About this app

Designed by tradespeople, for tradespeople. Construction Calc Lite handles the heavy lifting of jobsite math—fractions, dimensional conversions, framing, and layout—so you can focus on the build.

Whether you're a carpenter, concrete finisher, framer, superintendent, or DIYer, Construction Calc Lite delivers fast, accurate jobsite calculations with zero guesswork.

WHY TRADES CHOOSE CONSTRUCTION CALC
• True Feet-Inch-Fraction Math: Add, subtract, multiply, and divide in full dimensional fractions down to 1/16th (or user-set precision) with automatic reduction.
• Seamless Unit Switching: Effortlessly mix Imperial and Metric. Convert feet-inch-fractions to meters, centimeters, or millimeters in a single tap.
• Split-Screen Display: View decimal values, feet/inch fractions, memory registers, and scale factors simultaneously in large, high-visibility text.
• Visual Cut & Layout Solvers: Dedicated modules for right triangles, miters, arcs, and baluster spacing complete with clear visual diagrams.

WAS a great app... Now it SUCKS!! Start entering your numbers and then... without warning, the screen adds a stupid ad at the bottom of the page pushing every button upwards. It does this right as you get ready to tap the "Equal =" key, thus forcing you to click on the stupid ad!! Accident ?? I think not. I even contacted the owner and described the issue, yet he refused to fix it. I guess he is more interested in getting a little kick back from the stupid ad he forces you to click on!! There has to be something better out there!! NOT worth the time!!

You can simply wait for the ad to load before you begin working. The "little kickback" from the ad is the little amount of money we make to produce apps for people who don't want to pay for apps. If you dislike ads then simply buy our paid version that has no ads.
