Spot the Dot iPad app.
Unfortunately, the article's link to the spreadsheet is broken (it's missing the "l" at the end of "html"). The correct link is: http://www.squidalicious.com/2011/01/ipad-apps-for-autism-spreadsheet-of.html
UPDATE: The link is now fixed. Hurrah!
It's a good article, worth your time. And as always, I do welcome app recommendations so we can keep that spreadsheet timely and relevant.
