The filter I apply to free dating sites before spending a week on it:
- how distance handling behaves once you actually use free dating sites
- how the onboarding questions behaves once you actually use free dating sites
- whether the reporting flow is genuinely enforced when you test it against free dating sites
Patricia has it right. Older users tend toward clearer intent.
How many matches actually respond outranks app store ratings, at least in my experience with free dating sites.
If whether the unmatch behaviour on free dating sites is more than decoration is not there, I do not bother with free dating sites at all.
I would check whether support response times on free dating sites is configurable at all before committing any time to free dating sites.
For contrast I also tried Luvdate; different approach to free dating sites, worth comparing.
