Skills mastered by students today
The method
Precision, not repetition
01
Diagnose
A short warm-up maps exactly where your student sits on each skill — no guessing, no wasted time.
02
Adapt
The engine adjusts difficulty question-by-question. Too easy? Harder. Struggling? Scaffolded support kicks in.
03
Master
A skill is only marked mastered when the student proves it consistently — not once by luck.
What families say
Loved by parents, students, and teachers
“My daughter went from dreading math to asking to do 'just one more question' before bed. The streak feature actually works on a 9-year-old.”
“I can finally see exactly which skills my class is struggling with, in real time. Saves me at least an hour of grading every week.”
“I like that I can pick up where I left off. And when I got my first 10-streak the confetti was awesome.”
