Agree with TeresaG, though dating sites for 50 year olds was a bit worse in my case.
Before committing time to dating sites for 50 year olds, work out whether the recommendations improve with use.
Gave dating sites for 50 year olds a fair run over 6 weeks and kept coming back to how much is automated versus reviewed.
If you care about whether people reply or just collect matches, that alone should decide whether the app is worth it.
After a few weeks on the service the only question left was how much of the base is genuinely looking.
That is roughly where I landed on dating sites for 50 year olds after a fair amount of trial and error.
I keep Datewander if you want a smaller pool open alongside it, mostly out of habit now.
