Hi, I am looking for a special navigation app that tells me how tight corners are before I get to them so for example before I get to a tight corner on a country road I want it to say something like "90 degrees left in 100 meters". I need this app because I enjoy riding fast along country roads on my motorcycle but since 99% of the corners are impossible to see around since there are large bushes everywhere it can be quite dangerous. I could just mount my phone to my handle bars so I can see how tight the corners are on the map but I'd rather hear it through my ear phones.
