Flight Nav vs FlightFlux

Most airplanes don't have inflight information systems. If you ever wonder where you are, your altitude, ground speed, direct distance to your destination in Miles, Nautical Miles and Kilometers, and how many hours you still have to get there, this app will help you! 
 
Flight Nav uses GPS signals while in Airplane Mode to display your position, estimated distance, and time to your destination. You can record your flight and later share it as a GPX file. This option will consume more battery as it will operate even while you are not using your device. Other features include a "Don't sleep" feature to keep the screen on. 

GPS reception from within an aircraft can sometimes be poor. Best results are with window seats, or close to them, and you might have to wait longer to get results than you would while on the ground. What this means is that you might not get any signal at all, and the app might not work as expected every time, especially if you're sitting in the middle seats of a wide body airplane. Map detail will not be available at every zoom level - since you will be running offline - and you should use the app before flying, while still connected, in order to cache map information. 

You should only use your device when allowed by the cabin crew - Please, pay attention to the specific instructions regarding mobile devices. If you have doubts about using your device, even with Airplane Mode enabled, please consult the cabin crew.

 You can add your own destinations by long pressing the map on the location you want. Continued use of GPS can dramatically decrease battery life.
