Major features of Scientific Calculator++ are: 

- Shows the expression as you enter and keeps a history of your calculations. 
- Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations. 
- Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format. 
- Capability of calculating permutation, combination, Least Common Multiple (LCM), Greatest Common Divisor (GCD), and prime factorization. 
- Quadratic and system of two linear equations solver. 
- Rectangular to polar and polar to rectangular coordinate conversion (extremely useful for phasor calculations for electrical engineers) 
- Common physical constants can be chosen from a list and used in the calculations. 
- Throws a set of dice (choice of 1 die to 4 dice) 
- Backspace to delete last digit entered.  
- Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians. 
- Showing the content of memory on MR button, as long as it fits. 

You are going to love the simplicity of the user interface and yet have the powerful functionality with which Scientific Calculator++ is loaded.

### 5/5 — 1

*2013-10-08, version 1.02*

It took a few tries to learn the system but worth it. Glad it is back on with OS7

### 1/5 — Shuts down constantly

*2013-09-24, version 1.0*

Complete garbage.... Keeps shutting down!  Waste of my money and time while helping my daughter complete her math homework.

### 5/5 — Scientific Calculator++

*2013-06-30*

Your app has been tested in the best environment today. It was used by two surveyors at a natural gas plant, with the installation of a vessel used for amine extraction. Millimetre accuracy was required as the vessel was in excess of 30 m tall, and was positioned by two cranes. Rounds and faces were read, and sine calculations were made on the calculator involving distances and angles from 90 and 180 degree positions with two instruments.

The calculations and app were viewed by a superintendent and senior engineer who were very impressed. Well done. This app is excellent and is up to the task required by class leaders in their field. 

I thoroughly recommend this app. It is likely that it will be used again in the field, will definitely be used to complete calculations for university study and has become a valued tool in my kit.

Congratulations.
