i-Ready Personalized Instruction vs Lumastery

i-Ready Personalized Instruction has no write-up on Specifiction yet; its figures are above.

Lumastery is a homeschool web app with lessons and adaptive practice in math and reading, plus on-screen science lessons. It is designed for families managing children at different ages and learning levels. Practice difficulty responds to a child's recent answers and can return to foundational skills. A skill is marked mastered at 85% across the last 10 attempts; spaced review revisits skills over time, except arithmetic-chain skills. The Family plan allows a choice of traditional or conceptual math instruction for each child. Listed curriculum includes 238 math lessons, 157 structured reading lessons, and 117 on-screen K–8 science lessons. Science is not lab work; literature has three pilot chapters, writing assignments are a parent-graded pilot, and world languages are not offered. The free plan is described as one child and one daily session. Family is listed at $19.99 a month or $199 per year, with up to four children and unlimited sessions, but checkout is not live and the plan cannot be bought or trialed. The public beta has ended, new registrations are closed, and the app is unavailable to families during its wind-down.
