Time zone

This app dose not take care of the time zone in the calculation. Which makes it useless unless you are in the same time zone

Great app! Sunrise/sunset and twilight times are very accurate. Calculation of night flight time also appears to be very accurate. Easy data entry for calculations. If you are a pilot and looking for an app to calculate your night flight time based on out/in times, look no further.
