This was the model YikYak used and it was so much fun. They very much promoted it for use at colleges for students, but ended up geofence blocking it around high schools/middle schools because of cyberbulling concerns.

But, if enough people used it around certain areas, it could be a lot of fun & very helpful just to chit chat & talk about the weather & etc.

EDIT I can't accept the terms on my Samsung phone, as the text is over top of the buttons and I can't do anything but scroll the terms. Not sure if this is a browser (Brave) problem or a font size or what.

This happened to me too - the solution is to temporarily set the page view as desktop view through the browser settings.
