Fuel log and mileage tracking app for Android

Consumption chart not working
Hi all. I am using the Greek language version, i have added some fillup data and the first and last chart are empty. No consumption data or cost per km. All the other charts appear fine.

Cost per mile doesn't make sense
Not sure how it is calculated. Just spent $189.72 to fillup after 455 miles.
Cost per mile in app shows $0.402/mile
I think it should be $0.417 /mile
Am I missing something?

Upload pdf documents and not just jpg
Is there a reason why we can only upload an image from gallery to cost logs? Many invoices/receipts that we receive over email are in pdf form.

Question
hello
Thanks for the great app however I have a question. I am using a bi-fuel car (petrol and Lpg). Say that I filled up my lpg and drove 392km. At 300km the Lpg is finished and for the last 92km I used petrol. While entering the Lpg input during buying Lpg, should I click on the "missed previous fill-up tickbox or just eter the mileage value that needs to be excluded?

Fuel stations - Adding CNG price
Hi,
When I want to add the price of CNG to a fuel station, the added price is incorrectly labeled as LPG instead of CNG.

Option to either enter price per litre or full price and not both
Current behaviour: You can enter price/l or the full price and the other data is automatically calculated
My Usage: I always only enter full price, I don't want to enter price/l ...
Assumption: I think most users will only use one of them, some will enter full price, some only price/l. Normally they won't change their behaviour.
Proposal: Make an option in settings to choose between: full price, price/l, both.
If only one is choosen the other item will still be calculated, but disabled and also jumped over if you send "enter". It would be a little bit faster for those which enter "full price", as price/l will be jumped over and avoid errors (Today I was accidentially entering the full price in price/l field)
Thanks!
