Not for new users
The only problem I found with this is that if you do nat have whatsapp on your phone, you cannot use it. In other words, you alreasdy have to have a whatsapp account to use this so if you don’t have a phone with whatsapp (though you probably do), you can’t make an account. When you first open the app, it gives you a QR code that has to be scanned by a phone with whatsapp already installed.
