This is much more complicated. Technology may add a lot, not just a tiny bit, but it has to be used in such way. While certainly apps are being created [and soon they may reach much harder topics, like indefinite integrals] the core issue is in using them - there is no point in technology alone if it is not used. It depends heavily on parents so that they can enable and encourage children to use the app but it also depends on children to use [or rather play] the app. Technology is not solution to the problem per se - Technology only enables us to solve the problem.
