Does Penvo work on iPhone Duo?
Yes. Penvo's App Store page says it supports iPhone Duo, so the update is out. FoldHunt's editor hasn't seen it running yet.

About Penvo
Penvo logs spending by voice: say “four fifty for coffee” and AI files the amount, category and note. Its developer rebuilt the large-screen layout for version 4.8.0, and a post on X shows the open Duo with three columns: ledgers on the left, entries in the middle, spending stats on the right. The same layout is used on iPad. The developer hasn’t shown the closed phone.
