# SYSMonitor vs Mobile Master

The clearest difference is rating: Mobile Master at 4.5 against SYSMonitor's 3.6. Mobile Master also leads on review sentiment (72% vs 40%) and update cadence (every 6 days 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 Mobile Master sells 3 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.

Mobile Master holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Mobile Master has 1.2K 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 72% of Mobile Master's.

SYSMonitor ships an update every 5 months, Mobile Master every 6 days. The most recent releases landed on September 29, 2026 and September 24, 2026 respectively.
