iOS wallets w/ NFC support? Experience using NFC signing devices on Android?

Hey SN - curious to hear what people's experience is using any of the recent signing devices relying on NFC has been like. Coinkite has been shipping products with NFC built in for most of this year (Tap Signer, Cold Card mk4) and the new Block hardware wallet is NFC based as well, I believe
As someone with an iPhone (like many Americans), I've been unable to take advantage of the NFC features as I'm not aware of any iOS wallets with NFC support at present. I know that Nunchuk on Android has had NFC support since Coinkite started shipping devices with NFC coils.
It seems like NFC has advantages in usability over QR-based data transaction signing/broadcasting, and I'm looking forward to this option being more widely supported/available in the future.

I’ve been using nunchuk on iOS to play with SatsCards, TapSigners, and the nfc-enabled coldcard (mk4).
I have a couple wallets in nunchuk to play with the (very slick) chat-enabled signing to do multi-person wallets, but the wallet I play with the most is a 2/3 multisig with one key on my phone, one on a tapsigner, and one on a coldcard. I keep the tapsigner in my pocket, so wherever i go if i want to send someone bitcoin its just sign with the phone key, type in my tapsigner pin and tap the card, done. If i lose the tapsigner, i can use the coldcard over nfc to sign or roll to a new wallet.
The satscards have been great to play with too. Nunchuk supports them very well. There are a few advanced features that right now you can only really do with the cktap cli and a usb nfc reader, but for the basic “unseal and sweep” functions, nunchuk works great.
So far the experience has been really great. I’m someone who has played a LOT with multisig wallets on the phone, which usually means scanning animated qr codes between your phone and a laptop, or using a lightning to sd dongle, or using icloud to shuffle psbts around. All of those work but kinda suck. NFC is absolutely magical.
I’m excited to see more apps and hardware support nfc (need to play with it in zeus). I think it will be a big part of mobile bitcoin ux in the future.
