Scores above the fold and scorekeeping controls below
Does Score Keeper work on iPhone Duo?
Yes, the developer says so: half-folded on a table, big scores sit on the upright half and the scoring buttons and timer on the flat half.
- App Store confirmedZaffles LLC, the developer, in the App Store release notes for version 1.2.0 (released October 6, 2026), which describe a half-folded layout with the scores above and the scoring buttons below, a side for each team when folded like a book, and larger scores when open. The App Store pictures show conventional phone and tablet scoreboards.
