Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
E3/E4 TAG Heuer Connected holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: E3/E4 TAG Heuer Connected has 8.2K ratings behind it against 184, so its average is the more settled of the two. Written reviews complicate that: 59% of Kronaby's written reviews are positive against 49% of E3/E4 TAG Heuer Connected's, so the app with the better star average is not the one people write more warmly about.
Kronaby ships an update monthly, E3/E4 TAG Heuer Connected every 5 weeks. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
