My students were instructed to save this link to their iPad so they could immediately go to the site every morning. They start with the Grade 5 problem and work their way up to higher grade levels. Students work on the problems in their notebook. Once they figure out the answer, they select it on the iPad and they are immediately told whether or not their answer was correct.
I have not tried either of these yet, but there are additional options for a paid app and student login. I haven't tried them because the current setup works perfectly for my classroom's purposes.
