Solve Equations In New Ways

Equations can be rather scary, but these apps help you find the solution in all new ways.


Point, scan, and solve equations easily


Scan and solve

For those who want a fast and thorough way to solve equations on their homework assignments.

Photomath is a smart calculator app that does something unique and special, and is an invaluable tool for students. Just launch the app, point your camera at your equation, scan it, and Photomath will come up with the answer. But that's not all — rather than just give you an answer without showing you how it arrives to that solution, you'll get detailed step-by-step explanations of how to arrive at that answer. At the moment, Photomath has full support for arithmetics, fractions, decimal numbers, linear equations, equation systems, and some functions like logarithms. While you can have Photomath solve more complex problems like integrals, trigonometry, and derivatives, these don't have support for step-by-step explanations just yet.

Why we love it

We remember how tough equations can be in school, and wish we had something like this around back then. Being able to take a photo of the equation and then have it explain how to get the answer is super helpful.

Calculate and Convert at the Same Time

If you want a simple calculator that gets the job done, but need to do some basic unit conversions too, then make sure to check out this app.

EZPZ Unit Converter

EZPZ Unit Converter

Martin Engelsgjerd

EZPZ Unit Converter consists of 17 categories that simplify the conversion of currency, temperature, length, weight, speed, area, and volume with more than 1000 different conversions and 160+ different live rate currencies.

Save your conversions that you use a lot, and add the EZPZ Saved Conversions widget for very easy access.

EZPZ Unit converter also provides fun facts involving the units used in the conversions, making the App not only very practical, but fun to use as well.

Swipe right and use the search bar to search for units/currencies instead of choosing the category and manually picking the unit. When searching for a currency in the search field it will change the left column (the from currency), and if you search again it will change the right column (the to currency).

This App is completely free.

The menus, icons, and colors that comprise the Apps’ design, allows it to be very user friendly, pleasant to look at, and easy to navigate. Enabling the user to conveniently access the conversions in the fastest possible way. Enjoy!

Graph Those Calculations

With complex equations come complicated graphs. Get the job done with this great app.

Calculator of Formulas

Calculator of Formulas

Robert Fraczkiewicz

This app is focused on calculating and graphing mathematical formulas for everyday life and work. What distinguishes it from many other RPN calculators available at the App Store? Some of them allow for formula coding, do graphs, and are free, too. Unfortunately, most of these apps feature formulas of only one variable. In most real life applications, however, mathematical formulas have multiple variables! This app does all of the above plus the following:

* Programs mathematical formulas with up to six variables.
* Is simple to use.
* Plots graphs with respect to a chosen single variable while keeping all other variables fixed.
* Plots graphs when all the variables are changing along a user-prescribed vector. This relatively new concept of "ray plotting" enables user to probe a function in n dimensions by looking at its 1-dimensional slices.
* Does graph tracing and enables graph manipulation with a simple set of intuitive touch gestures instead of button/pop up controls.
* Saves most used formulas along with detailed description for later use.
* Creates tables of calculated results that can be pasted into other applications.
* Has an exhaustive set of help files and tutorials.
