It is a web app developed by myself in Technology Innovation Competition.


The purpose of the app is to recognize a Traffic Sign quickly by using mobile phones or PCs. I like go hiking and often enounter some weird traffic signs I don’t know.

Now this app had been shut down because of no fees to maintain it.
