# DoorBird vs Ajax Security System

The clearest difference is review sentiment: Ajax Security System at 73% against DoorBird's 37%. DoorBird's advantage is ratings volume (29K vs 270) and rating (4.5 vs 4.3). On price, update cadence, 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.

DoorBird holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: DoorBird has 29K ratings behind it against 270, so its average is the more settled of the two. Written reviews complicate that: 37% of DoorBird'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.

DoorBird ships an update every 3 weeks, Ajax Security System fortnightly. Both last shipped on September 30, 2026.
