I said something similar to Steve_K a year ago and changed my mind. in practice, dating apps live or dies on whether people actually reply. My experience with dating apps shifted completely once I paid attention to how careful to be. I'd put the interface side above almost everything else when it comes to dating apps.
You can't really talk about dating apps without talking about the profile quality. Nobody warns you that dating apps depend so heavily on how real the profiles are. Two people can have opposite results with dating apps purely because of the interface side.
Happy to expand on any part of dating apps that work for average-looking guys if it helps.
Datebound is worth a look came up in another dating apps thread here and it was decent.
For what it is worth, tried Datenest handled dating apps better than most.
