Drop a pin on the map for all locations you want to remember, flag it as good or bad, and even add your own comment about it if you wish. This app even shows the number of miles away from your current location when you tap it. Whether it's that roadside hotel you stayed at, a food place you liked or disliked, friends house location, or gas station, you can mark it on the map so you always have it saved for future reference. The pin colors you mark on the map change colors based on whether you liked it or disliked it, and you can tap the pin to view your comments and current distance away.
