What Kaer Math is
Kaer Math is a K–12 math learning app for Android and the web. It begins with a placement test, builds a personalized path, and adapts daily practice using hit rates for each skill. Recommendations may include warmups, weak-skill work, new topics, or mastery tests. Four learning worlds cover grade bands, with stepping-stone lessons and a mastery test in every topic. Gamified practice includes nine grade animals with evolutions, a daily logic challenge, quests, streaks, and cosmetic Peel Deals. Parents can receive weekly email summaries and view a PIN-protected progress dashboard without creating a separate parent account. Hints and tutor explanations may use Anthropic Claude, and problem or session content may be sent to that provider for help text. The Free plan costs nothing and includes five lives daily; Kaer Math Pro costs $2.99 a month with unlimited lives, streak freeze, heart refills, and no ads. Google Play is linked; the App Store is marked “Coming soon.”
