In that case would you recommend any particular wallet preferably to use on my iPhone X and iPad.
I just noticed that you're ios user of mycelium, just inform you that app too outdated and might assume was abandoned by mycelium while its android version is up to date.
Now, for suggestions, I can suggest only by what others using since I'm not an iPhone user, you can install blockstream green wallet which was former green wallet, it can be used fwith hardware wallets such nano s and trezor, while it has nice ui.
