Works on Foldable & Standard iPhones

On foldable hardware, the hinge sensor drives live T-bevel angles, automatic 90° Periscope handoff, and the 5.4" Cover display. On single-screen iPhones (iOS 26+), drag the interactive Vernier dial directly, measure live 2-axis pitch and roll with CoreMotion, and use the 48MP macro loupe with LED torch control.

Built for Dirty Hands & Offline Job Sites

No accounts, no subscriptions, and zero cloud uploads. Every bevel angle, miter table, and stamped inspection photo stays locally on your iPhone until you export a CSV cut list or share an image with your crew.
