Speed Limit App – Smarter Speed & Road Sign Detection ! It shows your current speed and the current speed limit at a glance. It uses advanced camera-based traffic and road sign detection to recognize European speed limits in real time, and enhances accuracy with map-based data from OpenStreetMap. This combination gives you highly reliable speed limit information—even when signs are missing, such as Zone 30, inner-city areas, or other implicit limits. And of course, you’ll get a clear warning when you are going too fast. ► New in the Latest Version • NEW! CarPlay Support – See your speed, limits, and detections directly on your CarPlay dashboard. • Redesigned Road Sign Detection – More accurate, faster, improved performance for all European road signs. • Ultrawide Camera Support – Capture more of the road ahead for improved detection of traffic signs in curves or at the roadside. • Improved Speedometer Design – Cleaner, more modern, and easier to read at a glance. ► How Speed Limit App Works Speed Limit App is a powerful road sign recognition tool using a hybrid detection method: • Camera-based recognition: Detects European speed limit signs using your iPhone’s camera while driving. • Map-based detection: Retrieves speed limit information from OpenStreetMap for inner-city areas, zones, and roads without physical signs. • Both sources are intelligently merged to give you the optimal and most reliable speed limit indication. • The built-in speedometer uses GPS to determine whether you are above or below the actual limit of the last detected road sign. Perfect for avoiding speeding, spotting missed signs, and staying informed—whether by camera-based or map-based detection. ► Limitations of Speed Limit App Speedometer Radar Camera technology performs highly complex computer vision tasks — something once limited to mainframe computers. Therefore, some limitations apply: • In low-light or adverse weather, the iPhone camera may fail to recognize certain road signs. • Optimized for European road signs only, US speed limits are currently not supported. • No support yet for “end of limit” signs or town/city boundary signs that may influence speed limits in some countries. • Road signs in narrow turns may be missed due to limited camera visibility. • Occasional missed or false detections may occur. • Speedometer updates frequently. ► Notes from the Developer If you like Speed Limit Warning Camera, please consider rating the app. If you have suggestions or feedback, feel free to reach out via email. To enjoy an ad-free experience, consider the optional in-app purchase—developing an app with advanced traffic sign detection takes time and expertise that we hope you’ll support. ► Disclaimer The author assumes no liability for any damages occurring in connection with this app. Use is entirely at your own risk.

Verdict
The clearest difference is rating: Speedometer Limit Camera at 4.6 against Ray.Radar Detector's 3.7. Speedometer Limit Camera also leads on ads (none vs shown) and ratings volume (531 vs 3). Ray.Radar Detector's advantage is update cadence (fortnightly vs every 3 months) and iOS requirement (12.0 vs 17.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Speedometer Limit Camera sells 4 in-app purchases, starting at $3.99 per 7 days and Ray.Radar Detector sells 10 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Speedometer Limit Camera holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Speedometer Limit Camera has 531 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 32% of Speedometer Limit Camera's written reviews are positive against 33% of Ray.Radar Detector's, so the app with the better star average is not the one people write more warmly about.
Speedometer Limit Camera ships an update every 3 months, Ray.Radar Detector fortnightly. The most recent releases landed on September 21, 2026 and September 8, 2026 respectively.
