What's New in WiFi Coverage Survey & Heatmap
1.2
October 15, 2026
WHAT'S NEW IN 1.2 • The survey keeps measuring while you check the other tabs; on iOS 26.1 and later a tab bar accessory shows its live state and takes you back. • On iOS 26 the system's own link quality verdict is shown next to the PHY mode and included in exports. It does not affect the score. • The gateway iOS routes through is tried first, so the right router is found faster; a manually entered address now holds until you join another network. • The TCP probe counts dropped connection attempts more accurately. • Refreshed App Store listing with new screenshots. After a completed survey the app may ask you for a rating, at most once per version.
