Measure and convert roof pitch without slowing down a field check. Roof Pitch Gauge turns a supported iPhone into a clear, stable angle gauge and keeps the essential roofing math together in one private offline utility. FAST PITCH MEASUREMENT • Face-up live angle gauge with a visible stability state • Hold a reading and calibrate zero on a known surface • Manual mode for plans, estimates, and safer ground-level checks • Common 2:12 through 12:12 pitch presets ALL THE CONVERSIONS • Rise and run normalized to 12 units • Roof angle in degrees • Percent slope • Pitch factor for estimating sloped length LOCAL DOCUMENTATION • Save measurements on your device • Name readings and add job or roof-plane notes • Share a concise measurement summary PRIVATE BY DESIGN Everything works offline. There is no account, advertising, analytics, tracking, or cloud backend. SAFE FIELD USE The built-in guide recommends measuring from the ground, attic, plans, or another secure location whenever possible. Never climb solely to use an app, and independently verify critical readings. Unlimited live and manual measurement is free. Roof Pitch Pro is a one-time purchase that unlocks unlimited saved records, editable notes, and sharing—never a subscription.
