ConstCalc is a modern construction calculator designed for builders, carpenters, contractors, renovators, estimators, and serious DIY users who need fast, accurate results in the field and at the desk. It combines everyday calculator functions with construction-focused tools in one clean, efficient app, making it easier to handle feet, inches, fractions, decimals, conversions, and material calculations without switching between multiple apps.
Built around real jobsite workflows, ConstCalc makes dimensional math simple. You can work directly in feet-inch-fraction format, switch to mixed or advanced calculation modes, use scientific functions when needed, and instantly view secondary result formats such as inch fractions, decimal inches, metric values, and FT-IN fractional breakdowns. This helps reduce mistakes, speed up layout work, and make results easier to read for different trades and preferences.
ConstCalc also includes a powerful conversion system and a growing set of construction tools for practical estimating and layout work. Depending on your workflow, you can use it for framing calculations, roofing layouts, stairs, cut lists, drywall and sheet goods, concrete and rebar planning, board foot and weight calculations, and other common jobsite tasks. The app is designed to keep important information accessible, with result history, customizable display preferences, theme support, and an interface that stays focused on speed and clarity.
Available for Android and Windows, ConstCalc is made to support both mobile jobsite use and desktop planning. Whether you are checking a quick measurement, solving a mixed-unit equation, preparing material estimates, or reviewing layout details, ConstCalc gives you a practical, professional tool built specifically for construction work.
