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 FOR ROOFERS · CARPENTERS · DIY · CONSTRUCTION · DRONE PILOTS · SATELLITE DISH INSTALLERS · TRAIL HIKERS · GARAGE MECHANICS Available in 14 languages. ## Version history (last 5 releases) ### 1.0.30 — 2026-08-21 Fixed a rare crash that could happen right after opening Clinometer, and made startup more reliable. Angle and slope measuring across Auto, roof pitch, grade, and bubble level modes is smoother and steadier now. Thanks for using Clinometer! ### 1.0.29 — 2026-08-11 The angle is now right whichever way you hold the phone. The app only ever measured tilt across the phone's width. That works if you lay it flat with the slope running side to side — but lay it flat pointing UP a slope, the way anyone puts a phone on a roof or a ramp, and a 30° pitch read 0.0°. Stand it on its long edge against a rafter, the way a clinometer is normally held, and a level surface read −90°. It now works out how you're holding it and measures along the axis you're actually using, in all four positions, with uphill and downhill still telling apart. Calibration behaves too. The trim in Settings used to be added to the angle only, so a 2° trim showed 32° next to the grade of 30° — two numbers on one screen that couldn't both be true. Everything now comes off a single corrected reading. And Reset no longer quietly throws away your zero calibration: it clears the session, nothing else. If you calibrated around the old behaviour, re-zero once on a surface you trust. ### 1.0.28 — 2026-08-06 Ads no longer interrupt you mid-task. Anything full-screen now waits until you have finished what you were doing, and the app stops showing a blank pause where an ad failed to load. ### 1.0.27 — 2026-08-05 New App Store screenshots that show the app as it really looks, plus fixes to what those screens were getting wrong. ### 1.0.26 — 2026-08-03 We fixed a rare crash some users saw on launch, along with performance and stability improvements. Thank you for your patience and for helping us make the app better! ## More apps by Kyu-Hee Jang - [Calculator+ Tip Tax BMI Unit](https://appshunter.io/ios/app/calculator-plus-tip-tax-bmi-unit/id1587591476) - [QR Lens+ Barcode Scanner Pro](https://appshunter.io/ios/app/qr-lens-plus-barcode-scanner-pro/id1590631012) - [Sound Noise Meter+ dB SPL](https://appshunter.io/ios/app/sound-noise-meter-plus-db-spl/id1593197145) - [Tremor Vibration Meter](https://appshunter.io/ios/app/tremor-vibration-meter/id6759666731) - [Lux Light Meter · Photometer](https://appshunter.io/ios/app/lux-light-meter-photometer/id6759858193) - [Barometer: Air Pressure](https://appshunter.io/ios/app/barometer-air-pressure/id6759883097) All apps by Kyu-Hee Jang: https://appshunter.io/developer/1587578867 ## Related topics [clinometer free](https://appshunter.io/ios/topics/clinometer-free) · [clinometer](https://appshunter.io/ios/topics/clinometer) · [car clinometer](https://appshunter.io/ios/topics/car-clinometer) · [vehicle clinometer](https://appshunter.io/ios/topics/vehicle-clinometer) · [tilt angle](https://appshunter.io/ios/topics/tilt-angle) · [benchmark slope](https://appshunter.io/ios/topics/benchmark-slope) · [one be maximum](https://appshunter.io/ios/topics/one-be-maximum) · [dead slope 3d](https://appshunter.io/ios/topics/dead-slope-3d) · [roof angle](https://appshunter.io/ios/topics/roof-angle) · [inclinometer free](https://appshunter.io/ios/topics/inclinometer-free) · [free roof pitch](https://appshunter.io/ios/topics/free-roof-pitch) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
