Today's Free App of the Day is NeoCal Advanced Calculator
Originally $7.99

This is a very well reviewed calculator. It was the Free App of the Day previously on March 6, 2013. It's very nice. The one star reviews mainly have to do with requiring to be logged into the Amazon Appstore on non Kindles in order to use the app. It works fine on my Kindle Fire in airplane mode. I love calculator apps, as I've mentioned before. This is a nice one, and I like the different "pages" which are really sets of functions to pair with the calculator. Ever wanted to know the date 90 days from now? There's a date and time page for various date functions. On any of the pages, tap the 2nd key above the 7 on the keypad to switch to a secondary function shown in grey on the page section.

165 of 190 reviews are four stars and above.

These apps are compatible with the original Fire and with my Fire HDXs. To tell if an app works for your Fire HD or other Android device registered to your Amazon account, click on the above link and look on the right side of the web page. Amazon will tell you if it will work with your registered device.

Have fun!
