Yes, says the developer: version 1.8 is ready for iPhone Duo, and open, Lista switches to the sidebar layout it uses on iPad and Mac.

About Lista
Lista is a to-do list app from Tomatique, a Portuguese studio, for iPhone, iPad and Mac. Lists live in spaces, so work and home stay apart, and any list can be broken into sections. Filters such as Starred, Today and Scheduled work at every level, across everything, in a space or in one list, with nothing to set up. Lists can be shared with family and edited together in real time, and dates typed in plain words (“next Monday”) are picked up as you write. There is no account: Lista syncs through your own iCloud. It is free for two spaces and five lists; Lista Pro lifts the limits for $2.99 a month or $29.99 a year.
Version 1.8 is ready for iPhone Duo, its release notes say. The developer says that open, Lista switches to the sidebar layout from iPad and Mac, with your spaces and lists beside the one you’re viewing; partly folded, the sidebar sits on one side of the fold and the list on the other. In Split View, two Lista windows can sit side by side and items can be dragged between them.
