Opti Clinometer
Slope meter for the field
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Opti Clinometer turns your iPhone into a precise field clinometer — a modern alternative to classic optical instruments.
TWO MEASUREMENT MODES
• Sight mode: hold the phone horizontally at eye level and aim along its top edge, like a classic clinometer. The right-hand end points at your target.
• Camera mode: aim with the on-screen crosshair and read the slope to whatever you are looking at.
SIMPLE BY DESIGN
Tap the screen once — the reading freezes and is saved. Tap again to resume. That is the whole workflow.
BUILT FOR REAL FIELD WORK
• Rotating artificial horizon and bubble levels help you hold steady
• Color-coded slope scale: green below 8%, yellow 8–15%, red above 15%
• Optional measurement photos with a viewfinder HUD
• Coordinates saved with measurements and a satellite map
• Measurement history with notes and CSV export
• Readings shown in both percent and degrees
