# ISC2 Official Exam Prep vs CompTIA A+ & Security + Prep

The clearest difference is review sentiment: ISC2 Official Exam Prep at 69% against CompTIA A+ & Security + Prep's 31%. ISC2 Official Exam Prep also leads on device support (4 vs 2). CompTIA A+ & Security + Prep's advantage is rating (4.7 vs 4.4) and ratings volume (2.2K vs 441). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ISC2 Official Exam Prep sells 5 in-app purchases, starting at $5.99 per 7 days and CompTIA A+ & Security + Prep sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

CompTIA A+ & Security + Prep holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 441 and 2.2K respectively. Written reviews complicate that: 69% of ISC2 Official Exam Prep's written reviews are positive against 31% of CompTIA A+ & Security + Prep's, so the app with the better star average is not the one people write more warmly about.
