Product Description

*** One of USA TODAY's "25 essential Kindle Fire apps" ***

I'm Calculator Plus - the perfect calculator for Kindle Fire. I'm easy to use and beautifully designed to do things better than your handheld calculator ever did.

I love saving you time and effort. I remember everything you calculate, and let you review it anytime, making me perfect for adding up receipts, balancing checkbooks, or even calculating taxes. And if you quit the calculator and go do something else, it's all still here when you come back. You'll never need to type the same calculation twice again.

I'm attractive and effective and I make great use of that big, beautiful Kindle Fire display:

- You'll never forget where you are in a calculation - I show you exactly what's happening at all times
- I remember everything, so you can take a break, then come back later and pick up where you left off
- I show your calculations in clear, elegant type that's easy to read, with commas just where they should be
- You can use backspace anytime to correct a simple mistake, instead of starting over
- Use memory to keep a running total you can actually see
- My percentage key shows exactly what it did, so you're not left confused
- NEW! Swipe memory keys aside for advanced math functions!
- My intuitive, lovable design makes it simple to do everyday calculations on your Kindle Fire

Let Calculator Plus and your Kindle Fire finally put that handheld calculator to rest.

This version of Calculator Plus is ad supported. An ad-free version is also available.

5.0 out of 5 stars A simple calculator app that is designed well! May 30, 2012
Verified Purchase
You might ask why someone develops a simple calculator app for the Kindle Fire. The answer is to do it right! I have reviewed and looked at many calculator apps for the Kindle Fire and this is by far the best of what I have seen so far.

Here is what I like about it:

* The user graphics interface is just sharply designed and it looks professionally done. The brushed texture of the case and the color of the buttons are great.
* The buttons are large and easy to touch and read. Some apps I have used the buttons are so small that you literally touch two at a time.
* It uses the full screen size of the Kindle Fire to give you a nice sized calculator view
* The numbers in the result display are large and easy to read.
* The display provides you with the numbers and action you used in your last calculation.
What I don't like:
* The number transaction bar shows the data in light grey. If you are going to do it then make it darker and easy to read.
* There are ads as this is a free version of the product. The ads show up in a thin bar at the top of the calculator and do not distract from the product. I like that they are on the top so you don't accidently touch them while holding your Kindle Fire. I don't like ads but the calculator design is so good I'll keep it.

I don't know what the "Plus" is for in the name but this is a nice app that is attractive and easy to use. It is by far the best simple calculator design I have seen!

"Calculator Plus" takes full advantage of the Kindle Fire's large screen to present a very basic, but perfectly functional desktop style calculator. I have several calculator apps on my Kindle Fire since my kids like to use it for their homework, but those tend to be much more complicated scientific function applications. This app only provides the basic (+), (-), (*), (/), and (%), along with a handy backspace key. I also like that it displays all of the entries as you go, which is helpful to keep track of list items.

The interface is intuitive and as basic as it gets with large friendly buttons and a clear, easy to read display. It is ad supported, but they are very unobtrusive and just about impossible to accidentally hit while using the calculator functions.

This is a good free app that works exactly as it should!

Highly Recommended!

5.0 out of 5 stars Perfect 'plain' calculator (for Kindle Fire only) May 27, 2012
Verified Purchase
This is a VERY nice implementation of a plain 'desk calculator'. Besides the 4 basic operations it comes with the 'percent' key, the traditional calculator memory keys, and a backspace function, all on a nice brushed metal finish that looks good on the Kindle Fire screen.

I am not sure what the 'plus' in the product's name stands for... it could be the backspace or maybe it displaying the last operation right underneath the answer but that's not important. It's a great, plain-vanilla calculator that works well and looks good on the Fire. And, yes, like many 'free' products it does come with ads but they are on a small, narrow band at the top of the screen and easy to ignore.
