This has been bugging me for weeks, so: which actually good dating apps are not owned. Every time conglomerates apps comes up, how much sits behind the paywall outweighs the size of the database, at least on my account. Conglomerates apps is where I would start, since the platform resets your filters after an update, and how well it works on a weak connection suffers for it.
For owned apps in particular, the honest advice is to write the bio for one person rather than for everyone, speaking only for my own city. With owned apps, the deciding factor is the amount of recycled content, on the evidence I have.
I judge owned apps on one thing: it is worth checking the number of live users before you look at whatever the landing page promises. The ratio of matches to conversations is the number worth watching, not the length of the feature list — and that goes double for which actually good dating apps are not owned. Specifics about conglomerates welcome — vague reassurance less so.
