Bottom Line: Kindergarten Readiness promises to help prepare kids for kindergarten with early math, early literacy, cognitive development, self-care/motor skills and communication/social skills in one app. Unfortunately that's a tad misleading, since many of the skills are merely checklists with tips for parents to help kids offline. That being said, the in-app games that are provided are a good first step toward fostering a love of learning.
Bottom Line: Exam Elf is like boot camp for teaching fourth, fifth and sixth graders standardized testing skills for Common Core-aligned mathmatics. Make no mistake, this app exists to teach testing skills, and it notes shortcomings in detailed reports. Although it gives corrected answers, there are no explanations provided to students. Users who need to get more comfortable with test taking will benefit from the large volume of questions they must answer to progress in the app.
