# Web Inspector vs Device System Services

The clearest difference is rating: Device System Services at 4.5 against Web Inspector's 2.9. Device System Services also leads on update cadence (every 4 months vs every 22 months) and ratings volume (394 vs 30). Web Inspector's advantage is in-app purchases (none vs 1). On price, review sentiment, ads and device support there is nothing between them.

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

Device System Services holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: Device System Services has 394 ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 56% of Web Inspector'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.

Web Inspector ships an update every 22 months, Device System Services every 4 months. The most recent releases landed on August 15, 2026 and September 19, 2026 respectively.
