Verdict
The clearest difference is review sentiment: ISC2 Official Exam Prep at 69% against CISSP Exam Certification Prep's 20%. ISC2 Official Exam Prep also leads on update cadence (every 3 weeks vs every 4 months) and device support (4 vs 2). CISSP Exam Certification Prep's advantage is rating (4.7 vs 4.4) and iOS requirement (13.0 vs 15.6). On price, ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ISC2 Official Exam Prep sells 5 in-app purchases, starting at $5.99 per 7 days and CISSP Exam Certification Prep sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.
CISSP Exam Certification Prep holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 447 and 177 respectively. Written reviews complicate that: 69% of ISC2 Official Exam Prep's written reviews are positive against 20% of CISSP Exam Certification Prep's, so the app with the better star average is not the one people write more warmly about.
ISC2 Official Exam Prep ships an update every 3 weeks, CISSP Exam Certification Prep every 4 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
