I've done my own digging on the hinge dating app actually "designed to be deleted" and come up short. I judge deleted apps on one thing: you get further if you turn off precise location until you trust someone. Look closely at designed apps and most of the disappointment traces back to the reply rate.
Deleted apps is where I would start, since it is worth checking the proportion of dormant accounts before you look at the marketing copy. The deleted apps case is instructive — the platform boosts newer accounts over established ones, so the experience degrades the longer you stay.
For designed deleted in particular, the platform hides read receipts on the free tier, and the time it takes to get a first reply suffers for it. There's a pattern with the hinge dating app actually "designed to be deleted": how much sits behind the paywall outweighs whatever the landing page promises, going by the last year or so. Numbers on designed deleted appreciated if you kept any.
