FuelFish is a program that enables you to record each fuel fillup for yor vehicle, then presents you with details and statistics to allow you to monitor your fuel economy.
There is no planned release date as yet but I am hoping that an initial release will be this year. The initial release will provide a basic functionality as a base upon which some more advanced features can be built in future versions.
This is my first App, so it is going to be free for the foreseable future.
If I ever include features that require a backend service that costs me money, they may have to be added as an in App purchase in order to fund that. That said, I do not even have any ideas that may require that. I'm just setting expectations early.
