The ultimate slope calculator for landscape architects and builders. Instantly calculate slope, elevation, and distance with built-in field notes and visual diagrams.
SLOPE - PROFESSIONAL GRADE CALCULATIONS FOR SURVEYORS, ENGINEERS & CONTRACTORS
THREE POWERFUL CALCULATORS IN ONE APP
Slope Calculator Input Point A elevation, Point B elevation, and horizontal distance to instantly calculate elevation difference, slope as a decimal, and slope as a percentage. Perfect for grading plans, site analysis, and verifying field measurements.
Elevation Calculator Enter slope percentage, horizontal distance, and starting elevation to determine elevation difference and true elevations in both positive (upward) and negative (downward) directions. Ideal for planning drainage, roads, and accessibility ramps.
Distance Calculator Input slope percentage and elevation change to calculate the horizontal distance required. Essential for estimating project scope and material quantities.
MODERN FEATURES DESIGNED FOR THE FIELD
iCloud Sync Across All Your Devices Your projects, calculations, and field notes automatically sync across your iPhone and iPad through iCloud. Start measurements on site with your iPhone and review them later on your iPad in the office - your data is always up to date.
Organize by Project Create unlimited projects to keep calculations organized by job site, client, or phase. Each project maintains its own set of calculations and field notes, making it easy to reference past work or generate reports.
Field Notes & Shot Naming Save important calculations with custom names and notes. Label each shot for easy reference later - "Property Corner NW," "Driveway Grade," "Foundation Elevation" - whatever helps you stay organized.
Visual Diagrams Every calculator includes color-coded visual diagrams that update in real-time as you enter data. See the slope relationship between points graphically, making it easier to communicate with clients and crew members.
Imperial & Metric Units Switch instantly between feet and meters with a single tap. All calculations and saved data automatically convert, so you can work with whatever unit system your project requires.
Real-Time Calculation Results update instantly as you type - no need to tap a calculate button. The faster workflow means more measurements in less time.
Custom Decimal Precision: You can adjust your decimal display (2, 3, or 4 decimal places) directly in Settings. Ideal for high-precision grading, digital levels, and detailed engineering plans, complete with a live sample preview.

Would be a five if it had a inch input on both measurements
Joe743805
I with you could input both feet and inches into both measurements, that would make this the perfect app. Overall still a good app.
Developer Response
Something we are working on! Thanks for the feedback. As a surveyor, our imperial measuring system is the decimal (tenths)... Builders, like you, may prefer the resultant answer to be displayed in feet and inches...
Glorified calculator
DonMoell
I needed an app that automatically measures distance and slope. This app does the same as a normal calculator; everything has to be put in manually. Not worth the double digit price!
Developer Response
Thanks for the feedback. Many contractors / students / homeowners do not use these types of calculations often enough to remember the formula to calculate slopes, elevations etc. I designed this app for that specific reason. I guess, it is a glorified calculator, but I guess you could say that for thousands of other apps on the app store.I'd like to think the app has a clean easy to use interface that provides worthwhile information to the end user.I'm not sure of any iPhone device having the ability to measure distance / slope accurately without actually using survey equipment. Our app is an end user slope calculator just as the name suggests.
This is a massive update designed specifically for contractors and professionals in the field!
• Tape Measure Mode: You can now input data using architectural feet and inches—perfect for working directly off your tape measure on the job site.
• Custom Pro Keypad: We’ve built a brand-new, customized keypad from the ground up. Whether you are typing in decimals, feet and inches, or metric units, the exact buttons you need are always right there.
• Custom Color Themes: Working in glaring sun or thick fog? Choose from 14 new color themes (including high-visibility options) to ensure your screen is always easy to read.
