What Kaer Math is
Kaer Math is a K–12 math learning app for Android and the web. A placement test sets a personalized learning path, and daily practice adapts using each skill’s hit rate. The app can recommend warmups, practice for weaker skills, new topics, or mastery tests. Four learning worlds cover grade bands, with stepping-stone lessons and a mastery test in every topic. Practice includes nine grade animals that evolve, plus a daily logic challenge, quests, streaks, and cosmetic rewards called Peel Deals. Parents can opt into weekly email summaries and see progress in a PIN-protected dashboard without a separate parent account. Hints and tutor explanations may use Anthropic Claude, and problem or session content may be sent to the provider to generate help text. The free plan includes every grade and topic, five lives per day, hints, and the daily challenge. Kaer Math Pro costs $2.99 a month and adds unlimited lives, streak freeze, heart refills, and no ads. The website offers free lessons for grades K–8; its App Store download is marked “Coming soon.”
