【實用交通運輸app】GPS-Altimeter|最夯免費app-綠色工廠好玩App

The best integrated altimeter and map app for the iPhone! Now even older devices can enjoy having directional markers on your maps!Using the built-in GPS hardware, and beautiful graphics, the app displays your current altitude in both meters and feet. Simply touch the display to toggle between units.In addition to the altimeter feature, the app makes it simple to switch between the altimeter display and an enhanced map view that integrates the direction you are facing.For users with older iPhones without a built-in compass: this app will determine the direction you are facing based on GPS readings taken while you are moving. The app takes this reading and allows you to see the direction you are heading on a Google map. You can also choose to rotate the map so your direction is always shown straight ahead…this capability was previously only available to 3GS owners with a built in compass!For newer devices with a built-in compass: this app uses the more accurate hardware to improve the existing compass and map apps on your device by allowing you to see the direction you are facing directly on the map while keeping the top of the map facing north. In other words, the directional cone on the map will rotate, not the map itself, if you like.Please note, this app is made to work with the GPS capabilities of the iPhone 3G or 3GS. Models without GPS will probably not work. Models with GPS but without a compass will need to be moving in order for your heading on the map to be determined.
