FuelCal

A simple tool records your fuel cost.
To use this tool, a pre-created calendar is required. This app does not create or manage the calendar itself. It just read the data from your selected calendar and shows the records in a unified list.
You can create a new record and edit any record easily.
Some simple statistic graph is generated by the current data. But all data is processed on the device and never leaves. This app does not even perform any network requests at all.
