About this app


A simple, beautiful calculator but with added functionality such as skins and layouts. It is designed to replace the rather lame stock calculator with a calculator that looks great while retaining ease of use and intuitive design. Calculator is designed to meet all of your calculating needs!

***Calculator Features***
*Simple, accurate calculator: Leave the calculator in portrait view to see just a simple calculator, or turn the calculator on its side to reveal a scientific calculator

*Calculator Skins: Calculator v.3.0 now supports changing of skins to change the look and feel of the calculator. Choose between and array of different skins to match your favorite phone OS. Also if there is a certain skin you would like to see made for you, don't hesitate to send an email!

*Different calculator layouts: Choose between 3 different calculator layouts. 1) Default Layout for a standard 10-key calculator in portrait mode and scientific calculator in landscape. 2) Business Layout adds a '%' key in portrait mode and a '00' key. 3) Simple Layout keeps the 10-key calculator in both portrait and landscape mode when all you need is a simple calculator.

*Memory Buttons- Fully functional 'M+', 'M-', 'MR' and 'MC' calculator buttons. Calculator will remember the value stored in it even if you leave the app.

*Landscape calculator: Turn your phone on its side to reveal a scientific calculator with advanced functions like square root, exponents, factorials and more.

*Trig calculator: The landscape calculator even features full support for trigonometric functions. Calculator can take Sin, Cos, Tan, inverse trig, and hyperbolic functions and can calculate in both Radian and degree mode. Great for use in algrebra and other math classes.

*Calculator looks great from the smallest to the largest screens as well as low and high density screens. Calculator also works on the Galaxy Tab!

*App2SD- You can install Calculator to your SD card if using Android 2.2+

Works very well on my Epic 4G Touch, Note 2 and Note 3. Every time I get a new phone I download this app. Has basic features in portrait mode including % and change sign keys, and advanced features in landscape. Nice keyboard and color schemes layouts. It has an odd clear entry function - one digit at a time. Just tap the current entry and the last digit is deleted. Need to continue to tap to delete additional digits or the entire entry. Handy if the last digit was mistyped and that is the only digit you want to clear. I did find one bug: if you store data in memory it highlights the memory recall key ("mr") which is good, but if you exit the app by using the Back Key and then later open the app, the data is still in memory but the mr key is no longer lit. This can lead to errors in data being added to an old piece of stored data. If you exit the app using the Home Key the mr key will still be highlighted when you restart the app. Minor issue.

Purchased the Calculator and could not change the skins or implement any options. Phones with capacitive navigation buttons can not access the menu. Support has not been available so save your money or purchase calculator plus as it is still updated and is working on capacitive navigation button phones. Listed in Google Play as compatible with my phone... not so! 1 star because there is absolutely no support response from the developer to resolve these issues.

Coming from an iPhone I really missed the calculator. The paid version of this app not only matches that app but exceeds it in my opinion. This app allows you to to change the themes and look of the calculator which actually improves on the original design. Do your self a favour and get the paid version. Its only 65p and its well worth it. The free version does not have scientific settings.

What's new

Version 3.2.1 (Minor Release)

- Removed Permission request for Internet Access (Sorry I thought I needed this one. Wasn't trying to do anything shady)

- Minor UI changes in the menus

- Brand New! Added 'nCr' function in landscape mode. Hit the 'Alt' button when in landscape mode to reveal this new function.
