The very niche-but-popular-in-its-field fuel helper is back! 
A minor but nonetheless useful app update. Mainly the addition of the 'fine adjust' buttons for the specific gravity. It's been cold and I've been wearing gloves, I noticed that it was rather fiddly getting the SG slider to land exactly on the spot I wanted it. So now you can nudge the SG up or down by tapping the Fine Adjust buttons. Each press moves the SG up or down by 0.01 (To the casual reader 0.01 might not sound much but when fuelling and A380 it could make all the difference!)
