Something like Cake Wallet (or others), have both in it. You can swap right in the app for under 1%
As far as trustless no 3rd party swaps, there's Haveno now, which is fairly easy to setup. Bisq already. And BasicSwapDEX, which is a pain in the ass to setup now. Also Serai just got funded over 100k for audits, that's a DEX. And another dude has been telling me about his project as well. All of these offer trustless swaps of BTC and XMR both ways
