Verdict
The clearest difference is rating: Mobile Master at 4.5 against CPU Identifier's 3.7. Mobile Master also leads on ratings volume (1.2K vs 7) and iOS requirement (12.0 vs 17.0). CPU Identifier's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and review sentiment there is nothing between them.

Both are free to download. Mobile Master sells 3 in-app purchases, starting at $0.49 per month. CPU Identifier asks for nothing beyond the download.
Mobile Master holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Mobile Master has 1.2K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 78% of CPU Identifier's written reviews are positive against 72% of Mobile Master's, so the app with the better star average is not the one people write more warmly about.
CPU Identifier ships an update every 2 days, Mobile Master every 6 days. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
