# Smartlink Security vs Z

The clearest difference is rating: Smartlink Security at 2.3 against Z's 1.6. Smartlink Security also leads on ratings volume (103 vs 5). Z's advantage is review sentiment (20% vs 9%). 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.

Smartlink Security holds the better App Store score, 2.3 against 1.6. That said, the two scores are not equally well evidenced: Smartlink Security has 103 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 9% of Smartlink Security's written reviews are positive against 20% of Z's, so the app with the better star average is not the one people write more warmly about.

Smartlink Security ships an update every 2 months, Z every 3 months. The most recent releases landed on September 21, 2026 and June 10, 2026 respectively.
