One account from letter sounds to calculus
The early-years app does its job and then, somewhere around eight, your child walks out of it and you are shopping again. Koydo is designed not to be replaced: the same account, the same login and the same history carry a learner from tracing letters through fractions, essays, chemistry and calculus.

Ages 3 through college
Phonics, then reading comprehension, then literary analysis — one continuous sequence, with your child's level and preferences travelling the whole way.
A tutor pitched to the age in front of it
Picture-and-story for a six-year-old, a worked proof for a sixteen-year-old. Same product, included on every paid plan, different voice.
Still playful when the maths gets hard
Games, labs and interactive stories continue right up the age range instead of being switched off the moment real school work starts.
Up to 6 learner profiles on one plan
Which matters most in exactly the household where one child is four and the other is fourteen — separate progress, separate pace, one subscription.
The path to exams already exists
SAT, PSAT and AP preparation, plus transcripts and college-readiness tools, are waiting on the same account when your child eventually needs them.
50+ languages, and the interface too
Study any of 50+ languages, and switch the whole platform into the language you speak at home so the youngest learner is not blocked by English.

Frequently asked questions
Is Koydo too advanced for a three-year-old?
No — the early years are a proper part of the product. Instructions are spoken, targets are large and nothing requires reading, and the same account is still the right one a decade later.
My eight-year-old is bored with their current app. Where do they start?
Wherever they actually are, which Koydo works out from the first few sessions rather than from their school year. Bored usually means under-pitched, and adaptive placement fixes that quickly.
Do we lose progress if we switch?
Progress from another product does not transfer, but nothing is lost in practice: Koydo re-places a learner from their own answers within a few sessions rather than asking you to declare a level.
What can I see as a parent?
The Family Home shows subjects, recent sessions and where things are going slowly, for every seat on the plan. A Family plan carries 6 learner profiles.
