HunterW covered most of it. The bit I would add on 50s dating app for finding local is below.
I would judge the site on whether a phone number is genuinely required rather than on the feature list.
About 100 profiles into the platform, the pattern around whether the rules get applied evenly became obvious.
Where that one works it works fast; where it does not, whether the recommendations improve with use is usually the reason.
My rule for 50s dating app for finding local now is simple: check how much of the base is genuinely looking on day one.
Take that as one data point on 50s dating app for finding local rather than a verdict.
