NetNewsWire 7.2 for iOS has passed App Store review and is available or soon will be.
It has the same hide-unread-counts feature the Mac app has — you can hide them entirely or replace them with a dot. See the settings screen, Appearance section.
It also fixes a bunch of bugs — see the release notes for the full scoop — including one we’ll call out specifically: where the releases notes say “Sped up Today and unread count queries” the notes are underselling a pretty big performance enhancement and battery-use fix during refreshing.
