After your phone, the second-most used device in your life outside the home is your car. These apps and websites will help you take care of it and save some money on repairs and unnecessary expenses.

These myriad tools cover a range of automobile-related issues.

There are calculators to figure out how much you should pay, loans you can get, and the car's lifetime costs. A couple of apps help you track expenses and figure out true mileage, along with getting you the cheapest gas prices. And there are a few experts at hand to help you fix basic issues without needing to go to a mechanic.

1. Drivvo (Android, iOS): Track Expenses, Mileage, Service Reminders, and More

Drivvo is one of the best all-in-one car management apps you'll come across, and it's free. With it, you can track expenses, calculate mileage, get average gas station prices, and even set reminders for car services.

The whole app is manual, so you will need to enter the details yourself. But it's easy to do that while you're waiting for the tank to fill up. It's a basic set of inputs, like why type of fuel you're using, what the odometer says, the price, and the gas station you're currently at (which can be put with GPS).

Drivvo will track every input for income, service, route, expense, and refueling, creating a dashboard that shows all your car's vital statistics. It even turns them into charts for reports. And you can set reminders for expenses or services, along with notes.

The Pro version has a few advanced features like adding unlimited incomes, exporting the data to spreadsheets, and so on. But most people don't need them, and you'll be happy with the basic Drivvo app for your personal use.

2. GasBuddy (Web, Android, iOS): Find Cheapest Gas Stations Nearby

Gas prices vary at each station. Why pay more for fuel when you can quickly check GasBuddy to find the cheapest pump nearby? Just download the app, grant it access to track your current location, and you'll see stations on a map or a list.

By default, it lists stations based on the price of regular gas, but you can change that to mid-range, premier, diesel, or unleaded. You can also filter stations by amenities you are interested in, such as restrooms, pay-at-pump, air pumps, ATM machines, and convenience stores. And you can see what other people have said about the station.

GasBuddy has a few other built-in tools. For example, it keeps track of your refuels to tell you how efficient your mileage is. And the website has data-based tools, like Fuel Insights to see rise or fall in retail fuel prices. It's one of the best thrifty apps to save money on car expenses.

Of course, GasBuddy is only for the USA, but there are similar apps for other countries. For example, you can check Gaspy for Australia and New Zealand, or INSADCO's Cheap Refuel for major European countries.

5. Automotive Forums (Web): Ask Any Question You Have
