Features & Capabilities

The calculator has been rebuilt, and it's built for the trades!

Workman's Construction Calculator is the best, and simplest construction calculator available on the App Market. With the most intuitive way to calculate measurements. Work with Feet, inches, yards, meters, and regular numbers. Simultaneously!

Never before has a calculator worked like this!

Do you want to put in 3/16 of an inch? Press the numerator button, click 3, and click 16 afterward, done. Yes, 16.

One of the unique parts of Workman's Calculator is that the buttons change. When selecting a numerator only odd values are shown (1, 3, 5, 7, 9). After clicking one of the values the appropriate denominator values appear. If the numerator is 9 or higher, automatically 16 is selected. The denominators will always be more than the numerator.

Need to multiply by a decimal? Go ahead.

Choose how you wish to view your calculations.

• Feet • Inches • Decimals

Workman's Calculator is about being quick and getting you your calculations that you need, so there's more time getting done what needs to be done and less time on the phone.

User Reviews

Users praise the app for its field-ready feel and usefulness for fraction-based measurements, especially in carpentry and trades. However, recurring issues include unreliable fraction calculations, fraction input limitations, and occasional stability problems. There are repeated requests for more features (Apple Watch support and enhanced input options). Overall, it’s valued for quick field calculations but is marred by accuracy and usability gaps that frustrate professional use.

Pros

Quick and easy to use; a must-have for field work.
Makes fraction-based measurements easy and saves material waste in trades.
Supports feet/inches and decimal input, which fits carpentry and construction workflows.
Highly recommended in trades and apprenticeships; seen as essential for in-field calculations.

Cons

Fractions math is unreliable or buggy (wrong results or no answers for multiplication).
Input limitations for fractions (cannot enter mixed numbers; limited denominators; requests for more options like /32 and /64).
Stability issues (app sometimes won’t open or crashes).
Missing features/requests such as Apple Watch support and additional input features (e.g., parentheses) that users frequently ask for.

Recent reviews

App should be more intuitive. I can’t put a fraction

by Ma*****, 2026-05-15

To say it struggles is a bit of an understatement, though. When trying to subtract two mixed numbers, I couldn't enter Int and 1/2, for example. I don't know if it would have calculated it correctly, because I couldn't even enter it. It only offered the option of entering 1/3, 1/5, or 1/1, weirdly. Really disappointing for a calculator that exists specifically to enter these types of calculations.
