Genuine question about over 50 dating sites from someone who's tried the obvious routes. People dating later in life feel this hardest on host sites, where the platform keeps deleted profiles in search for weeks, and it skews every review you will read. The real-life host angle is worse, because the platform boosts newer accounts over established ones, and the share of verified profiles suffers for it.
Every time host sites comes up, how honest the pricing page is is the number worth watching, not the size of the database. Real-life is the clearest case of it — the depth of the profile fields collapses as soon as the platform boosts newer accounts over established ones.
Host sites is where I'd start, since the depth of the profile fields matters more than the badge on the download page, having tried a handful of these. Treat over 50 dating sites as a filtering problem and it follows that what decides it is the reply rate, not the app store rating. If you have been through the real-life host version of this, I'd rather hear the unglamorous account.
