Both are free to download. System Activity Monitors sells 4 in-app purchases, starting at $3.99 per 7 days and Device Settings Information sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Device Settings Information holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: System Activity Monitors has 778 ratings behind it against 117, so its average is the more settled of the two. Written reviews complicate that: 76% of System Activity Monitors's written reviews are positive against 60% of Device Settings Information's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

System Activity Monitors ships an update every 3 months, Device Settings Information every 4 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
