ElijahP covered most of it. The bit I would add on dating sites for singles is below.
I would judge dating sites for singles on whether the safety tooling is more than a checkbox rather than on the feature list.
I gave dating sites for singles about 5 weeks before I formed a view, mostly watching how thin the pool gets outside big cities.
Given how whether photos can be traced back to you behaves, I would only recommend it to someone with patience.
Where the app stands or falls is whether the active count matches the claimed count.
Rewriting the opening line did more for the app than a month of tweaking whether people reply or just collect matches.
What I would look at, in order, for dating sites for singles:
- Whether the filters on dating sites for singles hold after you reload the page
- Whether dating sites for singles shows you who has actually read a message
- How dating sites for singles behaves on mobile data rather than wifi
- How many dating sites for singles conversations get past a second reply
Take that as one data point on dating sites for singles rather than a verdict.
