Does anyone have any experience with programs having similar functionality to IXL, but possibly more engaging for students?  
Needs : Targeted Math drills with teacher dashboard functionality.  
Wish List : Engaging for students and less expensive than IXL

We're an iPad school, so would have to work on iOS or have an App.  

Your experience can help me to narrow the research.
Thanks, in advance, for any information you can provide.
