It’s a really well design interface, it operates off-line so you don’t have to be connected to Wi-Fi, and it’s really helpful to have a glossary and all the tools available when you’re studying. The one thing I don’t understand is the readiness score is based off of its total number of questions that you’ve answered right versus the one you’ve answered wrongrather than an evaluation of your ability to assert solutions that work across domains. It’s very much focused on reviewing individual questions about each domain rather than into relating those much like you would see on the more expensive practice test platforms. ### 4/5 — CISSP content to update *2025-11-12* Just passed the CISSP certification today and the quiz needs to be refreshed. The exam is now far less focused on the deep technical aspects (crypto, networks…) Otherwise the app in itself is good with clear interface and reporting on progress. ### 5/5 — I love this app *2025-10-02, version 24* Thanks ### 5/5 — Great App *2025-07-19, version 24* Easy to use, highly recommend ### 5/5 — Best app to study CISSP *2025-07-08, version 24* This app makes studying a breeze. The readiness score it provides makes it easy to determine and touch up on weak areas. ### 5/5 — Great tool for studying! *2025-06-25, version 24* Love this app. Worth it! ### 4/5 — Great product if studying for CCSP *2025-06-22, version 19* Clean UI with comprehensive coverage of subject matter. ### 5/5 — Must have for CISSP exam preparation *2025-06-11, version 24* Yes, you can use the practice tests that come with the official study guide BUT this is so much easier AND allows you to focus on domains you may be weaker on. Do yourself a favour and get it. ### 5/5 — Passed the CCSP *2025-06-03, version 24* While I do think there needs to be more frequent updating and review of the content here. I thought it was a great tool to help prep for the test. ### 5/5 — Recommend it great *2025-05-25, version 24* Decent does what it says on the tin ### 5/5 — Learnzapp is awesome for study *2025-05-23, version 24* I used this app everyday for preparing to take the CISSP and CCSP exams, I think that practice tests and exams help by making the studying process as close to the test process as possible. I highly recommend! ### 4/5 — My Review *2025-05-01, version 24* I have very good experience with learnzapp. The question bank helped a lot to understanding in detail explanations for each question and each section with score levels indicating . The question are mostly medium and average. Not too much hard questions as based on comparing to the real exam. ## Most critical reviews (10 lowest-rated) ### 1/5 — Mid *2026-03-04, version 24* Hard to use ### 1/5 — Crashed when I tried to subscribe *2026-02-12, version 24* I’m using on my iPad. Every time I tried to subscribe the service it crashed the app. Thus I have relaunched again to use the free version. ### 1/5 — Repetitive and not accurate questions *2025-07-25, version 24* This app has the same questions as the book. Also if you bought the practice exams then the same questions are here. Not sure where they got 5000 questions as if you add what they have is about 3000. The app is ok but it doesn’t let you mix questions randomly to create practice test ### 1/5 — Undecided if helpful or hurtful *2025-05-22, version 24* I’ve been warned to not use this app as a resource as it’s too easy. I’ve used this primarily, along side the official text book and official practice exams, but the content is pretty much the same, and the practice exam has the same questions as this app. I’ll update this review if it does happen to be helpful ### 1/5 — Data keeps getting cleared *2025-05-16, version 24* Dashboard keeps resetting ### 1/5 — Typos and mistakes *2024-12-30, version 24* This official app if full of typos and other mistakes. For the price I expect much higher quality. ### 1/5 — Crash on iPad (18.2) *2024-12-19, version 24* Crash,pls fix ### 1/5 — Keeps crashing *2024-12-07, version 24* Try to purchase a premium plan, crashes. Finish a flashcard deck, crash. No clue if the app is even worth it. ### 1/5 — Questions are nothing like exam *2024-11-21, version 19* This will not prepare you for the exam. The study questions are absolutely nothing like the exam. This is one of the worst resources for studying. ### 1/5 — Had 95% readiness scores yet I failed the test *2024-11-03, version 23* Total waste of money and time ## Most praised reviews (10 highest-rated) ### 5/5 — Great for technical *2026-06-28, version 30* Heat for technical. However, not great for least, most, or preparing to THINK like a manager. ### 5/5 — Passed! *2026-05-20, version 28* I found this app and the support team extremely helpful in getting ready for the exam. Highly recommend. ### 5/5 — Perfect for exam preparation *2026-05-18* Pretty useful when preparing for the exam. **Developer response:** Thanks, glad it's helping with your prep! Wishing you the best on exam day. 💪 ### 5/5 — Good as learn Support *2026-04-17* Nice app **Developer response:** Thanks so much — glad you're enjoying it! If there's ever anything that would make it a 5-star experience for you, we'd love to hear it at support@learnzapp.com. Best of luck with your prep! ### 5/5 — Best Study app for CISSP *2026-03-14, version 24* I’ve looked at a few apps to help me study, and this isn’t far the best. I love the ‘Qujck Set (10)’ feature - it’s ideal to use spare moments to study effectively. ### 5/5 — Great for reinforcing concepts *2026-02-20, version 24* This is a great app with test that will help you reinforce concepts you have learned. It also gets you used to dealing with scenario based questions. Many practice questions and test options to help you prepare, the readiness score is also a confidence booster or an indicator to study more. ### 5/5 — My main training resource *2026-01-20* It is a great app for laying the foundation of the CISSP certification knowledge. However, the questions are not written in the style of the actual exam, so you cannot rely on this app alone. Real exams require careful, word-by-word reading and the ability to prioritize and eliminate misleading answers. Unfortunately, such exam-style questions are sorely missing. ### 5/5 — Great learning app *2025-12-22, version 24* This app, helped me realise my knowledge weaknesses and is helping to remove them. Great app. ### 5/5 — Best Study App Ever *2025-11-25, version 24* Thank you creators of app. The custom test was the kicker out of the ball park. Highly recommend this app for studying for the CISSP! ### 5/5 — Studying for cissp *2025-11-09, version 24* Love this app paired with using the OSG --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
