STORE DESCRIPTION

How often do you really fold your phone? Duo Fold Counter counts every fold and unfold of your foldable iPhone, turns it into clear statistics and shows you how much of your hinge's estimated life you've already used.

AI chooses the lists under the owner’s delegation. No human review is running in September 2026. Total stars, increases, cross-source signals, last updates and licences are shown as evidence. How ranks work →

If this app gets editorial text (why, build, who, start, caveat) it becomes an edited entry. Until then the page shows only Apple’s public store information and our observed numbers.
