One warning about free services: requests for money at any stage are a hard stop.
The variable nobody controls for with free services is the time of year.
The real differentiator across free services turned out to be whether the match volume held up past the first week.
If you are starting with free services, test it on a weekday evening, not a Sunday morning.
Two people can have opposite experiences of free services purely because of the time of year.
Half the arguments about free services would end if people mentioned how many people locally are already on it up front.
Not the last word on how to cancel my subscription on the eharmony site by any means.
I rotate between a couple of these and Datewander (datewander.site), mostly because neither charges to open a chat.
Worth searching the forum for Rendate as well, there are a few longer write-ups.
