Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SysStats Lite holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: ActMonitor has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of SysStats Lite's written reviews are positive against 75% of ActMonitor's, so the app with the better star average is not the one people write more warmly about.
SysStats Lite ships an update every 3 months, ActMonitor every 2 months. The most recent releases landed on October 2, 2026 and October 17, 2026 respectively.
