StairCalc - Stair Calculator 3.50

This comprehensive stair framing, decking, flooring, and concrete calculation tool is designed to serve carpenters, contractors, and builders requiring precise measurements and estimations. Its user-friendly interface minimizes complex data entry; users can begin inputting data in any field, with help and guidance accessible via double-tap on buttons.

The application facilitates the discovery of solutions under various restrictions related to tread dimensions, step rise, incline, and specific standards such as '2R+G' or '2R+TD'. Users may choose to apply all, some, or none of these restrictions based on their project requirements. Note: Pre-filled data should be verified against local building regulations, which vary significantly across regions; users should adapt settings accordingly.

Known for its accuracy and reliability, this tool is an essential resource for professionals engaged in stair framing, decking, and flooring construction. Developed by experienced carpenters and utilized worldwide by contractors and builders.

The app supports metric units as well as US/Imperial measurements (feet, inches—decimal or fractional). Tap the icon to switch between units.

This version also incorporates a general calculator designed for construction-related calculations, including a tape measure feature that can be emailed directly.

The features of StairCalc include:

• Stair Framing (for single stair runs): Handles multiple restrictions simultaneously; allows fixed overall stair rise, fixed stair run, or both for maximum flexibility.
• Calculations for number and dimensions of risers and treads.
• Factors such as step incline and stairwell opening.
• Decking & Flooring Setout, Material Estimating, and Costing: - Options for insets and configurations with single or double bearers. - Set maximum, fixed, or equal spacing. - Input material and labor costs to generate total cost and per-area estimates. - Features for printing, emailing, messaging lists, and note-taking.
• Timber Setout: - Calculates and prints list of stud positions. - Supports equally spaced, maximum spacing, or fixed spacing options. - Includes inset at start and end. - List generation with options to print, email, or message notes.
• Concrete Estimator: - Computes quantities for slabs, footings, round and rectangular/square holes. - Estimates total volume and cost considering waste factors.
• Converter: - Allows conversion of lengths, areas, volumes between Metric and US/Imperial units. - Supports decimal units or yards/feet/inches/fraction formats.
• General Calculator with Tape: - Enables direct calculations (add, subtract, etc.) in feet/inches/fractions or decimals. - Provides common functions for quick computations.
• Extensive Help Resources: - Brief help accessible via a single tap at the top of the screen. - In-depth guidance available by double-tapping most buttons.

The application is optimized for all iPhones and iPads running iOS 16.4+ in portrait mode.

Infoguide: This app was developed by a small building firm based in Western Australia. Created by a former roof framing carpenter to assist our team of carpenters. We use it ourselves and believe it will prove equally valuable to other carpenters and construction professionals.
