Verdict

CompTIA A+ & Security + Prep holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: CompTIA A+ & Security + Prep has 2.2K ratings behind it against 50, so its average is the more settled of the two. Written reviews complicate that: 31% of CompTIA A+ & Security + Prep's written reviews are positive against 77% of Linux Basics's, so the app with the better star average is not the one people write more warmly about.
CompTIA A+ & Security + Prep ships an update every 5 weeks, Linux Basics every 2 months. The most recent releases landed on October 10, 2026 and October 12, 2026 respectively.
