# Z Control vs NaviLink

The clearest difference is rating: NaviLink at 4.2 against Z Control's 2.4. NaviLink also leads on ratings volume (858 vs 67). Z Control's advantage is review sentiment (23% vs 11%) and iOS requirement (12.2 vs 15.0). 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.

NaviLink holds the better App Store score, 4.2 against 2.4. That said, the two scores are not equally well evidenced: NaviLink has 858 ratings behind it against 67, so its average is the more settled of the two. Written reviews complicate that: 23% of Z Control's written reviews are positive against 11% of NaviLink's, so the app with the better star average is not the one people write more warmly about.

Z Control ships an update every 6 weeks, NaviLink every 2 months. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
