I’ve been using this App for the last 5 years and since the last update it is a complete wrong App. The last calculation, for only 6700 lbs of uplift, gave me 8375 Lts required fuel (SG 0.8). Completely wrong and useless. If you don’t fix all this, if the App is not maintaining last values I’d delete it. After 2 months of above comment, the App is not working well. Thank you but I’ll look for another one. Bye
