iLearn II, a new report from the Joan Ganz Cooney Center at Sesame Workshop, looks at 196 recent top-selling iPad and iPhone apps from the education category. Among its findings: over 80% target kids from preschool to middle school, with 60% of the top 25 targeting toddler and preschool children. As this suggests, "early learning" apps are the most popular, followed by math--but literacy apps are "surprisingly sparse." The average price of these apps has risen by about $1 from a similar study in 2009, but the majority are still priced moderately at $0.99 or $1.99. Lots of useful tidbits--and perhaps a handy reference for your market research.
