Does breathfold work on iPhone Duo?
Yes, the developer says so: on the Duo, opening the fold means breathe in and closing it means breathe out, and the orb follows the hinge.
- App Store confirmedKunal Panchal, the developer, in the App Store description for version 1.0 (released October 15, 2026), which says that on iPhone Duo you open the fold to inhale and close it to exhale, with the orb following the hinge.
