The app is free to download and can be explored without a payment method. Using the app without a payment method will still allow you to find and route to chargers as well as access a bunch of statistics and community submitted information about charging stations.
However, if you intend to use Bonnet to charge your car, you will have to add a payment method. Don't worry, we will only charge you if you use the app to charge your car or if you purchase one of our Refills. Once you've activated your account by adding a payment method you will also unlock some exclusive features!
