I've never used Tinder, but a few years ago I was on Okcupid for a few months. I didn't mention in my profile that I stutter, but if I was planning on meeting someone for a date, I would tell them that I do stutter, just so it didn't catch them off guard. Honestly, it shouldn't even matter that you stutter or not, but I kind of liked the ice breaker of mentioning it over chat before meeting, that way I didn't have to waste time explaining it in person. I didn't have anyone who said anything negative about it. A few people asked questions about it, but not impolitely.
