The lightning fees are low but most sellers sell at a premium.

Of course they do, that's the price of privacy. I've done hundreds of trades on Robosats and never paid above 4%, usually between 2-3%. I'd say that's a damn good deal for No-KYC. Bisq's average for me sits closer to 10% and Peach around 7% (though I wouldn't recommend Peach to begin with).

I don't see it on the playstore? 🤔
