I use apple for some of my crypto.

But only certain coins are approved for iOS. And some of the apps work better on Android.

I get tend to get the new Nexus/pixel on the price drop, not launch. And update the iPhone to be 1 or 2 generations behind. The spare phone also acts as 2 factor/multisig.

Also have Mac/PC.

Some developers put something out first on one or the other, and it's fun/useful to have access to the new potentially disruptive apps.
