Nobody needs to have the app to receive your profile! If the other person does not have our app, your profile will automatically open in the web browser of their choice.
By the way: Your profile will of course also work if you delete the app after setting it up!
Nevertheless, we recommend the app to manage your contacts and to be able to make quick changes to your profile. Nowhere else do you have such a good overview of your contacts, with filter functions and the function to create new contacts directly!
