How do I add my iPhone to CRV?

How do I add my iPhone to CRV? I'm really interested in cryptocurrency and I've heard that CRV has some interesting features. Could you guide me through the process of adding my iPhone to this platform? Is there an app that I need to download? Or are there specific settings I need to adjust on my phone? I'm a bit new to this, so please explain it in a way that's easy to understand. Also, are there any security measures I should take to ensure the safety of my crypto assets? Thank you for your help!
