Easy as ONE-TWO-THREE
This week I want to share with you two little free apps that might help people with aphasia or developmental disabilities to say, use, and write numbers.
Numwords is a free app for iPhone. You type in the digits to the top bar and the spelling of the words appears in the center of the app. For example, when you type in "723", you get "seven hundred twenty-three." The text can then be copied to the clipboard for pasting anywhere else. This app could be very useful for anyone writing checks, but may also help users to accurately say longer strings of numbers.
People with aphasia often have more difficulty reading numbers aloud than printed words, so converting numbers to words makes it easier. The app was developed by a Russian developer, so the English is a bit awkward ("specify the number of digits" means to enter the number in digits), but the spelling seems to be accurate for the main purpose of the app. Download from iTunes or the App Store for free.
Dyscalculator is another free app for iPhone by a Danish developer. Not only is it a calculator, it also pairs each digit with the written number and shows the full calculation on-screen. With the "Speak Selection" accessibility option enabled, it also allows you to hear each number spoken aloud.
Turning the app to landscape orientation gives a visual representation of the numbers and equation.
This app has two other really interesting features: number reversal and an algebra helper. Pressing the up-arrow button reveals options to switch the order of the two numbers in the equation or rearrange the digits within either number. The math function buttons can be converted to solve for an unknown: instead of +, press +? to ask "this number plus what gives the second number." There's even a "Round" button for easy rounding.
The drawback of this calculator is that it only handles two numbers at a time; no adding up lists of numbers. This app could be very useful for students struggling with math or those with dyscalculia, along with clients who have language or cognitive impairments. Download on the App Store for free.
