# SYSMonitor vs CPU Detector

The clearest difference is rating: CPU Detector at 4.6 against SYSMonitor's 3.6. CPU Detector also leads on review sentiment (76% vs 40%) and update cadence (every 2 months vs every 5 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SYSMonitor sells 1 one-off in-app purchase and CPU Detector sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CPU Detector holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: CPU Detector has 427 ratings behind it against 38, so its average is the more settled of the two. Written reviews point the same way: 40% of SYSMonitor's written reviews are positive against 76% of CPU Detector's.

SYSMonitor ships an update every 5 months, CPU Detector every 2 months. The most recent releases landed on September 25, 2026 and September 10, 2026 respectively.
