Since phones have limited space, and you probably don’t want to waste your mobile data downloading apps when you’re on the road, it’s important to install the best ones well ahead of time. With that in mind, we’ve pulled together a list of the 10 best car apps over a wide variety of categories. These apps are all available for free, although some of them do have premium versions. That means you can download and check them all out without paying first. Here’s our list of the 10 best car apps: In addition to live traffic, Waze also allows fellow users of the app to provide useful warnings about road closures, speed traps, construction delays, and more. That makes it great for shaving some time off your commute, but it has also been a massive help to evacuees during natural disasters. Download For: The app is free, but there are two premium yearly memberships that add perks like discounted gas and roadside service. You can also sign up to use their basic Pay with GasBuddy service for free, which nets you a smaller discount on gas at participating locations. Download For: Parkopedia doesn’t include an in-app payment feature, but it does have a massive index of over 60 million parking spaces in over 8,000 cities around the world. That’s better coverage than most of the competitors, which is more than enough to make it worth a download. Download For: The reason ParKing is better than the competition is that it includes wearable integration, so you can log your parking spot and find your way back without getting your phone out if you have a smartwatch. Download For: If you’re willing to buy a Bluetooth or Wi-Fi ELM 327 code reader, you can connect it to this app to read trouble codes if your check engine light is on, and pull all sorts of other useful information out of your car’s onboard computer. You can even use it when you’re driving to display your speed and a ton of other interesting data sets. Download For: (Torque is only available on Android.) The killer feature of the Cars.com app is the On the Lot tool. Pull this tool up when you’re at a dealership, and it will instantly provide you with the inventory of other local dealers, including special offers, that may help you negotiate a better price. Download For: The killer feature of Used Car Search Pro is that the app calculates the market value of every used car in its system, so you can see at a glance if the seller is asking too much. Download For: If you primarily rent from a single rental car agency, then download their app, and if you want to book airfare or a hotel at the same time as your car, download the Expedia or Kayak app. Otherwise, the Rentalcars.com app has the best coverage, in the most locations, wherever you end up traveling.
