# Device System Services vs FireWall Security

The clearest difference is review sentiment: FireWall Security at 100% against Device System Services's 52%. FireWall Security also leads on in-app purchases (none vs 1) and ads (none vs shown). Device System Services's advantage is rating (4.5 vs 4.1) and update cadence (every 4 months vs every 19 months). On price and device support there is nothing between them.

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

Device System Services holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Device System Services has 392 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 52% of Device System Services's written reviews are positive against 100% of FireWall Security's, so the app with the better star average is not the one people write more warmly about.

Device System Services ships an update every 4 months, FireWall Security every 19 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
