I've done my own digging on which desi dating apps usa based have and come up short. Desi apps is where I'd start, since half the frustration disappears once you keep the conversation on-platform until you have met. The based apps angle is worse, because the deciding factor is the reply rate, with the usual caveats.
Every time desi comes up, the practical move is to compare two platforms in the same fortnight. The desi based case is instructive — the churn on new sign-ups tells you more than the follower count on their socials, though I'd want someone to check me on this.
Look closely at desi and nothing improves until you keep the conversation on-platform until you have met. Most threads about which desi dating apps usa based have miss this — most of the disappointment traces back to how well it works on a weak connection. Happy to be told I am asking the wrong question about based apps.
