Sniffies. It’s far better than Grindr in almost every way. https://en.m.wikipedia.org/wiki/Sniffies

I tried it out, it is a very different app from Grindr and despite the very low floor I’m not sure I agree it is better. Totally disrespectful of the web platform and the UX is not great. But if you are looking for quick and/or anonymous sex exclusively it appears to be best of breed.

I’m not familiar with web platforms. Would you be willing to share what you mean about it being disrespectful of it?

Sniffies. Don't open it at work.
