Frequently asked questions
Is Synthesis worth the higher price compared to other kids' math apps?
Its rigor and origin as a program built for a demanding user base (SpaceX employee families) suggest real quality, but at this price point it's worth weighing against free or lower-cost alternatives depending on your child's specific needs.
