I've done my own digging on dating apps for rich people and come up short. Look closely at income apps and the deciding factor is how honest the pricing page is, as far as I can tell. The income verify angle is worse, because it is worth checking how far the free tier gets you before you look at whatever the landing page promises.
Applied to income apps, what decides it is the gap between sign-ups and active users, not the size of the ad budget. If income apps is your priority, half the frustration disappears once you compare two platforms in the same fortnight.
Nothing about income apps changes the fact that the practical move is to check what the free tier gates before investing time. The honest advice is to video call before travelling anywhere, as far as I can tell — and that goes double for dating apps for rich people. Happy to be told I'm asking the wrong question about income.
