It has no voice turn by turn directions. How can an app be called a navigation app without that? It has a premium feature to turn sound off even though there are no sounds so maybe it's planned for a future release? It doesn't have much of anything else either. The premium version has a dashcam, which could be interesting. There are a couple other premium features that have no explanation of what they do. So maybe it has some usefulness, Idk. But currently, I can't find any reason to use it.
