## What is Calculator?

Calculator

Easily type out math with the basic and scientific calculators for quick solutions. With the Math Notes calculator, solving expressions, creating and using variables, and even plotting equations on graphs is as simple as typing or writing them out.


Basic & Scientific Calculators
Type complete expressions with parentheses, and basic and scientific operations before hitting equal for the final answer. With history, you can keep track of previous calculations, and easily copy or switch back to previous results.

Unit Conversion
Unit conversions in the basic and scientific calculators help you quickly convert between hundreds of units including length, speed, temperature, weight and more. You can even get up-to-date conversions for currencies from around the world.

Math Notes
Type math or write it out using Apple Pencil on iPad, and Math Notes will solve your expressions inline as soon as you add an equal sign. Math Notes supports all the same functions as the basic and scientific calculators, unit conversions and even math written vertically.

Variables
Create variables by typing or writing their name, an equals sign and then their value. Name them with letters or words. Tap on a variable’s value to easily adjust the value up or down. And use your variables in expressions, and even graphed equations across a Math Note.

Graphing
Type or write an equation, and with a tap you can graph it in Math Notes. Zoom, pan around, or resize your graph to get it just right. You can even add multiple equations on the same graph to see how they’re related.

### 2/5 — Too many sweats

*2026-08-24, version 2.2*

Whatever server runs this is clearly not doing good, incredibly laggy too many ads AND too many sweats??!!

### 5/5 — All right, Apple I see you

*2026-08-20, version 2.2*

This is nice I mean really nice and people are lazy when they reach you one star review, saying that they can do fractions or do other money in different countries. Also, I saw another app that is just like yours and it for iPad. It had lots of five star reviews, but it just looks like yours, but the things are darker or orange. I love this app.

### 5/5 — You should use

*2026-08-20, version 2.2*

This app is my favourite. You should use it a lot. 2 + 2 =4

### 5/5 — No mistakes yet

*2026-08-19, version 2.2*

Very happy with this app. I have used many times and I believe it to be correct 100% of the time. Has all numbers available. 10/10 will use again.

### 1/5 — for nitwits

*2026-08-19, version 2.2*

running total has less buttons to push: this is slower than it should be.

### 3/5 — Calculator

*2026-08-18, version 2.2*

Calculator

### 2/5 — Dumb calculator

*2026-08-17, version 2.2*

I did the hardest thing and. Apple get it wrong.
🤬

### 2/5 — Calculator

*2026-08-17, version 2.2*

You are not able to edit previous numbers, digits and Mathematical symbols! Previous calculates should be visible on the main screen

### 3/5 — I guess it’s OK for most applications

*2026-08-15, version 2.2*

I guess it’s OK for most applications, but it will not let you enter fractions because there is no/Mark. At least I can’t find it.

### 1/5 — Not accurate

*2026-08-14, version 2.2*

Not accurate
