World premiere

Coming September 13th 12PM PST

We are sorry for delaying the release of Kaer Math, with this additional time, we will continue to improve the game for your best experience. Stay tuned for more updates.

K–12 math learning app

Math practice that finds the next right step.

Kaer Math builds a personalized world path from a placement test, then adapts every day — warmups, weak-skill fixes, new topics, or mastery when they’re ready. Kaer, a sarcastic-but-warm monkey in a graduation cap, keeps them moving.

Free for every grade and topic. Pro is optional.

Biggest flex · No signup

Try a lesson from the app.

Pick a grade. We spin up a random topic and a random lesson — real Kaer Math questions, hearts, hints, and Kaer. Two minutes. Zero download.

How it works

Placement → path → practice → evolution

Four steps. Tap a phone to expand it, or More info for the details.

  1. 1

    Placement test

    A short adaptive check finds the right starting grade band — not a one-size “start at page 1.”

    Tap phone to expand
  2. 2

    Personalized world path

    Four worlds — Explorer, Adventurer, Champion, Master — each covering a grade band. Inside every topic: stepping-stone lessons plus a mastery test.

  3. 3

    Daily practice that adapts

    The engine watches per-skill hit rates and recommends what to do next: warmup, fix a weak skill, push a new topic, or sit a mastery test.

    Evolutions & collection

    Nine grade animals, each with its own evolution cinematic. Progress feels like collecting — because it is.

Inside the app

Built around how kids actually learn math

Tap recommendation chips, animals, or phones for more.

Adaptive engine — not a static checklist

Behind the path, Kaer Math tracks hit rates per skill. Recommendations shift: warmups when they’re rusty, targeted fixes when a skill is weak, new topics when they’re ready, mastery tests when confidence is earned.

Kaer thinking

World path & stepping stones

Explorer → Adventurer → Champion → Master. Each world is a grade band. Every topic is a trail of stones ending in a mastery check — so kids always see where they are and what’s next.

Evolutions & collection

Nine grade companions, each with staged evolutions and a cinematic payoff. The collection isn’t fluff — it’s the scoreboard kids care about. Tap any animal.

Daily challenge, quests, streaks & Peel Deals

A daily logic puzzle, quests to clear, streaks with freeze items when life happens, and Peel Deals for cosmetics. Structure for the day — rewards for showing up.

FAQ

Straight answers

Is Kaer Math free?

Yes. Every grade, every topic, and every evolution is available on the free tier, with 5 lives per day. Kaer Math Pro ($2.99/month or $19.99/year) adds unlimited lives, streak freeze, heart refills, and no ads.

What ages / grades is it for?

K–12. Four worlds (Explorer, Adventurer, Champion, Master) cover grade bands. A placement test picks a starting point; the adaptive engine keeps adjusting. You can try a free lesson for grades K–8 right on this site.

Do parents need a separate account?

No. Optional weekly report emails go to an address you add on the kid’s profile. The in-app parent dashboard is PIN-gated on the same device.

How do weekly parent emails work?

If you add a parent email and leave weekly updates on, you’ll get a summary of streak, skills practiced, and what to work on next. You can turn emails off in Settings or unsubscribe from any report.
