Opti Clinometer
Read full descriptionHide full description
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 NO NONSENSE No ads, no accounts, no tracking. The app collects no data at all.

Verdict
The clearest difference is in-app purchases: Opti Clinometer at none against Measure Angles's 10. Opti Clinometer also leads on ads (none vs shown) and update cadence (every 2 days vs fortnightly). Measure Angles's advantage is device support (3 vs 1). On price and iOS requirement there is nothing between them.
