## What is CalcBuddy Calculator?

CalcBuddy is a lovely calculator for all situations!

If you quickly need to sum up numbers, you will like the fact that it calculates the sum immediately. There is no need to click any =. You can also see the entire expression, and add or remove from it, and CalcBuddy obediently recalculates on every change.

CalcBuddy is also very potent if you need to do advanced calculations. With all the important scientific function, such as sine and its cousines (sorry:), as well as a robust set of mathematical, physical and chemical constants, CalcBuddy can always express the answer you’re looking for.

Another thing we really like with CalcBuddy is that it stores all your calculations. Whenever you want, you can read through and return to any of your previous expressions. And if you want, you can let the calculation history be stored in iCloud. Then it will be shared and synced between all your iOS devices.

In CalcBuddy we have also included a gorgeous set of themes. So head to the settings tab, swipe the theme picker, and see as the interface is redrawn. We’re sure you’ll find the right theme just for you.

In addition, we put in a bunch of tricks and shortcuts to streamline your CalcBuddy experience even more. But let’s not be overly wordy here, instead we'd advice you all to read through the About page, where all tricks are listed.

And to those of you into specs, here are some:

* Instant as-you-type calculation

* Radians or Degrees

### 3/5 — Can't use fractions

*2013-09-24*

The only reason I bought this was because of the ability to create a fraction, like pictured. But whenever I try, The button changes to prim. I don't know what that means and just want a fraction bar!!

Hello!

Thanks for using CalcBuddy!

In this major update we have added a Today widget. That means you can now pull down notification center, and get immediate access to a lightweight version of CalcBuddy! And even though it’s lightweight, it still delivers the realtime calculation that you have to come to expect!

Other good news are:
The calculation history now shows the entire expression no matter how long it is.
There is a new theme in town. We call it Aurora. And just like the beautiful natural phenomenon, the Aurora theme appears different every time you select it.
Better compatibility with iPhone 6 and iPhone 6 plus.
Animation fine-tuning in the iPad version.

### 3.0.1 — 2013-10-17

Minor bug fixes

### 3.0 — 2013-06-02

Hello again! We're thrilled to bring you another update of our calculator. We've added some quite nice features!

* Multi-line text input.
* Introducing smart input, cursor insertion, and delete. You'll se what that means when you start using it...
* Drag and form the power-button to 2 or 3 to get those neat ² and ³.
* Prime factorize your answer, if it as an integer. The previous frac button has transformed to a frac/prime button which changes mode depending on the answer.
* Drag from a constant to the answer. Then you will get the answer expressed in terms of the constant. Then you can go frac. So 0.7853… > 0.25π > 1/4π.
* E-mail your history log (not compatible with previous history).
* iCloud synchronization of settings and history in case you use CalcBuddy on both your iPad and iPhone.
* Landscape mode for iPad.
* Swipe button panel on iPad to reveal the other panels.

…And… we also added another shiny new theme as in-app-purchase

Happy counting!

ApplicVision's CalcBuddy crew
