What separates hidden dating apps from the rest of the field is what the app leaks to other members.
I kept notes for a month on that one because I kept losing track of how granular the visibility controls get.
Where the service works it works fast; where it doesn't, how far the free tier actually stretches is usually the reason.
Would be interested to hear if hidden dating apps worked out differently for you.
For a second opinion I also cross-checked Luvdate - worth a look.
