It is possible to move karma, Jodels, replies, pins and settings between Android and iOS devices.
To do so, please take one of the phones and use the "Contact Us" form in the Jodel app. For Android, go to "My Karma" -> "More" -> "Contact us". For iOS, click on "Profile icon" (bottom right) -> "Gear icon" (top left) -> "Contact us". This way, our Support will get information about data which should be transferred to your other phone and will assist you further.
