Features:

• Calculator: Includes all of the features you would expect to find on an advanced Construction Calculator, but redesigned and optimized for the touch screen. 

Easily calculate linear, square & cubic measurements in English (Yards, Feet, Inches, Inch Fractions [up to x/128”]) & Metric (Millimeters, Centimeters, Meters), and convert easily between the two unit modes with a convenient [E/M] toggle.

Store & recall triangular measurements to calculate roof pitch, rafter lengths, stair lengths, and more with the convenient [Pitch], [Rise], [Run] and [Diagonal] buttons. When any 2 values are stored, the other 2 are generated automatically!

The [Tape] feature keeps an easy-to-read list of your calculations for error-checking, while the Memory Bank feature allows you to Add, Subtract, and recall stored values with a running ticker displayed in the LCD area.

Plus we just added a NEW Quick-List feature, which allows you to label and store often-used values for quicker entry into your equation!

• Notepad: Keep important notes within one tap of your calculator, supporting multiple pages and exporting to PDF.

• Projects: 
Create lists of data in Text-Only, Simplified, or Detailed lists, and store in organized Projects. Useful for take-offs, estimating, budgets, material lists, etc. Lists can even be tabulated to include running totals on the bottom!

Not only does it keep track of important project info & create powerful lists, but you can also store project documents (like budgets,  contracts, plans, etc.) & images (either by attaching images from you photo library or taking new ones).

And of course you can Print or export your Project data via email as a PDF!

• Quick-Jobs: Graphical interface to easily calculate all kinds of construction projects, large or small. With just a few known parameters, Quick-Jobs will automatically fill-in and calculate the rest of the project for you.

These Quick-Jobs are included:

### 1/5 — TIME TO UPDATE THE APP, yes??

*2026-06-11, version 1.24*

June 2026 and no updates since 2023?? What a shame. 
—————————————
Abandoned. Still no sign of an update. 

Contact with the developer indicated that there would be an update to resolve display issues and modernize the app for the latest MacOS version. But nothing has been done, and this once-fabulous app is now a ghost of its former self. Too bad. Avoid it.

### 5/5 — Bh max

*2026-05-19, version 1.24*

Muy buena la aplicación es una maravilla

### 1/5 — Abandoned. Still no sign of an update.

*2025-10-26, version 1.24*

Contact with the developer indicated that there would be an update to resolve display issues and modernize the app for the latest MacOS version. But nothing has been done, and this once-fabulous app is now a ghost of its former self. Too bad. Avoid it.

### 1/5 — Badly broken, not updated at all

*2025-01-10, version 1.24*

I’m so bummed that this app used to be amazing. Even though it’s not rated for desktop use on MacOS, its basic features are totally lacking. The way fractions are displayed on the screen is just a mess, and it’s been way too long since they updated it. It seems like the developer has completely given up on this app.

### 5/5 — Best

*2024-12-24, version 1.24*

Flat out, best construction calculator there is.  I bought CA Industries for my android, but when I switched to Apple, I’d have to spend $60 for their app.  1/6 the cost and a better interface.

### 5/5 — Very usefull

*2024-01-19, version 1.24*

Very easy to use and handy

### 5/5 — Excellent

*2024-01-14, version 1.24*

Excellent

### 5/5 — Good

*2023-10-21, version 1.24*

Good perfecta para la constrution

### 5/5 — Great calculator

*2023-04-14, version 1.24*

I use this constantly for work (woodworker).  It’s the best fractional calendar I’ve used on the iPad and exporting dimensions as a note is very handy.

### 1/5 — Don’t Buy This It’s Garbage

*2023-03-13, version 1.24*

I realized that this was what I was hoping it would be after 5mins of using it. I contacted them about a refund with no response. This company sucks. Waste of money, poorly designed and no customer service.
