Machinist approved This app is well worth the money. Even though the guys I work with and myself learned about chords in school none of us could remember how to calculate them. This app is a chord calculating genius.

Pocket Geometry was voted #13 in Math category in Mobile Learning in Action! See all apps here: http://bestonlineuniversities.com/favorite-mobile-learning-apps/

Simple and easy to use geometry app that you can carry in your pocket!

Calculate the perimeter, area, surface or volume of various geometric shapes.

Shapes includes 2D (square, rectangle, circle, triangle, trapezoid, parallelogram)

and 3D (cone, pyramid, sphere, cube, cylinder and rectangular prism)

If you are willing to help me translate this app into your language, send me an email ;)

## Circle and Arc Setting Out

NOTE: Might not be working on some Android 5.0 and above devices!

Take measurement from your target/surface in prism or non-prism mode, enter received (x,y) coordinates in [Ex] and [Nx] fields and see how far and which way to move your mini-prism/target - inside (towards circle center point) or outside (away from center point).

Circle App works with Units in Decimal Format.

N.B. Always check your Setting-Out and Calculation with different methods and common sense. Neither Developer nor Distributor of this program can NOT and will NOT be hold responsible for any mistakes which happened as a result of using or not using this program. By downloading and installing this program you agree to it and accept your own full responsibility.

## Machinist Mate

Machinist Mate is a collection of all purpose fabrication tools.

This is what the app currently has to offer specifically for machinists:

Speeds Calculator in metric and standard.

Feeds Calculator in metric and standard.

CNC Codes - all the common G and M codes as well as the Letter Address.

These are the all purpose additions:

Conversions - Length and Volume as always in metric and standard.

Geometry - Right Triangle, Obtuse Triangle, Square, Circle, Trapezoid/Trapezium(for those in the UK), Parallelogram and Rectangle.

Reference - Metric to Standard wrench conversions, for when you need a standard but you only have a metric, it shows you how close in size they are to each other. Also in the Reference section is a drill chart; complete with wiregauge, standard, metric and letter sizes.

## Universal Triangle Solver

This application is an universal calculator for triangles. When you give three parameters (sides or angles), this tool computes the remaining parameters and the area of triangle.

The triangle thus determined is displayed with its height.

The triangle thus determined is displayed with its height.

It works with any right or non-right triangle, including the ambiguous case of the law of sines (the two solutions are given). Support angles in degrees, radians and grads.

Useful for trigonometry, roof computations, math, homework or CNC.

Feel free to email developer to request features, localizations, or anything else !

Simple and effective, and available for free !

## Arc Radius

NOTE: Might not be working on some Android 5.0 and above devices!

With this program you can calculate Radius of Arc if you know either:

- Length and Height of the Arc;

or

- Length of Chord and Angle of the Arc;

or

- Length and Angle of the Arc.

This program is working with Metric data.

## 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.
