Modern users are quite demanding, aren’t they? These days they not only expect you to create a great product but also develop an exceptional way to interact with it. For example, for a modern TV it likely won’t be enough to have a rich picture and crystal-clear sound. Voice control and WHAT operating system are some things users would really like to see.
It’s not that different for electric vehicles, right? From Tesla and BMW to Volvo and Toyota – apart from designing a neat car itself, automotive companies accompany them with companion mobile apps that take customer experience to a whole new level. And we are not talking only about cars here, as it’s absolutely relevant for electric bicycles and scooters, too.
But how do you make a user-friendly automotive app and ensure flawless data exchange between the app and the vehicle? We’ll answer these and other questions in this article. Also, we’ll share our tips on how you can enhance the main features of such an application and implement them easier and faster.
Let's figure it out!
As we’ve said earlier, this guide covers companion app development for both electric cars and scooter/e-bikes. However, since these 2 types of mobile apps differ in their functionality, in this section we’ll focus on features you can use to create a car companion app. Further in the article, we’ll discuss electric scooters, too.
This can be considered the main screen in the automotive app, where all information about the electric car should be displayed, from the model to the air temperature.
The main thing here is to correctly divide the information into important (one that can be seen on the screen without taking any action) and secondary (for which you can make an extra swipe).

For example, you can add the following information to the home screen:
This is also the screen where we recommend placing key control features like (un)locking the car and starting the engine. That’s something drivers use often so bringing it up-front should noticeably improve the user experience for them.
Add interactive elements, such as images of a car that you can interact with to adjust the temperature settings for a specific seat or lock doors.
This is one of the most important functions in the automotive application, which will help the owner of an electric car to monitor and adjust individual values for the charge of their vehicle.
How to Make an EV Charging Station App
On this screen, it would be cool to add a chart that will clearly show the amount of energy received, how much money is spent and where the car is charging.
DeftPower is a companion app for EVs developed by Stormotion
If the car is charging, the app should display indicators such as: the amount of charge received (in percent and kilometers) and the time left to fully charge. In this case, a good solution would be to add charge settings for the user, where they can set up a percentage limit to charge the car or until what time to charge it. You can also add a nice feature showing an amount of saved fuel — another reminder of the advantage of using an electric car.
Add the ability to enter the cost of electricity in mobile apps depending on the location of the owner. So the indicators of the funds spent will be even more accurate.
We think you’ll agree that climate control is a convenient thing. Before getting into the car, the user can remotely adjust the temperature inside the cabin.
Climate control settings can be placed on the main screen of the application, along with all the important information about the electric car (image by 7ahang)
But besides the benefits in terms of comfort, climate control can help the battery last longer. This function is called “preconditioning”. It allows you to preheat or cool the battery before using it to the optimum operating temperature. Thus, the battery of the electric car will last longer.
You can add the ability to pre-set the start time of the climate control to the app.
Ride statistics are important for electric vehicle app developers to analyze user behaviors and preferences. By analyzing this information, you can see which features are the most popular and how you can improve the app experience to better meet user needs. Furthermore, ride statistics can provide insights into user driving patterns and help identify potential safety issues or opportunities for improvement.
For example, if a user is consistently driving beyond the battery range of their electric vehicle, the app could provide alerts or suggest an upgrade to a larger battery capacity.
Smart locks can be integrated with automotive apps to provide an extra layer of security and convenience. Once connected, the app can be used to remotely lock and unlock the car.
In the application, you can clearly show which door is open or closed, for example, as in this picture (image by Dmitry Litvinenko)
In order to implement the function of locking/unlocking the doors in the application, the technology of intelligent locks is used. Smart lock works via Bluetooth or Wi-Fi and allows you to operate the doors without using a regular key.
Since the automotive app monitors the battery level and everything else, your development team can add special warning messages if the battery indicators are bad. You can also enable users to monitor the various indicators of the machine, which can be read thanks to special sensors.
