Flight Nav vs PikFly

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.

Your flight, as live telemetry. PikFly reads raw data from your phone's GPS receiver and turns it into a clear, instrument-style display: where you are, how high, how fast and where you're heading. Everything works in airplane mode. No Wi-Fi, no roaming, no account. WHAT YOU SEE • Below you: city, region and country, or the name of the sea or ocean you're crossing • Altitude, ground speed and track, with a climb/descent indicator and a cockpit-style heading tape • Nearby airports: distance, direction relative to the aircraft and time to reach them when you're heading their way • Local time below you, compared with your phone's clock, so you know when you've crossed a time zone • Sunrise and sunset corrected for cruising altitude (from 11 km up, the sun sets later than on the ground) • Moon phase and position • Offline world map with borders, seas, cities, airports and your track BUILT FOR THE AIR • 100% offline: the map, 9,500 airports and 34,000 cities are built into the app • Your location never leaves your device. No tracking, no ads, no sign-up • Metric, aviation (ft, kt, nm) or imperial units • Keeps the screen on while you follow your flight • Demo flight mode to try it out on the ground • English and Polish TELEMETRY BY PiK SYSTEMS PikFly is made by PiK Systems. Telemetry is what we do: collecting data from sensors and turning it into information people can read at a glance. PikFly is a small, free showcase of that idea. The phone in your pocket is the sensor, and the sky is the test bench. TIPS Sit by the window and keep the phone close to the glass. The first GPS fix in airplane mode can take 1 to 5 minutes. PikFly is not a navigation instrument.
