## What is Workman's Calculator Pro?

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.

### 5/5 — Review

*2026-07-21, version 1.4.3*

Great app but need to add 1/8 to the fractions

### 1/5 — Be more intuitive!!

*2026-05-15, version 1.4.3*

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

### 1/5 — Struggles with fractions

*2025-09-01, version 1.4.3*

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.

### 3/5 — Multiplying Fractions

*2025-07-02, version 1.4.3*

This app does not multiply fractions properly. For instance 1/2 x 1/2 is 1/4 the app doesn’t give an answer at all. Another example was 3/16*2 7/8 is 9/16 the app says the answer is 1/16th. Have countless issues with multiplying fractions which is why I bought the app.

### 4/5 — Great app

*2025-04-06, version 1.4.3*

Unfortunately I just switched to android and I can’t find this on the play store please consider uploading it there

### 4/5 — HISTORY!!!!!

*2025-02-24, version 1.4.3*

Need to add a history tab to save measurements so we don’t have to continuously write them down or re do the measurement

### 5/5 — Save Time

*2025-01-11, version 1.4.3*

Jonathan.Desjardins

### 5/5 — Use it almost every day

*2025-01-08, version 1.4.3*

Makes fraction math with measurements a breeze. I recommend this app to everybody I work with

### 5/5 — Really really nice

*2024-11-14, version 1.4.3*

Amazing

### 1/5 — No fractions

*2023-02-19, version 1.4.3*

Does not calculate fractions poor decision to purchase
