This is an accessible calculator that speaks the names of buttons as they are tapped and reads out the numeric answers. The speaking voice doesn't sound like a computer. It is very conversational, which makes it fun to use. In fact it sounds just like me, because I followed the script and recorded my own voice directly into my iPhone. I did all this in around five minutes, using VoiceOver to guide me.
For those with sight, I'm told it's colourful and easy to read with a large font. There is also a high contrast mode.
Instead of using VoiceOver for speaking the numbers, it uses its built-in recorded voice (which is ok), or your own recorded voice (which is awesome.) When recording your own voice, you have to speak the numbers 1 through 19, then 20, 30, 40 to 90, then hundred, thousand, million and so on. The calculator then strings these recordings togther to read out the numbers. The result is far better than the the iPhone's built in calculator which tries to use VoiceOver to read the numbers, and often gets it wrong.
Having said that, the integration with VoiceOver for finding buttons to tap works very well. I was able to use all calculator functions, navigate the information panel, have the help read to me, and use the "recording studio."
This is a basic calculator, but it has some advanced features like parantheses buttons, roots, squares, cubes and memory functions. In the version 2.0 update, you can turn these off and instead have even larger simple buttons, which works very well with young children. (I have friends using it this way.) It only costs $0.99 my currency, so I presume it's the lowest price-tier in all currencies.
If you search for 'accessible calculator' on the app store, there are only two results: This calculator, and a $5.49 priced version called the Talking Scientific Calculator, which apparently is the 'big brother' to this calculator I'm reviewing. Highly recommended.
