Navigator (Mapfactor’s) is an Android navigation app what I thought it is the best of world wide supported with Open map. And now I am doing translate work for them as volunteer with no fee. (even also donated with IAP to them)
I latest translate, I could find something new words related in new In App Purchases a.k.a Premium functions to removing advertisements, OTIS server and HUD (head up display on your windshield).
I don’t know how much priced to removing ad. or HUD, but it will not for Koreans, because many Korean navigation apps already supporting all functions in 100% free for Androids and iPhone/iPad, already.
