- improved button design

- back button and Action Bar works according to guidelines

Changes in version 1.1.1

- Fixed linkage error

Changes in version 1.1.0

Q. How do I view the Step-by-Step screen for a problem?

A. First enter the problem into the calculator and hit enter to see the result. Then click on the result. Make sure you are clicking on the result and not its input, as clicking on its input will paste the input into the current entry field. Also, Step-by-Step must be enabled in the settings when the result is calculated. By default Step-by-Step is enabled.

If you are not completely satisfied with your purchase and you email me at support@mathally.com within 14 days of your purchase, I will give you a refund. Please include your order number in the email. (Google play only gives you 15 minutes to automatically get a refund, I think this is too short). You can only request a refund once.

If you find any bugs or have questions, please email me.

Explanation of permissions:

Storage - Needed for app to be able to read/write to external storage. This allows users to transfer custom keyboards between devices.

FAQ’s

Q. Is there are tutorial anywhere explaining how to use the graphing calculator?

A. There are three into tutorials in the app for the calculator, graph equations, and graph screens. Additional tutorials can be found on our website http://www.mathally.com/

Q. How do I get to the keys for pi, e, solve, etc?

A. There are four keyboard pages. Each swipe direction across the keyboard moves you to a different page. The default page is the swipe down page. To get to the page with trig functions, swipe left. To get to the matrix keys, swipe up. To get to the last page, swipe right. No matter what page you are on, the swipe direction to move to a specific page is always the same.

Q. What do you have planned for future releases?

A. You can keep up to date on the latest news on our blog at http://mathally.blogspot.com/ . This news will include what is coming up in future releases. Also feel free to leave comments and let me know what you think!