Many automotive apps provide an appointment booking feature that you can use to schedule an appointment at an authorized service center. You can add a reminder after a certain time that it’s time to call the service center.
Companies like Tesla offer an online service appointment feature that allows you to easily schedule an appointment to have your vehicle serviced.
A companion app user should always have easy access to customer service representatives. You can implement this in several ways so that the driver can choose the most convenient for them:
When it comes to onboarding, there are several digital solutions on how to implement it:
Electric scooters are mainly connected to a smartphone using the built-in Bluetooth Low Energy (BLE) module. With this feature, the user can monitor battery status, ride speed, adjust brakes, and more directly in the app.
We have expertise working with BLE. You can read more about this technology here:
Bluetooth Low Energy FAQ
This stage of interaction with the application should be clear to the user. Therefore, in addition to the Bluetooth connection button itself, you can add a small guide on how to do it correctly.
The dashboard (thanks to the Bluetooth Low Energy connection) provides real-time data such as speed and distance, maximum speed limit detection, and battery status. With this information, the user can maintain control of the scooter and maximize the power reserve.

You can add the following metrics to this screen:
One of the main features that should be displayed in the electric vehicle companion application. It will be convenient for the user to monitor the battery charge and adjust the settings to suit their needs.
All data about the state of the battery and charge are also transmitted using the BLE connection which we described above.
The companion app should provide users with useful maintenance tips, such as the correct tire pressure.
To make the feature user-friendly, a small guide can be added to the application on how to choose the correct tire pressure depending on the weather, the average speed of the trip, and the weight of the driver.
However, for safety reasons, it would be beneficial to also include the following reminders or small guide for e-scooter riders:
Check and clean the brakes regularly.
Check the battery level and charge time regularly to keep it in good condition.
Check the headlights and reflectors.
Check for loose bolts and screws.
Always wear a helmet and other protective gear while riding.
Familiarize yourself with local laws and regulations when riding an e-scooter.
Electric scooters always have built-in safety features, mainly locking mechanisms and anti-theft alarms. However, these devices usually aren’t designed to track the location of the scooter. That’s why some owners install GPS trackers themselves or use the Air Tag.
Since it’s a common thing, your customers will likely expect the app to be able to see the GPS data. It will be much easier to integrate if your scooters or bikes already come with built-in GPS sensors. Yet, even if they don’t have one and you leave it for your customers whether to buy and install third-party GPS trackers, it’s still possible to leave a place in the app where your customers would be able to connect them.
Important: In order to track the location of the scooter in the application, you can add one more additional feature — a security password (as an additional security measure). When the owner of the scooter logs into the application and enters the password, access to the location of the scooter will be granted.
This feature, in addition to being convenient for the user during the start or end of the trip, can also be an additional protective measure of the electric scooter.
Thanks to the electronic lock that can be controlled, the owner of the electric scooter can lock the vehicle right on their mobile device. And in case of attempted theft, the brakes will automatically lock and the siren will turn on.
Important: You can add a special alert notification that will work if the locked electric scooter starts to move in the app. However, that feature will probably require a cellular connection as BLE just won’t cover the needed range.
Cruise control can be useful for owners of electric scooters for long trips on the bike path. The main feature of this mode is that the driver of the electric scooter does not need to constantly hold the throttle, just the handlebars. And the vehicle will drive and maintain the set speed.
The owner of the electric scooter can activate the cruise control from the application and turn it on even during the trip. For example, in Xiaomi Mi Electric Scooter, you can enable this feature by holding the throttle for a few seconds. And turn it off by simply pressing the brake. Take a look at the example below:
Vehicle statistics and trip history allow the user to track various characteristics and analyze them. You can add the following metrics to this screen:
Also, tracking these indicators can help the owner of the scooter to contact the service center in time and avoid unpleasant situations during trips.
The support function in the Companion App for electric scooters is no different from the support for electric cars, which we talked about above.
