JJ Map

JJ Map is free navigation app and GPS app. It features turn by turn directions. There is also bookmarking locations and public amenities. The app helps you to find any shop at Chatuchack Weekend Market located in Bangkok Thailand. It's about as close to a Google Maps competitor as it gets. It should work for most people most of the time. Some have reported some issues here and there, but nothing overly worrisome. The app is completely free with no in-app purchases.
