BulletFlight

Im surprised there arent a lot more reviews on this calc. as its pretty prolific in competition and field use.

Ive been using this app for a few years with no problems at all. As with anything, the quality of information you get OUT of this is 100% dependent on the quality of information you put IN. Your atmospherics dont have to be dead nuts on but your going to want an accurate station pressure and temp/humidity.

This will get me within a few tenths at 1000 and closer... Ive not used it past 1K and can not speak on the accuracy of either the wind drift or Coriolis compensation.

5 stars easily...
