Cake Wallet is also available on iOS, so yes I'd still recommend that. Though I also recommend against using an iPhone.

The 'self-custody' option of WoS is not really self custodial (see https://stacker.news/items/1020261 for further information)

So yeah, Cake Wallet + Monero offers low fees (about 1 cent TX fee regardless of how much money you send), fast tx (you see the money in a few seconds, and thanks to no RBF it's safe to accept smaller amounts without further confirmations), good privacy without any technical knowledge and it's fully open source and self-custodial.

There is no equivalent for BTC, that offers the same features.
