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
- Swipe my memory buttons aside when you need advanced math.
- My percentage key shows exactly what it did, so you're not left confused
- 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.

4.0 out of 5 stars No internet needed October 19, 2013
Verified Purchase
I don't write a lot of reviews but just had to set the record straight. This app is basic-so if you don't want basic fine get something else but don't rate Calc Plus low b/c of that. Secondly, the internet is NOT necessary to run the app. The internet is only needed for the first time. I opened the app and used it one time with internet. Then turned my connection off and the app still worked just fine. Those who don't bother to truly check out an app shouldn't post a review until they do b/c it's nasty to say false things. Have a happy day!

5.0 out of 5 stars Excellent Basic Calculator March 18, 2012
Verified Purchase
Calculator Plus is an excellent basic calculator with one critical characteristic I was looking for. It keeps the last value shown on the display even after turning off the Kindle Fire. I'd been looking for a calculator that met that requirement.

Secondly, when I requested that the calculator rotate 180 degrees with the rotation of the Fire, their development team added that feature within a week or so. I couldn't believe their quick response.

I highly recommend this calculator for anyone looking for a great calculator to use on the Kindle Fire.

2.0 out of 5 stars does not handle order of operations October 19, 2013
Verified Purchase
Even simple math has to consider the order of operations before you hit =.
The equation 2+2+3x5= provides 35
The correct answer is 19.
You always / x - + even without ( ).
I get that it runs like an adding machine but it does not run like a calculator.
Nice thought but can't keep it.

3.0 out of 5 stars Calculator Minus October 19, 2013
By Deeje
Verified Purchase
The stock Android calculator on my Galaxy has about twice the features that this one has. Calculator Plus is missing parentheses, which is a big deal to me, and a multitude of scientific features that the stock calculator has. CP seems to boast its percentage button, but the stock one has that button as well, and it works better. The design is a little dated, though I think iPhone users would probably dig it. All around not a bad piece of software, but it just can't compare to what Android already has built in.

1.0 out of 5 stars Doesn't do precidence. February 7, 2013
Verified Purchase
I was checking some equations, and the math on this does not take precedence into account.

2+4*6 will calculate as (2+4)*6

A calculator that doesn't follw the order of operations as taught in middle school is not not worth much. It doesn't help most people find the correct result to a series of calculations. Ask any math teacher what good is such a calculator---not worth the effort to use one.

1.0 out of 5 stars Needs Internet??!! October 19, 2013
Verified Purchase
The free version is better because it does not need the Internet! I'm glad it was the FAOTD! Why does the paid one need intenet? Who needs internet for a basic calculator? I am deleting it!

1.0 out of 5 stars WORTHLESS September 27, 2013
Verified Purchase
I couldn't have been more pleased and impressed when I purchased this application, BUT when I used it the first time for real later on, it wouldn't work unless I was connected to the Internet.

For security and battery life, I keep my Kindle Fire disconnected from the Internet, which makes this application WORTHLESS.
