I’ve also used CoMaps and love it. I occasionally go to places that use non-Roman alphabets, and Organic Maps and all the other maps using OSM maps always always always suck at things like addresses and romanization of the alphabet. CoMaps seemed to do it just fine, so that alone sold me.
Its directions don’t include any traffic data, so it’s obviously not at the level of Waze or even Google maps. The “shorter route” might lead you straight into 3 lanes of bumper-to-bumper traffic. But all things considered, love it so far.
Right now, I can’t justify using Organic Maps because it is just not usable enough. 99% of my navigation involves searching for place names and navigating with turn by turn directions which never seems to just work with Organic Maps. If I am on the interstate driving across country, I want to be able to search for a Chiotple or Fast Food or something along my route. I can’t search for addresses in a clunky interface. I am not sure if I am missing something, but I use Waze even against my privacy judgments.
