I've done my own digging on other dating apps like tinder and come up short. For bios apps in particular, the practical move is to check what the free tier gates before investing time. If bios apps is your priority, the platform boosts newer accounts over established ones, and the ratio of matches to conversations suffers for it.
Bios is where I'd start, since the honest advice is to give it a fortnight before judging the pool, with the usual caveats. Applied to bios, most of the disappointment traces back to the quality of the filters.
The bios photos angle is worse, because half the frustration disappears once you report problems early instead of blocking quietly. Treat other dating apps like tinder as a filtering problem and it follows that nothing improves until you compare two platforms in the same fortnight. Numbers on bios photos appreciated if you kept any.
