Not shilling for one particular company, BUT the Keystone hardware wallet has a decent IMO multicoin companion app for both Android & IOS
Didn't Keystone officially announce recently they are stopping support for their companion app and they are focusing more on supporting all other third party applications?
If this is true than I wouldn't recommend anyone using this app for anything serious.
There is one app from different HW manufacturer, but I am not comfortable enough using and recommending it.
If they did I missed it, which is possible.
But, even so a slightly out of date app that is linked to hardware is going to be safer then a software only one.
In the end there are a lot of
BTC only wallets that are good.
And few single alt coin wallets that are good.
All the multicoin wallets are fair at best.
And this then gets back to the amount of risk someone is willing to take vs the amount of funds involved.
