Right now on the iOS app store there are countless talking calculators available for purchase and even some for free. We’ve looked at Talking Calculator in the past, and it does a great job of calculating complex formulas hands-free with full VoiceOver support. For users who are blind, have low-vision, or have learning disabilities that make it difficult to visually process numbers, talking calculators can help level the playing field by giving users the ability to engage in math problems independently.
