I wonder if there is a app
There is not
There is not, but you can add an icon link for the site to your home screen and turn on notifications. How successfully the notifications work will vary depending on your phone model, browser you use, and notification settings.
I'm pretty sure there used to be but for some reason doesn't exist anymore
Are you serious? I thought i was using an app. If I'm not this is a fake app. OMG 😱
