Sennheiser Smart Control holds the better App Store score, 3.4 against 2.5. That said, the two scores are not equally well evidenced: Sennheiser Smart Control has 1.5K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 23% of Sennheiser Smart Control's written reviews are positive against 33% of Longines VHP GMT Flash Setting's, so the app with the better star average is not the one people write more warmly about.
Sennheiser Smart Control ships an update monthly, Longines VHP GMT Flash Setting every 2 months. The most recent releases landed on October 28, 2026 and October 22, 2026 respectively.
