Imagine a world that's not completely and totally explored yet—sort of like in Warcraft where the unexplored terrain is dark because your character never went there. It exists in real life too. It's the own world you live in. You haven't seen everything or been everywhere so this app, Fog of World, makes the places you've already been completely clear and the unexplored places, foggy. As you go to new places, the map gets clearer. It looks so fun.

Not only does it motivate you to travel more (which is always a good thing) and see more and do more, it can also act as a great resource to keep track of the places you've been too. I haven't been this excited about an app since, I don't even know. If the battery drain isn't horrible, I'm definitely going to use this. $5 [iTunes via Fog of World]

★ Features
- Record where you have been using GPS-enabled iOS devices
- Locations are also recorded when app is running in the background
- Fog covers where you haven't been on the map (just like the Fog of War in strategy games)
- Show the percentage of area your have explored around the world, around a continent, or even around a country
- Support for importing GPX and KML files
- Support for sync and backup through Dropbox
- Integrated with the Game Center

★ Notes
- Apple Maps is used in iOS 6 and later.
- The app can also record your locations when running in the background. However, to save battery life of your iOS device, locations will be reported approximately every 40-50 meters when app is running in the background, and connected to the previously reported one. Therefore, no fog will be removed if you only move a few meters.
- The foreground app always has the highest priority in iOS, so iOS will close background apps when memory is not enough. This usually happens when you're playing a game. Make sure the recording mode is on before moving.
- Your locations will be recorded only when there are at least 3 GPS signal bars even though you entered the recording mode.
- Airplane Mode turns off GPS explicitly. Turn off Data Roaming or remove (or simply lock) your SIM card instead if you want to use GPS abroad.
- Internet connection is required to determine the corresponded countries of the recorded locations. A loading icon will appear on the top-left corner of the screen when this function is working.
- It is recommended to use a separate GPS device to record your tracks. This would save battery life of your iOS device and avoid GPS signal loss when Internet connection is unavailable.
- If you use an external GPS device, make sure the distance between two consecutive GPS points is less than 2 kilometers, or that part of track will be ignored when importing to the app.
- Continued use of GPS running in the background can dramatically decrease battery life.
