New ! Carplay Support, Redesign of Roadsign Detection, Ultrawide Camera Support, Improved Speedometer Design
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.

Have had subscription version for over 1 year. Glad I stuck with it after initially poor 1 star review. Latest version a major improvement, camera now functions on uk roads so giving greater responsiveness and accuracy. Will continue to use as a vital aid in trying to stick to the myriad changes of speed limits on modern roads.
Excellent!

This app is for anyone who can’t afford any more points on their licence. It’s very accurate and can read the variable digital gantry speed limits over smart motorways as well as normal speed limit signs. Absolutely brilliant. At night on streets without street lighting it won’t pick up most signs but the GPS puts the road speed limit in anyway so that doesn’t really matter. For those complaining about adds popping up, jeeeez just pay for the pro version.
Great concept Poor in actuality

Looking at the App it seemed the answer to my needs (2 speeding tickets in 4 days) so I downloaded, paid for the Pro and within a few miles I could see it’s limitations. Driving along a 30mph road the display says National Speed Limit. Luckily I’ve used this along roads I know the limits for. If I had no knowledge of them this App has shown it’s unreliable and that is unacceptable. The alarms are effective but do not repeat once you’ve transgressed. There needs to be better GPS & mapping to make this effective but until that’s done find other apps. Such a shame as it looked very good
Brilliant but flawed

I love this app, it is brilliant in concept and mostly so in execution. However, on my 15 Pro Max it misses about half of the speed limit signs and really struggles with the digital motorway overhead signs (in both wide and narrow camera modes). And imho the actual speed needs to be larger, and not red on black as this is difficult to read at a glance.
