Currently, we don't support any other devices besides iPhone.
This is because our main priority is to keep your crypto-assets secure.
We rely on a piece of security tech in the iPhone called the "Secure Enclave" and laptops and tablets don't have this. Read more about it here.
The new MacBook Pro, new iPads, and some other devices have similar technology and we're working hard to see if we can support these in the future.
In the meantime, you can view your accounts on other devices using a block explorer. and soon it will also be possible to submit draft transactions through our web API.
