## Description

Concrete, stairs, spacing and more. Get 16 practical calculators with clear diagrams, feet-and-inch fractions and metric units. All tools included.

A practical construction calculator for carpenters, builders and contractors. Work out concrete quantities, stair dimensions and baluster spacing from the measurements you already have.

Whether you're framing a wall, planning a deck or estimating a concrete pour, Calc Tools brings 16 everyday calculators together on your iPhone and iPad. Choose a tool, enter your dimensions and get a clear result with a diagram to guide your measurements.

PLAN YOUR NEXT JOB
• Concrete: estimate slab volume or concrete for round posts, holes and circular pads, including a waste allowance.
• Stairs: find riser and tread counts, riser height, total run, pitch and an overall stringer-span estimate.
• Balusters: work out a count and equal clear gaps from your span, baluster width and maximum gap.
• Decking: estimate board count and total purchase length with an allowance for waste.
• Gravel, soil and asphalt: estimate volume for paths, beds and other projects. Use your chosen density to calculate gravel or asphalt weight.

CHECK DIMENSIONS AND LAYOUTS
• Check Square: find the diagonal, area and perimeter for a rectangular layout.
• Right Triangle: solve missing sides and angles from the measurements you know.
• Pitch: calculate slope and angle from rise and run.
• Equal Spacing: lay out evenly spaced points by count or target spacing.
• Raked Wall: calculate full wall heights at stud positions from heights or pitch.
• Running Dimensions: turn a starting measurement and interval into a list of layout marks.
• Dumpy Level: calculate reduced levels from benchmark and staff readings.
• Area: calculate rectangular area with an optional waste allowance.

METRIC AND IMPERIAL MEASUREMENTS
Work in millimeters, meters, inches, or feet and inches. Enter mixed fractions and choose inch display accuracy from 1/2 to 1/64. Convert your entered measurements between units while retaining their full calculation precision.

READY WHEN YOU NEED IT
Calculations work offline. Find a tool with search and categories, keep favorites within reach, and save named calculations with their inputs and results. Reopen a saved calculation or share the result with your crew.

All 16 tools are included. No account, subscriptions or in-app purchases. Light and dark appearances keep the interface clear on iPhone and iPad.

Results are estimates. Verify dimensions, material allowances and local building requirements before use. Raked-wall heights and stringer spans require separate cutting and fitting allowances.
