I've successfully installed WWWhisper in my Heroku app. I can log in and see the site. But I can't find any documentation on where adding other e-mails and permissions would be. Like the admin page they display in pictures.
I found it. According to https://github.com/wrr/wwwhisper/blob/master/wwwhisper_service/settings.py#L12 it's at /wwwhisper/admin/
