This calculator stands out as a versatile tool, highly regarded by both adults and high school students globally. Its design caters to a diverse user base, incorporating large, colorful buttons and multiple accessibility features, including optional high contrast and complete VoiceOver support. A notable highlight is its ability to utilize speech for conveying answers, naming buttons, and narrating formulas.

Featured regularly in the "What's Hot" category within Utilities, it showcases a comprehensive array of features:

• All functionalities are accessible to VoiceOver users employing standard or touch typing methods, as well as switch control users.
• A distinctive Enhanced VoiceOver Speech mode articulates large numbers and formulas in natural language instead of digit-by-digit pronunciation.
• Support for Braille entry and display is available on compatible devices, facilitated by collaboration with the Washington State School for the Blind.
• Numeric formatting options include maximum fraction digits (default), fixed fraction digits for currency calculations, maximum significant digits for scientific work, along with international formatting capabilities.
• Advanced mathematical functions encompass trigonometric, hyperbolic, logarithmic functions, permutations, combinations, factorials, powers, roots, percentages, bit-wise operations, and conversions between hexadecimal and decimal systems.
• Full support for fractions—both simple and mixed—is integrated alongside conversion to decimal and fraction reduction processes utilizing all operators.
• The calculator also offers easy access to basic functions for users who infrequently engage with scientific calculations.
• A paper log feature facilitates classroom use by allowing users to record calculations with timestamps for later viewing or emailing.
• The interface adapts to iPads by optimizing the design for larger screens while maintaining functionality on iPhones and iPod Touches through a simplified layout that includes easy-to-read scientific buttons on a scrolling panel.

For users seeking statistical functionality, the companion Talking Statistics Calculator is available on the App Store.

Customization options cater to varying levels of vision:

• Normal to low vision: Features large, clear buttons with optional speech assistance.
• Low vision: Offers a high contrast display mode paired with optional speech support.
• No vision / blind: Provides VoiceOver support that reads button names upon activation and delivers calculation results. Additionally, it supports entry and display on refreshable Braille devices.

The calculator is also switch control accessible and compatible with split-view and slide-over functionalities.

Recording new voices personalizes the experience; users can select their own voice or that of a friend or tutor, creating a more familiar ambiance during use. The sound quality of these recorded voices is commendable—the built-in microphone of mobile devices offers robust audio quality combined with digital signal processing to ensure consistent sound levels across recorded words.
