What Our Users Say
Don't just take our word for it. Here's what our users have to say about our Android app.
"Nice easy to use fuel converter app. If you could add a us gallon conversion that would be great."
jo bonfil
"Great app, Love that I can make adjustments for fuel gravity. Would love to have the ability to divide for each wing or tank, to show how much per side for weight and balance. UPDATE: Yes this saves me time but having to pull up a calculator to figure out how much per wing is time consuming and figuring in my head has led to some miscalculations. Still I love the app just need it to figure amounts per wing or tank."
Jesse Mahan
"Simple.... Seems to work!"
Randy
"This is a great app. I've gotten nearly the exact fuel quantity. Any way to add the SG for more accurate calc? Update... Now, works like a charm. Make refueling GA really simple. Kilo, to USG and vice versa. Great app!"
Brendan H
"SG now works backwards. Shows 10 USG to be 51kg for example. So currently unusable. Otherwise would be nice. You could also add in possibility to give currwnt fuel and desired fuel in different units. This is needed when dipstick is in USG and calculqtions done in lbs for example."

"SG now working goog"
Igore Mad
"Sorry, but have to say this shouldn't be used as there is no ability to set an uplift S. G."

"Good"

"I ran across this and wanted to give some feedback. I'm not a pilot, I'm a trucker that delivers aviation fuel for a living. Just wanted to let you know it's a great program, but the lb/gal values are off a bit (heavy). 100LL is about 5.5-6 lb/gal, and Jet-A is about 6.7. Great app!!"
Trent Eckhardt
"Great App, would also like to see changeable SG & percentage upload error if possible. Thanks"
