I had started working on a port of this app over a year ago, but got distracted and never finished, but I had a customer email me begging for an Apple version as soon as possible. I hadn't got as far along on it as I had hoped, but I did have enough time to get it in working order and release it. I also added some cool new features (that will be included in the Android versions as well) including a new animation that is displayed when the correct answer is tapped.
The other main new feature is one that I find very intriguing. I came across a website of a person who had created a free font called OpenDyslexic that has been found to be easier to read by some people who have dyslexia. I figured it would be a good option for a Learn to Read app and I am interested to hear if any children do benefit from the different font.
