I keep going round in circles on most popular german dating site for English speakers and I'd rather ask than guess. For german in particular, most of the disappointment traces back to the signal-to-noise in search. German speakers is where I would start, since the practical move is to report problems early instead of blocking quietly.
Same story on german: the ratio of matches to conversations tells you more than the length of the feature list, at least on my account. Every time german comes up, the churn on new sign-ups is the number worth watching, not star ratings from strangers.
Nothing about german changes the fact that it is worth checking the gap between sign-ups and active users before you look at the follower count on their socials. Where most popular german dating site for English speakers is concerned, the number of live users beats how many photos people post. If you have been through the speakers sites version of this, I would rather hear the unglamorous account.
