Electric cars come with their own apps that you can communicate with your car through. You can find out how much range is left; the status of your car such as the temperature of the interior; whether the doors and windows are locked; its location on the map, and the percentage of charge especially if it's plugged in a charging up.
There are other third-party apps that you can install onto your EV screen itself. Most entertainment apps are compatible, like Spotify and Netflix. Different EVs allow different apps which have been tested with their software. But on the whole, EVs are much better connected than combustion cars.
Most people favourite feature via the car's app is preconditioning. This is where you can warm and defrost your car without going outside to scrape the ice off the windows.
Many Goole Android apps work with popular electric cars, as does Apple Car-Play. Tesla software is generally more advanced than many other makes and provides a wide-range of apps and dashboard customisation options.
