Check a surface is level with Level, or aim at a roof or tree with Sight. On first launch, the opening screen now waits while you answer the privacy questions.
Clinometer+ turns your iPhone into a slope, angle and roof pitch meter. Open the app and the live angle is already on screen — lay the phone on a rafter, a ramp or a deck board and read it in degrees, percent grade and 1:N ratio at the same time.
▶ FOUR WAYS TO READ AN ANGLE
• Auto — round gauge with degrees, grade % and ratio, plus a live row for x:12 pitch and mm per metre.
• Roof Pitch — rise:run (4:12, 6:12…) with the nearest standard pitch from 1:12 to 12:12.
• Slope — grade % with walking categories and references such as the ADA ramp limit (1:12) and a safe ladder angle (75°).
• Tilt — bubble view with ± degrees and a clear level indicator.
▶ HOLD IT ANY WAY
Lying flat on a surface, standing on its end, or on its long edge against a stud — the app detects how the phone is held and shows it. If it guessed wrong, tap the chip to switch. Uphill and downhill are told apart.
▶ TARGET CHECK
Pick a target — ADA ramp, drainage fall, driveway, shingle roof or stairs — and a PASS / OUT OF RANGE badge updates live while you adjust.
▶ RECORD, HOLD, ZERO
• Start records a session: min / max, elapsed time and a live trend chart. Stop saves it to History.
• Hold freezes the number so you can read it off a tight spot.
• Zero on any surface you trust; the offset is kept after relaunch and a long press clears it.
• Optional vibration when the angle crosses 0°.
▶ MORE TOOLS
• Bubble level — two-axis roll and pitch for shelves, floors and appliances.
• Vehicle — roll and pitch gauges for off-road driving, with Zero here, max values and a warning angle from 5° to 60°.
• Miter & Crown — miter and bevel saw settings for crown moulding from the corner and spring angle (38°, 45°, 52°), or a simple baseboard miter. Capture the corner by holding the phone against each wall.
▶ HISTORY
Up to 500 saved readings with notes, favourites, side-by-side compare and 7-day stats. Export everything as CSV, record a one-per-second log, or share the current reading as an image.
▶ GUIDE
Short notes on measuring roof pitch, ramp rules, the two-sided calibration trick and the difference between degrees and percent grade.
Readings are shown to 0.1°. Phone sensors vary and cases or bent frames add error, so zero on a known level surface before critical work.

• On first launch, the Clinometer+ opening screen now waits while you answer the privacy choices form or the tracking question.
• On later launches, Clinometer+ gets past the opening screen faster.
