For me Google Maps is the best app there is.
I love sharing on google map because i can help people to make the right decision where to go during their trips
I like to make Google maps even better, my favorite thing is take photo of place i visited and uploaded to google maps, whether it is a restaurant, a beautiful view point and i write a review, a good or bad review, and some time i add some missing place, because many restaurant and local store in my city are missing, so people can come and uncovers about that place.
