About Talking Scientific Calculator
A comprehensively featured calculator that has become a favorite among adults and high school students around the world. Designed for a wide range of users, this calculator has large colorful buttons, optional high contrast, full VoiceOver support, and unique to this calculator; the option to use speech for answers, buttons names and formulas!
** Regularly featured on "What's Hot" - Utilities
Video demo available from the support link.
Features include:
--------------------------
- Can read answers, entered numbers and formulas aloud.
1,234.56 is spoken as "One thousand, two hundred thirty four point five six" when US pronunciation style selected. UK and German styles also available.
2 + 3 x 5^2 is spoken as "two plus three multiply five squared."
- Built in recording studio and script. Requires only 5 minutes to record a new voice. Recordings can be transferred between devices using Bluetooth.
- Two entry modes, Standard and Formula. Standard mode emulates traditional calculators. Formula mode takes care of the order of operations for you. You enter a mathematical expression, complete with operators and parentheses (brackets), tap the = button, and the expression is evaluated.
- The entire app's feature set is accessible to VoiceOver users (using standard or touch typing input styles) and Switch Control users.
- Unique to this app is an Enhanced VoiceOver Speech mode that pronounces large numbers and formula with natural language rather than one digit at a time.
- Supports entry and display of Braille on supported devices (thanks to assistance from the Washington State School for the Blind.)
- Numeric formatting of results: Max fraction digits (default), fixed fraction digits (useful for currency calculations), and max significant digits (useful for science and engineering lab work), plus international formatting.
- Trigonometric, hyperbolic, logarithmic, permutations, combinations, factorial, powers, roots, percent and bit-wise operations, conversion between hexadecimal and decimal, random numbers.
- Full support for fractions (simple and mixed), conversion to and from decimal, fraction reduction, and use of fractions with all operators.
- Easy access to basic calculator functions, for those who rarely use scientific operations.
- Paper log feature, designed particularly for classroom use. Calculations can be recorded with a timestamp to be viewed and emailed.
- iPads get a user interface designed to make use of the large screen area. iPhones and iPod Touches get a user interface designed for the smaller screen. This includes large, easy to read scientific buttons, accessed on a scrolling panel. All the features of the iPad version are included in the smaller design.

Customizable for each level of vision:
--------------------------------------------
Normal to low vision: Large, clear buttons with optional speech.
Low vision: High contrast display mode, with optional speech.
No vision / blind: VoiceOver reads the button names before they are activated and also calculation results. Entry and display on refreshable Braille devices.
Switch control accessible. Split-view and Slide-over supported.
Why record new voices?
--------------------------------------------
Having your iPad, iPhone or iPod Touch talk with your own voice, or that of a friend or tutor will make the calculator sound more natural to you. The calculator will speak with the accent you are used to hearing.
How good is the sound quality of recorded voices?
Excellent: The microphone in your iPad / iPhone or iPod Touch is of very good quality, and this calculator performs digital signal processing to ensure the audio level is consistent across all recorded words.

NEW TO 5.6:
- Improved VoiceOver for calculations, especially for iPhone/iPod users.
- Improved VoiceOver for the recording studio, especially for iPad users.
- Fixed a rare bug that affected the inbuilt voice after switching to other audio apps.
NEW TO 5.5:
Changes to the % button, so that it now recognises when it is used in the context of an addition or subtraction.
Eg 1. '200 + 5%' is shorthand for '200 plus 5% of 200' and is therefore calculated by first determining 5% of 200, then adding 200. The result is 210.
Eg 2. '200 - 5%' is shorthand for '200 subtract 5% of 200' and is therefore calculated by first determining 5% of 200, then subtracting from 200. The result is 190.
