About Calculator +

Calculator+ app is one of the better full-featured calculators, offering several different modes and calculator styles, supporting scientific, handwriting, polynomial, linear, graphing, and currency. 

Teacher Review

Calculator+ (free, $5 to unlock all modes) keeps its flexibility by putting the main portion of the keyboard—with the numbers and enter commands—in one section while including a scrollable bar for the function-specific keys. This keeps the design consistent yet allows you to quickly find what is needed for an equation.

The handwriting calculator takes a little bit of work. Calculator+ makes you go through the exercise of writing out what the app confusingly calls "shapes"—each of the numbers and math symbols—in order for the app to recognize your handwriting.

However, once this is done you can write math equations with a stylus or finger, which is rather convenient. It also may help younger students who are just getting started with build some confidence with numbers.

Another bonus of unlocking the full version is the customization, which lets you choose from several different themes to change up the look of the calculator.
