Traffic Sign Camera helps you see your current speed and the detected speed limit at a glance while you drive. It combines live camera recognition with map-based speed-limit lookup from OpenStreetMap, then shows the result in a clear driving display with a GPS speedometer. ► Top Features • Live camera-based recognition of European speed limit signs. • OpenStreetMap speed-limit lookup for roads, city areas, zones, and places where physical signs may be missing. • Smart merging of camera and map sources into one overall speed-limit display. • GPS speedometer with color feedback when you approach or exceed the current limit. • Sound alerts for newly detected signs and overspeed warnings. • CarPlay support for viewing speed and limit information on your dashboard. • Configurable km/h or mph units, speed tolerance, warning threshold, camera mode, and map query interval. • Ultra wide camera support on compatible iPhones for a broader view of roadside signs. ► How It Works Traffic Sign Camera watches the road ahead with your iPhone camera, finds possible speed-limit signs with on-device machine learning, and reads the sign value with Vision text recognition. At the same time, it can use your current location and course to request map-based speed-limit data. The app combines both sources so you can keep your eyes on one simple limit display. ► Important Limitations Traffic Sign Camera is a driver assistance tool, not a replacement for your attention or local traffic law. • Optimized for European speed limit signs. US speed limits are not currently supported. • Poor lighting, bad weather, dirty windows, unusual signs, or narrow curves can reduce camera recognition quality. • The app does not currently detect every end-of-limit, town boundary, or special-case road rule. • Map data depends on OpenStreetMap coverage and an internet connection. • Missed or incorrect detections can occur. Always follow posted signs and local rules. ► Notes from the Developer If you like Traffic Sign Camera, a rating helps a lot.

ReceptionRating · Positive reviews · Number of ratings

Speed Limit Camera holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Speed Limit Camera has 530 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 32% of Speed Limit Camera's written reviews are positive against 83% of Bolt Speed's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 13, 2026 and September 24, 2026 respectively.
