New ! Now supports fixed speed cameras and inner city limits

Speed Limit App displays the current speed limit and your current speed. It detects European speed limit signs using the camera while driving and enhances the results by map based limits from OpenStreetMap. Thus it will even know limits which are not indicated by signs (i.e. Zone 30, or inner city areas). Of course it will warn you when you are too fast.

► Working principle of Speed Limit App
Speed Limit App is a road sign recognition app. For inner city limits we use map based information from OpenStreetMap. Both information is merged to provide an optimal limit indication. The speedometer gets its data from the GPS and is used to determine wether you are above or below the actual limit of the last detected road sign.

► Limitations of Speed Limit App
Speedometer Radar Camera does a computational intensive job that formerly was limited to mainframes. Therefore there are some restrictions:

- At night and in adverse lighting conditions the recognition of road signs might fail due to iPhone camera limitations.
- The app is optimized for European road signs. Unfortunately there is yet no support for US speed limits.
- There is no support for 'end of limit' signs yet and no support for place/city signs that might also decrease the speed limit according to local traffic road regulations.
- Sometimes road signs in narrow turns are missed due to the limited view angle of the camera
- Sometimes there are missed or false road sign detections
- Speedometer is updated every second

Great app

Tried many apps this one’s the best


Not worth the cost

Requires constant fiddling with it, creating a serious driving hazard. Frequently missed plainly visible speed limits. Sometimes funny: 100 Kph read as 10 Kph, other times less funny: left turn sign read as 70 Kph and right turn sign read as 50 Kph.

I only purchased because the first couple of minutes the program seemed fine, and then was CONSTANTLY blocked with ads. So I took a chance. In under five minutes I realized it was a mistake to pay for the app.

Thanks for this great app. It would be nice to be able to select the signs to be detected. For example, I am only interest in detecting STOP and YIELD signs. The detection speed is kind of slow on my iPhone 11. Maybe reducing the number of signs to detect could improve the sign detection speed?
