# Service Inspector vs Kaiten

The clearest difference is review sentiment: Service Inspector at 80% against Kaiten's 22%. Service Inspector also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 15.0). Kaiten's advantage is rating (3.3 vs 2.1) and update cadence (every 5 days vs every 3 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Kaiten holds the better App Store score, 3.3 against 2.1. Both are backed by a comparable volume of ratings — 7 and 9 respectively. Written reviews complicate that: 80% of Service Inspector's written reviews are positive against 22% of Kaiten's, so the app with the better star average is not the one people write more warmly about.

Service Inspector ships an update every 3 weeks, Kaiten every 5 days. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
