DuoAngle – Angle Meter

About

Open your foldable. See the angle at a glance. Duo Angle 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 Duo Angle 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 measurement requires a compatible foldable device and system support. Standard iPhones don’t have the sensor it needs.
