# ABUS Z vs SkyBell

The clearest difference is review sentiment: SkyBell at 41% against ABUS Z's 12%. SkyBell also leads on ratings volume (12K vs 1). ABUS Z's advantage is rating (5.0 vs 4.7) and iOS requirement (8.0 vs 15.1). 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.

ABUS Z holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: SkyBell has 12K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 12% of ABUS Z's written reviews are positive against 41% of SkyBell's, so the app with the better star average is not the one people write more warmly about.

ABUS Z ships an update every 3 months, SkyBell every 2 months. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
