The same audited engine schools license — for your student
Every problem is generated fresh on the device, resolves to an exact answer, and is machine-checked. No wrong answer keys, no calculator decimals.
Seven math tracks
Algebra I & II / Precalculus, Geometry, and SAT / SSAT / ISEE / HSPT math — for summer refresh, the school year, and entrance exams.
Named mistakes
Every wrong choice maps to one specific error — "flipped the inequality," "distributed only the first term" — so you learn the why.
Timed practice tests
A full placement-style test with a predicted score, plus per-exam sittings that mirror the real formats.
Mastery & study plan
Tracks what's truly mastered, resurfaces topics before you'd forget them, and builds a personalized plan around your gaps.
AI tutor
Step-by-step walkthroughs, fresh worked examples, and "how to think about it" coaching. Homework Help — paste your own problem — comes with AI Tutor+. Parents can turn AI off.
Private by design
No account, no login, no personal information collected. The engine runs offline on your device. Privacy Policy →
Real screens, real feedback
Straight from the app — the dashboard, a problem mid-solve with the box-method scaffold, and the named-mistake feedback that teaches the why.
