smartphone required?

Is it correct that a smartphone is required to setup the Mini 2?

With the original Mini there was an inReach @ Sync desktop app but with the Mini 2 that app is no longer listed in the Update / Sync section on the Explore website.

My dad does not have a smartphone and is about to return the Mini 2 since there seems to be no way to sync the various settings/msgs to the Mini 2 without a smartphone and this was not clear in any review nor the Garmin product info... :(
