# bOS Client vs Ajax Security System

The clearest difference is review sentiment: Ajax Security System at 73% against bOS Client's 29%. Ajax Security System also leads on update cadence (fortnightly vs every 3 months) and ratings volume (270 vs 2). bOS Client's advantage is rating (5.0 vs 4.3) and iOS requirement (13.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

bOS Client holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Ajax Security System has 270 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 29% of bOS Client's written reviews are positive against 73% of Ajax Security System's, so the app with the better star average is not the one people write more warmly about.

bOS Client ships an update every 3 months, Ajax Security System fortnightly. The most recent releases landed on August 16, 2026 and September 23, 2026 respectively.
