Finally, our flagship Next-Generation Interactive Textbook is released! Check it out if you haven't already here. You will be guided magically to the appropriate App Store if you are
It wasn't easy! This content is made up of 14 topics and a total of 250 lessons. At 4 minutes per lesson, that's a 1000 minutes or 17 hours of continuous instruction. No Algebra electronic course we know of covers so much.
We first started developing this course over three years ago. At the time, our technology and standards were not mature yet (and those of you who have been with us that long, will notice that the voice is much better now). It takes a lot to get to this point of maturity.
We launched our free version in 2011 to see if it gets enough interest, and our website got overwhelmed! We upgraded our servers, fixed up the content and technology, we even launched the apps on iPad / iPhone, Android, and Kindle. In many app stores, we are the #1 Algebra App.
Now fast-forward to end of 2012, we now have improved our technology substantially, learned from our users and teachers, and added many of the missing lessons. The App is now updated on iOS and Android with In-App Purchase per topic (launch price at $0.99 per topic).
Now we have to tell the whole world that it's ready. Many schools are starting to use it in the next school year, this will get more people to hear about it. We will reach out to more educational institutions and key thought leaders to share with them the good news and get their feedback.
