Builder's Helper - Advanced Construction Calculator

By My Pie Interactive

Open iTunes to buy and download apps.


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.

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:

-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.


With Builder’s Helper, you’ll always have the calculating power you need on you, every time you need it. And with all of the additional features, you’ll be able to take estimating, take-offs, & on-site job performance to a whole new level!
