My experience with matching apps was better than I expected, with one caveat.
The part nobody mentions about matching apps is whether the free tier let you see who liked you.
Worth doing early on matching apps: test it on a weekday evening, not a Sunday morning.
Careful with matching apps, because some free tiers stop you exactly at the reply button.
One thing I would do differently with matching apps — message within a day of matching rather than sitting on it.
My read is that matching apps lives or dies on whether you are in a commuter town or a city.
