This gives a host of aviation performance calculation tools.

I literally bought this app to save time doing the weight and balance calculations but they are not in this the app. Can I get my money back?

The calculator does what you’d expect, but it’d be nice to have a toggle to see the conversion factors and formulas used for some of the calculations for reference.

Lots of little bugs unfortunately, double check if answers make sense before you fill out your navlog.

The = button on iPhone will scramble negative the number for the first tap, second tap will convert back to a close by number but not original number. I don’t know if it’s the calculation or Sporty’s ground school quiz answers are wrong. I got a different answer (off by 20 feet) when calculating density altitude. I made sure to clear all history and continue to be off of the quiz answers.

I deleted the app and reinstalled it to see if that would help. I enter the data but it produces nothing but zeros on the right side. This is a new issue. I hadn't previously had this issue seen it until about a week ago.

Version 3.4.5 when finding density altitude the App fills in the answer (appears to be correct) but when the = sign is pressed an incorrect answer is displayed. I don’t trust the app. I expected more from sportys.

Your so cool you make school fun

Great calculator/app. Use it all the time. Very user friendly!!

While completing some tasks it gives the correct answer without hitting the “=“ key. Which is handy, however, when hitting the “=“ key the app fails and kicks you out. Other than that it’s a great resource.
