Before you choose

Consider

imKey ProSetup starts in imToken, and COS firmware updates require USB to a computer. Save the binding code for pairing with a new phone; it is separate from the recovery phrase.

BitBox02 NovaOn iPhone and iPad, Bluetooth carries the data but the wallet still needs a physical power connection. You control it by touching its edges, not the screen. BitBoxApp on iPhone and iPad guides firmware updates when a compatible version is offered.
