With all due respect, the Shema should be said clearly, not rushed, not with words blending together and all letters pronounced. (Do it over?)
The "girls" version is a little better, but again, it is very bad to learn improper pronunciation first - only to need to be re-taught with proper pronunciation later in addition to breaking the habits of saying words incorrectly.
Perhaps utilize children ( or grown ups ) that understand how to halachically say the Shema properly; especially since this is the only part of Jewish liturgy that absolutely must be said in Hebrew (first two lines). Ask any scholar or rabbi about this.
Better yet, have a rabbi or Torah scholar check the recording before releasing any updated soundtrack.
I hope this doesnt offend the kids or the parents of the kids, but this is serious stuff.
Nice to see the option to skip the brushing teeth and turning off the light etc. could make it more user friendly after the initial use of the app for continued use, since if a child will be using this night after night for a while, it may become tedious to get right to the business of saying Shema with needing to go through the other "cute" clutter.
