LogicQuest
Master the building blocks of clear thinking — identify logical fallacies, construct truth tables, map arguments, and crack syllogistic puzzles through detective investigations and debate challenges. Ages 10-14.
Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, praises, and patiently scaffolds learning. On-device AI personalizes the mentor's responses to your kid's progress — never connecting to a server, never collecting data.