You can choose several convenient support options or use them all at once. And in the section on Tech Stack we’ll tell you about how to develop this feature quickly and correctly. Read on!
Communication between the car and the mobile app typically takes place over a wireless connection, such as Bluetooth or a cellular network. Bluetooth is a short-range wireless technology that allows devices to communicate with each other over a range of about 30 feet. This technology is typically used for communication between the car and the app when the user is in close proximity to the vehicle, such as when they are in the car or nearby.
On the other hand, cellular networks use cellular data or an Internet connection to communicate with the car, when the user is not close to the car. This type of communication is useful when the user wants to access the car’s information or control certain features remotely, such as starting the engine or unlocking the doors.
This allows the user to remotely control various aspects of the car, such as the doors, windows, and climate control. This means users can start their car, lock or unlock the doors, turn on the AC, control the radio, and other features directly from their phone. Additionally, the app can receive real-time data from the car, such as the current speed, location, and battery status. And drivers can monitor vital statistics, which gives them more control and peace of mind.
Other features that may be available are:
Software updates for the car or e-scooter are typically carried out through the companion app. The process of updating the software can vary depending on the manufacturer, but in general, the process involves several steps:
1️⃣ Checking for updates
The user can check for available updates. This can usually be done by going to the settings or software update section within the app. The app will then check for any available updates and display a notification if one is available.
2️⃣ Downloading the update
Once the user has confirmed they want to update, the app will begin downloading the update. The amount of time this step takes will depend on the size of the update and the speed of the user's internet connection.
3️⃣ Installing the update
After the update has been downloaded, the app will begin installing it on the car or scooter. This step may take several minutes to complete, depending on the complexity of the update.
4️⃣ Progress updates
During the download and installation process, the app will provide progress updates to the user, letting them know how the process is going.
5️⃣ Finalizing the update
Once the update has been installed, the app will finalize the process and apply any necessary changes. This may involve restarting the car or scooter.
6️⃣ New features and improvements
After the software update has been completed, the user can access the new features and improvements that have been added in the update.
Some of the new features and improvements that can be included in a software update include:
Overall, software updates are important to keep the vehicles running smoothly and ensure that it has the latest features and capabilities. By regularly checking for and installing updates, the user can ensure that their vehicle is always up-to-date and performing at its best.
Some companion apps are also able to intelligently build routes based on the state of charge of the car and the number of charging stations ahead. This feature can help the user to plan their trips more effectively and avoid running out of charge. Some additional features that may be included in this type of app include:
By using these features, the user can plan their trips more effectively, and ensure that the electric car always has enough battery power to complete a journey. This can help to make automotive ownership more convenient, and reduce the stress of worrying about running out of charge on the road.
How to Make an EV Rental App
In this section, we have compiled various technical tools to help you and your team in the automotive app development process.
Norsk Guardian is a companion application developed by the Stormotion team for Norsk Lithium, a company that manufactures lithium-ion batteries for recreation on the water (boats, kayaks, etc.).
Thanks to the Bluetooth Low Energy module installed in each battery, the application can collect and evaluate data on the state of the battery. The main purpose of the application is to prevent any dangerous situations due to battery problems. The mobile app allows users to control the battery temperature, voltage, charge current, and other important parameters. If these values deviate from the standard level, a warning is sent to the user.

To successfully develop this application, our team had to create a system that could quickly transfer data between the battery and the mobile phone. In addition, we had to configure the system so that it understands when parameters indicate potential problems and alerts the user before a problem occurs.
Despite the difficulties in development, we managed to establish an ideal communication system between the battery and the application. And all users of Norsk products don't have to worry about potential problems with batteries, because if something goes wrong, the application will notify them.
DeftPower is a standout example in the field of automotive app development. It's a white-label app for drivers that simplifies the entire charging process.
The app connects to drivers' cars and provides a smart navigation system to find the nearest charging station. It also allows users to monitor their car's battery charge level and make payments through the app.
