Charles Rudolph

Machinist calculator Use it every day. Very handy for angles and hole circles. I am a factory maintenance and die repair man and appreciate this apps simplicity. Machinery handbook is gathering dust.

Rob Wagel

Perfect I use the trig and sine bar functions everyday. Only problem is my phone gets filthy from using it so much.

Aaron rodriguez

Work's good The only problem is just application icon just shows an Andriod icon with Words Machinist calculator under it.

Clinton Schmidt

C. Schmidt I have a no-contract android phone and noticed that when I use this app it disabled my phones power off capability. Had to remove the battery and power the phone back up otherwise it's a great app. Would like to see a grid pattern calculator with it though.

Lalo Arroyo

A Great app, if it's possible, help on how to make a circle program, I can never get it right with the x, y, i & j

Trades Math Calculator September 3, 2014

Hi Aaron, thanks for letting me know. I've had a few people mention issues with the S5 compatibility and am looking into what is the problem, and hopefully be able to get it fixed in a future update. Trades Math Calculator August 5, 2013

It was definitely time for an update, I hope you like the new layout! Please e-mail me with any suggestions/criticisms, feedback from users will help me make this app perfect. Requests below On the speed and feed page, it would be helpful to have a # of flutes box.

Usefull Would have been 5 stars if it had a compound sine plate function

Colby Awesome app! The ability to toggle between metric and inches, A+++!! Only thing missing for me is feed per tooth calculations. Hope to see that soon!

Good Good app, be even better if it could work out ball sizes!

Perfect, maybe a SFM calculator when you enter workpiece material and tool grade in an update? Maybe even throw a drill/tap chart in there?

The small red letters are very difficult to read in the right triangle solver. Would be nice to see more features in a $4 app

Wrong Answers It's always off on angles. Can't figure out how to make it match what the calculator and my trig book says to be true.

Trades Math Calculator December 14, 2013

I'm sorry you're having problems. We have MC running on multiple platforms and have not run into this issue before. Can you post here or email us some specific examples of where you're getting a wrong answer, and I will look into it immediately. Review deleted

# What's New

3 Wire Thread Measure Function Added

Quickly make all the calculations required to measure screw threads using the 3 wire method!

Whitworth (BSW), UN, ISO Metric, Trapezoidal, Acme, and Stub Acme. Uses formulas that give very accurate results for lead (helix) angles generated by single start threads. When measuring threads with larger angles, such as UN or ISO Metric, results will be highly accurate for threads with lead angles up to ten degrees.

## Calculator

Calculator

A simple, beautiful calculator inspired by the iPhone calculator but with added functionality such as skins and layouts. It is designed to replace the rather lame stock calculator with a calculator that looks great while retaining ease of use and intuitive design. Calculator is designed to meet all of your calculating needs!

***Calculator Features***

*Simple, accurate calculator: Leave the calculator in portrait view to see just a simple calculator, or turn the calculator on its side to reveal a scientific calculator

*Calculator Skins: Calculator v.3.0 now supports changing of skins to change the look and feel of the calculator. Choose between and array of different skins to match your favorite phone OS including iOS, HTC Sense and Samsung Galaxy. Also if there is a certain skin you would like to see made for you, don't hesitate to send an email!

*Different calculator layouts: Choose between 3 different calculator layouts. 1) Default Layout for a standard 10-key calculator in portrait mode and scientific calculator in landscape. 2) Business Layout adds a '%' key in portrait mode and a '00' key. 3) Simple Layout keeps the 10-key calculator in both portrait and landscape mode when all you need is a simple calculator.

*Memory Buttons- Fully functional 'M+', 'M-', 'MR' and 'MC' calculator buttons. Calculator will remember the value stored in it even if you leave the app.

*Landscape calculator: Turn your phone on its side to reveal a scientific calculator with advanced functions like square root, exponents, factorials and more.

*Trig calculator: The landscape calculator even features full support for trigonometric functions. Calculator can take Sin, Cos, Tan, inverse trig, and hyperbolic functions and can calculate in both Radian and degree mode. Great for use in algrebra and other math classes.

*Calculator looks great from the smallest to the largest screens as well as low and high density screens. Calculator also works on the Galaxy Tab!

*App2SD- You can install Calculator to your SD card if using Android 2.2+

## Measure Threads with 3 wires

Sometimes it is not possible to use a thread measuring micrometer to measure screw threads, so the measure over three wire method must be used.

Use this application to quickly and easily do all the calculations required to measure ISO metric and UN 60 degree threads, Acme and Stub Acme threads, and Trapezoid threads with wires. The only thing it can't do is help you to hold the three wires in place AND use the micrometer at the same time!

You start with the nominal thread size, thread pitch (or TPI) and wire size.

You cancalculate pitch diameter or measurement over wires or both.

The thread measurement over wires calculator will also give you the best wire size.
