# ActMonitor vs Device System Services

The clearest difference is rating: Device System Services at 4.5 against ActMonitor's 3.5. Device System Services also leads on ratings volume (394 vs 22). ActMonitor's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Device System Services sells 1 one-off in-app purchase. ActMonitor asks for nothing beyond the download.

Device System Services holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Device System Services has 394 ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 75% of ActMonitor's written reviews are positive against 52% of Device System Services's, so the app with the better star average is not the one people write more warmly about.

ActMonitor ships an update every 2 months, Device System Services every 4 months. The most recent releases landed on June 11, 2026 and September 19, 2026 respectively.
