MACWORLD **** "inchCALC+'s ease of use coupled with its advanced features make this an uncommonly good addition to a crowded genre." 3/9/09

inchCALC+ is a State-of-the-Art Construction Calculator / Conversion Calculator for people who work with the FEET• INCH• FRACTION dimensions used on common rulers and tape measures.

These dimensions are shear drudgery when you have to manually add or subtract them --- let alone multiply, divide or convert to other measurement units.

If you are a builder, contractor, sub-contractor, architect, engineer, artist, designer, student, homemaker or DIYer, you know the importance of working with accurate dimensions. inchCALC+ transforms your iPhone / iPod Touch into a FT• IN• FRACTION construction calculator that inputs and outputs dimensions exactly as they appear on a tape measure.

Dedicated and held construction calculators with similar functions are very expensive. With inchCALC+ you can inexpensively perform the functions of those calculators on your iPhone / iPod Touch.

Easy conversions to other measurement units:
-decimal inches
-decimal feet

Built-in TRIANGLE FUNCTION -- Enter any two &
inchCALC+ automatically solves for the other two:

Selective Keyboard Orientation for Left Handed or Right Handed users

-inchCALC for quickly working with simple measurements
-inchCALC+™ for working with more complex problem solving
-Built-in Functions: √2, X2, π, %, +/-

Great but missing a few simple things

Been using the free version for years but need to do calc for run, rise, diag. The app handles it easily but you can’t store the results or do further math with the results. For example. Calc the diag of 4x4s 8’ apart. Easy but now subtract the diag of the 4x4s to get the inside measurements. Can’t do that. Can’t even save either diag measurements. Need a good memory or paper and pen. Hopefully a future enhancement. Love the app anyway.

Not bad, could be better

There are a lot of great things about this app that I love. I love that it’s simple, easy to use, and for me, super handy.
The downside is I can see this app has not been updated to fit any screen since iPhone 4.
Also, there needs to be a back space. I cannot tell you how many times I’ve input the wrong measurement just to have to start all over again.
I think that would be a good start in fixing this app

the PRO version, INCHCALC+, includes both "Clear Entry" & "Backspace" key -- hope that soles your issue

Hands down best inch calculator on the App Store

I have tried several different architectural calculators and this one is still my favorite for years. Only thing I would like to see added is a history view option, which would make it even better.
