Before you choose

Consider

NGRAVE ZEROA new wallet starts with Perfect Key, and ZERO can display its equivalent 24-word backup after setup. GRAPHENE is optional; you still need a computer for firmware updates.

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.
