## What is EduCalc Pro?

The EduCalc Classic app, rewritten from the ground up:

-- All screens have portrait and landscape
-- Polynomial solver up to 10th degree
-- Wide range of settings for font sizes and graph line widths
-- Updates to this version will be more frequent, going forward
-- Matrix calculator more intuitive and is integrated with main calculator screen
-- Table has an "ask" mode where you enter input values and it gives you the outputs.
-- Please report bugs to the email address inside the app


Features:

1)  Scientific Calculator.  A lot of thought has gone into the design of the keyboard, which gives you everything you need while keeping the keys as large as possible.  Available functions include the following:

• the usual arithmetic functions and exponentiation.
• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution.
• Define and name your own constants
• Summations
• Complex numbers!
• Sig figs (enable under settings)
• Programmable keys (enable under settings)

2)  Graphing.  Capabilities:
• Graph up to nine equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
• Can graph in polar coordinates.
• Can graph parametric equations.
• Can graph parametric equations.
• Can graph implicit functions, such as x^2+y^2-4=0.  Most calculator apps can't do this!

3)  Vector and Matrix calculator.  Vector dot and cross products.  Multiply and add matrices.  Determinant, transpose, Eigenvalues and Eigenvectors.  

4)  It can make a table of the values of any function you care to enter.  You can choose the starting x value of the table, as well as how much x increases for each successive row.

5) Triangle solver.  Enter three sides, two sides and an angle, or two angles and a side, and the solver calculates the rest.

6) Polynomial solvers.  Find the roots of a polynomial, up to 10th degree.

7)  System of linear equations solver.

8)  The  reference hits the high points of the following subjects:
algebra, calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.  So if you need a reminder of a trig identity . . . or the quadratic formula . . . or the chain rule from calculus . . . and so on, it's right there for you.

9)  A unit converter.  Your data are in meters, and you need an answer in feet?  No problem!  With a tap, you can enter the result of your conversion into the calculator.  Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume.  Great for physics problem sets!  You can also define your own units.

10)  Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc.  Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value.  Again, great for physics problem sets!

11)  Statistics mode, including options for scatter plots and for regression lines.

12)  Works on both iPhone and iPad.

13)  Derivatives! (Answer simplification is limited.)


I'd love to learn about your comments or suggestions.  You can write me at the email address on the settings screen of the app. Thanks!

### 5/5 — Amazing calculator app!

*2025-09-22, version 10.5*

This is a very impressive calculator, all the more so for being written by a single developer.  Tons of features yes, but it’s the internal functionality that really amazes me.  Try entering 10^100+1-10^100 and arcsin(arccos(arctan(tan(cos(sin(9)))))) into another calculator or calculator app.  Most will get these wrong because of floating point rounding errors.  I would love to see how this app actually handles things.  It must be some combination of symbolic and numerical calculations.  Again, really impressive stuff.

### 5/5 — Great for engineers

*2025-05-28, version 10.5*

I use this almost every day for work and personal projects and it has everything I could ask for in a calculator!

### 5/5 — The only calculator you'll ever need

*2023-06-12, version 10.5*

Does so much, very streamlined for the most part. I use it for multi-step calculations regularly and there's nothing quicker. Would like to see base conversion added as a feature.

### 3/5 — Love the app, needs some fixes

*2023-05-09, version 10.5*

I love this app and have been using it a long time. I used to use the free version but bought the pro mostly to support the developers but I have to use the free version for some things. For example, when I try to use Days Between Dates it immediately crashes the pro version but not the classic version. This app is great but needs some updates

### 3/5 — Please update i really need this app in my life :(

*2020-11-24, version 10.5*

I’m mostly writing this revoew in hopes that the dev sees. Ive been using this app for years as my graphing calucluator, and its amazing. However since updating my phone it doesnt work, and i can’t even get to setting in order to write the developer directly. I hope this is a bug that gets fixed quickly, and that the deceloper is alright

### 5/5 — The only calculator app you'll ever need

*2020-09-08, version 10.5*

I've had this calculator for years and I'm still finding out about new things it can do to this day. It's gotten me from algebra through three levels of calculus and made it all so simple. The size of this thing is insane, there's so much to explore and it can store a ridiculous number of graphs/matrices/data sets all at once. It's easy to customize and tune it to any type of math that you're doing at the moment so that your most used functions are always just one touch away. Seriously, just install it and you won't need to download another one ever again.

### 5/5 — Nice Calculator

*2019-11-09, version 10.4.2*

I am a real user of this app and it is a good one.  It puts all of the power of a scientific calculator on your cell phone.  Super easy to use: you can see all of your calculations, edit them, and reuse them.  Kudos to the developer.  Keep up the great work.

### 5/5 — Excellent.

*2019-10-23, version 10.4.2*

Simple, reliable and versatile. Unvaluable app for Math students.

### 5/5 — Best Graphing Calculator

*2019-07-19, version 10.4.2*

Input is on a separate tab from the actual graphing so input won’t cloud up the screen, and you can zoom on each axis independently. It can graph implicit and explicit equations (up to 20 explicit!). And it can graph derivatives and integrals for you, so you don’t need to find their analytical form ahead of time. Last, it supports user defined functions. Great!!

### 5/5 — Very good app

*2019-03-12, version 10.4.2*

Fantastic app . So much info. This app is well done. Help me and my kids a lot. Thank you
