The great thing about fucking guys is that in most cases they want exactly what you want. You don't have to buy drinks, talk about your feelings, have a special connection, jump through hoops, convince them they aren't whores for doing what they want to do etc etc.
I would say less than 10% of guys on the dating apps are looking for anything more than sex.
All you have to do is be clear with what you want, state what your limits are and be smart enough to dodge the catfish (same as straight dating apps) and you will be fine.
This is pretty much everything, every word of it.
I think your experience will also be impacted by where you are. I live in a gigantic city, so my experience with apps hasn't been as bad as some. But largely I tend to agree that Grindr is a lot more problematic, and the quality of the guys - and the sex - I've gotten off of that (and the frequency come to think of it) is meh, and its riddled with fakes but they're pretty easy to spot. I have a lot more success with Scruff tbh, across the board.
But yeah clarity and directness is your friend. To the point
@Brodie888 made, my profiles make it abundantly clear that I'm only looking for sex when I have those apps open. And I am very direct about the fact that I am down to either suck or get fucked, but all I want is your cock, to get you off, and to make you cum. Open to reciprocation, but it's also unnecessary - my holes are what are on the apps, not my dick (and certainly not my heart). Most guys are pretty good about reaching out only to compatible matches in my experience.
And of course after shitting on Grindr, I also found one of my favorite fuck buds on it, and also one of my favorite suck buds, and they both live less than 10 mins from me. So... I guess it's not completely useless LOL.
