It is with a heavy heart that we had to pull the plug on “Step2Step Physics – Mechanics” for the iPad. Step2Step Physics was our flagship product since 2012, and we loved using it in the classroom with our own students. Unfortunately, iOS 9 made some changes that resulted in over 3000 errors and warnings in the source code. The app became almost completely nonfunctional with the iOS update. We tried to fix the code in version 1.6, but found that our best efforts weren’t enough to make the app usable again. We then made the decision to pull Step2Step from the iTunes App Store.
Who knows. Someday we might try to rebuild Step2Step from scratch. For now we are busy creating new HTML5 simulations on www.simbucket.com and refining our new free website, www.quizevolved.com. Stay tuned for more on those!
