The measurement
Anyone can show a chart that goes up. Ours is worth trusting for one simple reason: we test with words your child has never practiced. Only those words can plant a flower.
Watch it happen
A skill becomes a flower in the garden only after it proves itself on separate days. Press play and watch one earn its place.

What you just watchedTen new words, three separate days. One good afternoon never plants anything.
Why it mattersWhen Lillory says mastered, it proved itself three times. You can repeat that to a teacher or a doctor.
shipshopshed
Words practiced together every session. They show effort, and effort matters. They cannot prove reading, because a good memory grows them just as well.
Shows practice.

Brand-new words, never practiced, never seen. When a child reads one right at first meeting, only real reading can explain it.
Proves reading.
Lillory counts only the wild plot. Each wild word counts once, on first meeting, mixed invisibly into ordinary play, and free to miss. Why that distinction matters when you choose a reading app.
No grade equivalent, no percentile, no single number attached to a child's name.
No outcome study exists yet, so no outcome sentence exists here. When evidence comes it will be external and shown whole.
Skills are learned separately and reported separately. An average is where the important gap hides.
An automated test keeps every pressure mechanic off a child's screen on every build, and bans the words proven, validated and guaranteed from this website.
