Crease: Fold Counter & Stats

Crease is built for iPhone Duo. It counts every time you unfold your phone and turns the hinge into an odometer.

Set it up once and forget it. A Shortcuts automation on the Opened trigger runs Crease in the background each time you unfold, even when the app is closed. No pop-ups, nothing to tap.

WHAT YOU GET
• Today's openings, with your streak and a comparison to yesterday
• A six-digit hinge odometer with milestones
• Hinge health: how much estimated life is left, and how many years at your pace
• The last 7 days at a glance
• Time open: average and longest session, with the optional Closed automation
• Widgets for the Home Screen and Lock Screen
• History, with quick fixes for a missed or doubled count

PRIVATE BY DESIGN
No account and no ads. Your history stays on your phone.

A NOTE ON HINGE HEALTH
Apple has not published how many folds the iPhone Duo hinge is rated for. Crease estimates from 200,000 folds by default, and you can change the number in Settings.

OTHER PHONES
Crease is made for iPhone Duo. On other iPhone models it runs as a trial: a double tap on the back stands in for unfolding.
