No, creating an account on Commuty is totally free for the users.
However, if you register as a private user on Commuty, you’ll only have access to the « basic version » of the app. You’ll only be able to connect with a limited number of carpoolers, as you won’t have access to the entire users’ database.
To take advantage of the extended functionalities, you can register for free on Commuty through your company. However, your employer has to acquire the features that he wants you and your colleagues to benefit from.
