As of March 24, 2020, there was no Dual-fisheye Plug-in remote for iOS. The developer, @hirota41, mentioned that he was getting feedback from Android users first, then planning to work on iOS. This message was from late March, so pretty recent.
Please refer to the topic I linked to above for Bluetooth clicker info. Not all the Bluetooth clickers work and RICOH listed only one on their support site.
