iPad

Open your iPhone Duo. See the angle at a glance. FoldMetry puts the current hinge angle front and center. The number moves as your device opens and closes, with a clean display that stays out of your way. Have a position in mind? Set a target angle and feel a gentle tap when you reach it. Save more than one for the angles you use often. The app follows your device’s Light or Dark appearance, and measurements stay on your device. All measuring features are free. If FoldMetry earns a spot in your day, you can leave a one-time tip to support its independent development. Tips don’t unlock extra features. Hinge angle measurement is available only on iPhone Duo. Other iPhones and iPad can view device support information but cannot measure hinge angles.
