Can I save my Hio Contacts to my phone?

Yes!

Go to your People tab (bottom left icon), and from their profile, tap the (...) button at top right. This will display a list of options. Select the option "Save as a Contact" and they'll be saved to your device.

Oh, and we'll save everything they've sent you to the device as well: contact info, socials, when you met timestamp, and notes!
