Kaer Math · Burlingame, California, United States
What it is
Kaer Math is a K–12 math learning app for Android and the web. A placement test sets a starting point, then daily practice adjusts to each learner’s per-skill hit rates. The app can recommend warmups, practice on weak skills, new topics, or mastery tests. Four worlds span grade bands, with stepping-stone lessons and a mastery test in each topic. Practice includes nine grade animals that evolve, a daily logic challenge, quests, streaks, and cosmetic Peel Deals. Parents can choose weekly email summaries and check progress in a PIN-protected dashboard without a separate parent account. Hints and tutor explanations may be generated using Anthropic Claude, which may receive problem or session content. The free plan includes all grades and topics, collections and evolutions, hints, an adaptive path, the daily challenge, and five lives per day. 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 and links to Google Play; its App Store download is marked “Coming soon.”
