In this day and age, it’s increasingly difficult NOT to become at least a little interested in the small (or maybe not so small) charges that you incur on a regular basis. With gas prices soaring, tracking your vehicles fuel economy has become a regular practice for many consumers, myself included. It can be hard, though, to maintain a database of all your mileage information and aggregate this data in a pleasing and useful way.

Update by Jaroslav (11/2/10):

In light of the new version of the app (2.3.0) as well as aCar's first birthday that is coming up on November 5th, we thought we'd update the review with a roundup of the new features and throw a giveaway of 20x aCar Pro licenses. Scroll towards the bottom for more info.

Update: This contest is now over. We have selected the winners - see if you are one of them towards the bottom of the page.

What's new in v2.3:

  • There are now a few more options available right from the app's main page, namely:
    • Expense Records - a place where you can jot down the expenses of your vehicle for future reference
    • Trip Records - like Expense Records, only for trips
    • FAQ - really helpful if you're just getting started with the app
  • Bug fixes aplenty
  • "UI Improvements" - I haven't really noticed any, but Armond, the developer, says they're there

Wait, let me back that up. Rewind. Enhance.

It can be hard, though, to maintain a database of all of your mileage information and aggregate this data in a pleasing and useful way if you've never heard of aCar.

I discovered this little gem about 6 months ago and, because of its usefulness and ease, I have actually begun to enjoy filling up my tank (though my wallet may beg to differ). The basic idea of this app is that, whenever you fill up your tank, you input:

  • How much gas you put in
  • What your odometer is at and
  • The price of the gas you put in

aCar also has some handy accommodations for the off-chance occurrence that you forgot to tell it about your last fill-up.

Now that we know what it is, let's talk a little bit about how to use it. I will say that, despite how much I love this application, it can be a bit daunting the first time you open it:


It does a lot of things, and you can tell that immediately. The first step is to tap on the "+ Vehicle" button and add all the information about your car (you can keep track of multiple vehicles). After you've added a car to your inventory, it's time to get some gas. When you tap the "+ Fillup Rec" button, you are presented with four text boxes and some options:


Input your total mileage and how much you put in the tank. If/when you tell it the cost per gallon, it will auto populate the total cost. Nifty! You can then tell it what grade of gasoline you used, how you paid for it, and whether or not you missed a fill-up. Lather, rinse, repeat every time you fill up. After the second fill-up, the "home screen" will tell you your mileage and show some nice charts about your fuel consumption and spending.

In addition to that, the "Charts" icon will whisk you away into a wonderland of graphs and charts to show you how much that car of yours affects your wallet. In a similar vein to the charts, the "Statistics" section will tell you everything you could possibly want to know about your car's fuel economy:

In addition to the amazing job aCar does with your gas mileage, you can also use it to keep track of your scheduled maintenance. You can input any work you have done, which is useful to provide a more complete pictures of the running cost of your vehicle, as well as set up reminders for oil changes, tire rotation, and all the other things I can't remember to do until it's too late.

After using the app for a while, it becomes second nature to open the app alongside your wallet when getting work done on your car, and you can get a really great picture of how often it's happening and how much it is costing you.

You can also donate to the developer and gain the ability to backup and restore all your car's information at any time. This is especially handy if you change phones often, which I do.

Overall, I would have to give this app no less than a 9 out of 10. It knows its functions, and it does them extremely well. You can get a very clear picture of how much your car is costing you. You can also use it to let you know when your car needs its scheduled maintenance so it doesn't end up costing you more in repairs.

The only downside that I really see in aCar is the user interface which, in all actuality, isn't really that bad. While nothing is there that shouldn't be there, it can sometimes be difficult to figure out what to do first. After you get used to it, though, it becomes second nature to use this app at every opportunity.

I know that I, personally, will never be without this app. It’s a must have, in my opinion.
