I just got into android development. But to learn the ropes I've been working on an app to keep track of miles per gallon that your car gets. So before I pay the fee to become an android developer I wanted to see how many people here would buy this application for $0.99.
It will have an interface to enter how many miles you've driven (since last fillup), how many gallons your car took, what the price per gallon is. It will display your average mpg, and the average price you pay per mile driven. It will also allow you to enter the number of gallons that your tank holds, and estimate how many miles you will be able to drive before running out of gas (to be safe I will use 3 standard deviations below the average).
Does this sound like something you all would be interested in? If not is there some feature I could add that would sell you on it?

There are some other apps on the market, but they don't calculate anywhere near good enough for me so I ended up using a Google Doc spreadsheet with a Form configured which I connect to the Form from my phone's browser to input the price per gallon, total cost, and trip miles. The first two are pre-configured selection boxes, while the only manual typed entry is for the trip miles. BUT, I have to have digital cellular coverage for it to work.
Anyway, I would suggest that you ensure your application automatically adds the 9/10 of a penny to price per gallon or cost history will be effected. That's another reason the apps in the market are not loaded on my phone.
Question; why would you need to input 'how many gallons your car took' if you have the price per gallon and the total price?
Here is the math calculation I use to calculate the gallons of fuel from price per gallon and total cost which I input on my Google Docs Spreadsheet Form.
Example:
I filled up at $2.39 and 9/10 per gallon with a total cost of $19.00 out the door.
The formula is;
$19.00 divided by ($2.39+.009) equals 7.92gal
19.00/(2.39+.009)=7.9199666527719883284701959149646
I use a program called Mileage by Evan Charlton. It works perfectly for me, it gives the option to enter fill-ups by unit price/total volume, total cost/total volume or total cost/unit price (along with the odometer) so you can choose which ever is easiest for you. You can set what units you want to use, date format and currency so it covers US Imperial, UK Imperial and Metric. It also collects location data. With all this info I can see at a glance when my vehicle is over or under performing. It shows all possible statistics from the given data and also supplies charts. The data can be imported/exported by SQLite DB, SQL or CSV. It also allows you to add service intervals by time and mileage so you are warned when a service is due. Best of all it's free!
I used to use a program on Blackberry called "TrackIt: Vehicle Edition" that was $25. Total waste of money and looked like crap. A spreadsheet is the way to go!
What I keep hearing folks ask for a is an application that provides the ability to track business, medical, volunteer & personal miles so that it can be imported into an excel spreadsheet and filtered by category for expense & tax reporting purposes.
This could easily be accomplished by creating a program that would be able to email a csv file.
A couple of suggestions.
You should be able to have multiple cars, it should remember the last ending mileage as your default starting mileage. It should also allow you to enter either the ending mileage or the miles driven.
Maintenance and gas would be nice, but there are apps that do that well already.
Kevin is right, we need a nice priced application for keeping record of miles for tax information, I need one and as a tax preparer I can tell you is hard for people to keep track on them on paper if that is on the phone man that will be a lot easy for them to keep track of if I have about 600 customers that need it and if you make it I will ask them to but it.
Let me know we can email each other and I can get you some needs for the application I found 1 but is about 20 dollars so at that price will not many people buy it.
