Clinometer+ Slope

Clinometer+ Slope turns your iPhone into a precise angle and slope meter with four purpose-built modes — and now keeps a full history of every reading.

FOUR MODES
• Auto — radial gauge with degrees + grade % + ratio.
• Roof Pitch — rise:run (6:12 etc.) + degrees + standard pitch matching (1:12 ~ 12:12).
• Slope — grade % + walking categories (level / gentle / moderate / steep / severe) + ADA ramp / ladder safe references.
• Tilt — bubble level visualization + ±degrees, perfect-level indicator.

WHAT'S NEW
• Measurement History — every reading is auto-saved with a 7-day trend chart and insights like "+12% vs your 7-day average".
• Notes & Favorites — add a note ("kitchen floor", "patio") and star to any saved reading.
• Compare Mode — pick two saved measurements and view the difference side by side.
• Reference Library — ADA ramp max (1:12), standard roof pitches (3:12 / 6:12 / 8:12), ladder safe angle (75°), ramp categories, climbing slopes.
• Share Result — share your current angle as an image.
• CSV Export — share all your measurements as CSV for spreadsheets.

CORE FEATURES
• Real-time angle measurement (degrees / grade % / ratio)
• Kalman-smoothed sensor readings
• Hold function (freeze current reading)
• Calibrate Zero (set any surface as the 0° reference)
• Min / Max tracking with elapsed time
• Live trend chart
