THE most advanced, feature-rich, intuitive & user-friendly construction app available. Capable of handling even the most demanding construction projects.

With its easy-to-use layout & features, it blows expensive stand-alone construction calculators out of the water; and at a fraction of the cost!

Whether an experienced tradesman or novice DIYer, you will find Carpenter’s Helper the perfect companion for every project, in the office and in the field.


• 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.

• 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:

-Conc. Block
-Fencing (Imperial-Mode Only)
-Decking (Imperial-Mode Only)
-Wall Framing (Imperial-Mode Only)
-Board Feet Calc. (Imperial-Mode Only)

You can also export all of your QJ data to be included with a Project, or export separately.

Full use of Screen, but Not as Great

There a A LOT of bugs now with Projects. And taking away adding items to notepad from everything isn't a good improvement. Hope that returns soon with bug fixes with a new update sooner than later. The screen looks so much better now than it did before, so thank you very much for that. The functions that are there, I wish was customizable. Like replacing some functions for Length, Width & Height, & Shortcuts. I don't use pie or square root very often. So those are just wasted space now. Over all it wasn't a super great update, & would rather have the older version v/s this one.

Still my "go to" app

I recently upgraded back to an iPhone and previously three years ago I had this app and it was great. still after three years of having multiple types of devices and going back to an iPhone this is by far my favorite app for any type of construction equations

I don't like the update.

Before you could save dimensions you used often to the notepad and then just touch the dimension to copy it to the calculator. This was the whole reason I liked this app. I do a lot of pipe fitting and I had all the dims of my fittings in the notepad so I could just touch the description of the fitting I needed to calculate. Now all the notepad does is takes notes. This app is worthless to me now.
