Fuel log and mileage tracking app for Android

Allow entering comma instead of point for decimal separator
With some keyboards (for example Swiftkey, see https://fuelio.userecho.com/en/communities/1/topics/50-please-add-numeric-keyboard-for-entering-fuel-data), it's not clear that we're supposed to use the dot (for non-US users).
It may actually have led to https://fuelio.userecho.com/en/communities/1/topics/147-no-decimal-fraction-edition-concerns
Even with the standard AOSP keyboard, the comma is shown.
Why not accept the comma and replace it internally by a dot (while still showing a comma as it already does)?

backup all messed up
Hi !
So at some point, I noticed that the last entry on my vehicle was an entry from a year ago, while I had put in gas data a week ago, and many more in the last year.
I checked my Google drive and saw that there were 2 Android folders with fuelio folders inside. One had even multiple vehicle-2 CSVs.
I checked the CSVs to see if one of them still had the data dat got lost. I found that one of the CSVs had an older version (10 versions back) with all the fueling data that wasnt showing up anymore. Just in case i downloaded that CSV version to have a backup.
Then I tried all kind of things trying to restore it without success, untill I found on one of the messages here that Fuelio cannot read any file created, saved or edited by the user.
So now I have an app where i have deleted all vehicle data, and i have downloaded backup files with correct logs and pictures etc.
Is there any way i can still import his data somehow to be back to normal?
Thanks for your time.

Wrong last calculation, not show data
Hi, i have problem with latest data after tank. It is still showing as first refuel
how to make that this will be calculated as other ones?

Add x axis coordinates on chart
when selecting a point on the chart, the app only shows the y axis coordinate. Please add the x axis point too
in the screenshot above, date is y/m/d, and it seems to be 79k km sometime in 2020 but it's not displayed

Average cost per kilometer (CSV and screenshot attached)
What is the calculation behind the R$ 0.44/km avg cost per km showed by Foulio in this screenshot?
I've read the previous post about this topic, but failed in reproduce that number showed by Fuelio.
I have also attached the csv file.
Thanks in advance.

Does positioning new petrol require mobile data connection
I regularly travel in regional areas of Australia where I have no mobile coverage, but GPS works fine. When trying to add a new fuel station, by selection on the map, I am unable to add it sometimes, and it appears to be when i have no mobile coverage? Is this correct? I should not need mobile coverage to add a new fuel station, as long as I have GPS coverage. It should just sync next time I come into a coverage area.

km/l always empty in CSV for latest fillup
In the CSV Fuelio creates the "km/l (optional) column is always empty for the last fillup.
All previous ones are filled in properly.
The app properly shows the last usage on the dashboard / in the logbook however the number is always "0" in the created CSV.

Edit distance clocked by auto start
Hi,
Is there a way to edit the distance recorded by the GPS? As it stands currently, it is over recording the distance vs what my trip counter has by 9KM.

Lock in fuel price when entering amount of fuel
Somewhat often, when I am logging a refill I will accidentally erase the current fuel price. If I begin to add the quantity after I'm fully fueled, but then erase the only number entered, the $/gal disappears. Would be very handy to have a little padlock icon or similar next to the field!

currency conversion difference between costs and fuel log
It looks like the calculation conversion is different/opposite for costs and mileage log.
For instance my main currency is CHF and I added the HRK with the exchange rate as: 0.14 (meaning 1HRK = 0.14CHF)
So if I add a cost of 150HRK for car wash it is correctly translated to 21CHF (done by 150*0.14)
However if now I do a fuel log of 700HRK I would get a price of 1071CHF (done by 150/0.14) which is wrong.
Conversely if I correct the exchange rate by adding HRK and putting 6.8 (meaning 1CHF = 7.8HRK)
I get the opposite problem (fuel is correct but car wash is wrong)
I'm not sure if this bug depends on a particular currency but I would assume it's just a wrog formula in Costs log or Fuel log)
