Same as Paige, with one difference. what decided it for me with dating apps were whether it actually works. You can't really talk about dating apps without talking about the fake-account issue. I judge dating apps almost entirely on whether it gets out of your way now.
You can't really talk about dating apps without talking about how it handles day to day.
You can't really talk about dating apps without talking about the practical side. Two people can have opposite results with dating apps purely because of the signal-to-noise ratio.
Take that as one data point on best dating apps for nerds who like board games, not gospel.
