Not sure if this is still an issue for those that were discussing. The only alternatives that I have found are Panther Math Paper. It takes less time to get started and seems to have more options. There are more buttons for early math including shapes and money. It also has great functions for regrouping and carrying in multiple digit addition and subtraction problems. It also seems to accommodate more advanced math. The only negatives that I have found is that saving and retrieving documents is difficult to navigate, and you can not import problems from a worksheet. Other than that, we have been really successful using the app. We are very thankful to have stumbled across it!
