Traffic Sign Camera detects traffic signs using the camera while driving. It displays your current speed along with the last detected speed limit. Color and sound indicate when you are too fast. This makes Traffic Sign Camera a very useful driving app. Currently it recognizes over 40 road signs.
It detects more than 40 traffic signs. Please have a look on the lefthand graphics showing which signs are supported.
Traffic Sign Camera uses the builtin GPS to show your current speed. You can set the tolerance at which the app emits overspeed warnings.
When you are entering a speed limit limit area you will be warned if you are too fast. Sounds are configurable.
You can configure many settings, including: overspeed tolerance, speed units (km/h or mph), auto clear timeout, auto clear distance and speed limits only mode.
We offer a free testing period. If you want to get rid of ads and unlock higher speed limits you can purchase a lifelong license (one-time payment).
The app is based on neural net technology. In order to detect signs in many situations thousands of images have been learned into the neural net. Sometimes the images from the camera are confused with known signs. This is inherent to this technology. Although we are committed to decrease the error rate, neural nets are not an error-free technology.
Press Setup to open the app configuration screen. There you can select overspeed tolerance and other settings. For further details please refer to setup screen description below.

This button opens the upgrade screen. You will be asked to log with your AppleID. This is only to renew previously made purchases. No purchases are made by entering your password on setup screen opening ! Here you perform your Pro upgrade or recover your previously made purchases. For further details please refer to update screen description below.
Please note that you can touch the speed limit display to clear the current speed limit.
The over speed tolerance is relative to the detected speed limit. If the current limit is e.g. 100 km/h and you set a overspeed tolerance of 10% you will be warned when going faster than 110 km/h. The speed display will change its color to yellow/red and you wil hear the overspeed sound, if you have configured one.
You can change between metric and imperial unit system for speed and distance measurements.
When you are not moving (e.g. before a red traffic light) you do not need to spend resources on sign detection. This is the reason why the app does not detect anything when not moving. For testing purposes however you can enable detection when standing sill. This will increase battery consumption and device heating.
If you are not interested in signs other than speed limits you can configure this here. If switched on only speed limits will be detected.
Press the purchase button indicating the price to purchase a life-long license for this app. It is a one-time payment which unlocks the higher speed limits and removes the ads.
Press this button if you want to restore previously made purchases. If you have purchased and did a reinstall or got a new device you have to restore by pressing this button.
All restore actions are for free, because you already have payed for them.
Traffic Sign 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 German traffic signs. However in many countries the signs are very similar and therefore the app should work there too. Unfortunately there is yet no support for US speed limits.
- There is no support for place/city signs that might also decrease the speed limit according to local traffic road regulations.
- Sometimes traffic signs in narrow turns are missed due to the limited view angle of the camera
- Sometimes there are missed or false road sign detections
