Fold Counter open on an iPhone Duo: 52 unfolds today, a 7-day bar chart and the hinge wear card

Your habits, day by day

The last 7 days on the main screen, 30 days in History, and weekly totals.

Know your hinge wear

Folds a year at your pace, and how long 200,000 would take. Clearly marked as an estimate.

Today, at a glance

A mechanical-style counter ticks up each time you open the phone, and starts again at midnight.

Easy on the eyes at night

Follows your iPhone's light or dark appearance.

Thirty days back, one tap away

Tap the chart on the main screen to open History. Every unfold is stored with its time zone, so your days stay right when you travel.

How it counts

Live, while it's open

Each time the hinge goes from closed to open, the counter ticks once. Stopping halfway on the way open doesn't count twice.

In the background, with Shortcuts

Two Opened or Closed automations log folds while the app is closed. Setup takes a minute, and the app walks you through it.

Fills the gaps

If a fold slips through, Fold Counter compares the hinge with how you left it and logs the difference when you come back.

Good to know

Stays on your iPhone

No account, no analytics, no servers. The App Store privacy label reads Data Not Collected.

$1.99, once

No subscription, no ads, no in-app purchases.

Made for iPhone Duo

It reads the Duo's hinge, so it needs an iPhone Duo with iOS 27.1 or later. Background counting needs iOS 27.2.
