The XYeed story · 80 seconds

Every kid has an athlete inside

Teams pick the fastest-grown kids — the ones still growing get overlooked. XYeed fixes that: because every child grows at their own pace, we adjust the numbers to match.

How it works

From first measurement
to a weekly training habit

No lab, no coach required. Fifteen minutes at home tells you exactly where your child stands — and what to do next.

1

Assess

Guided at-home tests with video demonstrations — sprint, jump, balance, motor skills. Tick what you see; the engine scores it against age-group benchmarks instantly.

2

Train

Every week, AI builds short missions from your child's weakest pillars. 15-minute sessions, household items, parent-and-kid friendly — plus a Sunday family challenge.

3

Progress

Percentiles update after every measurement. Every child grows at their own pace — bio-banding adjusts the numbers to match, so progress is judged fairly whenever the growth spurt arrives. XP keeps kids coming back.

Why parents choose XYeed

Built for developing bodies,
not miniature adults

⚖️

Bio-banded percentiles

Using the Khamis-Roche maturity estimate (parents' + child's heights), every child is benchmarked against their true developmental peers — whether they grew early or are still growing.

🧠

AI scouting reports

Plain-language insight after every block: what's improving, what needs attention, and the one thing to work on this week.

🏆

Family challenges

Join community challenges, post progress photos to your feed, story, or challenge group, and climb the leaderboard together.

💬

Age-group forums

Every test and every drill has its own discussion space, bucketed by age group — compare notes with parents in the same boat.

📈

Standards that grow with them

Set Foundation, Performance, or Elite goals per skill. The dose adapts to age, sex, and maturity — never one-size-fits-all.

🔒

Privacy by design

Accounts belong to parents, never children. Your family's data is yours — export or delete it completely, anytime.

FAQs

Questions parents ask

What ages is XYeed for?
Children roughly 4–14 years old. Every test, benchmark, and mission is banded by age group, and the training load follows long-term athlete development (LTAD) principles — play-based for the little ones, more structured as they grow.
Do we need any equipment?
No. Tests and missions are designed for living rooms, driveways, and parks. Where something helps (a ball, chalk, a tape measure), the app tells you — and suggests household alternatives.
What exactly is a percentile?
It ranks your child's result against same-age peers: 75th percentile means they outperformed 75% of kids their age in that test. We compute it per pillar (speed, power, endurance, balance, physical literacy) so you see the full athletic picture, not one number.
What does "bio-banded" mean?
Kids of the same age can be years apart in physical maturity. Using the Khamis-Roche method (your and your partner's heights plus your child's current height), we estimate where they are on their growth curve and adjust comparisons to their own pace — so kids who shot up early aren't overrated, and kids still growing are never counted out.
Is my child's data private?
Yes. Accounts are created and owned by parents — children never log in. Data is stored securely, never sold, and you can delete your family account (everything, permanently) from your profile at any time.
Does it work on my phone?
Yes. On iPhone, get the native app (App Store — currently via TestFlight during early access) for the full experience: push notifications, native sharing, offline missions. XYeed also runs in any modern phone browser at xyeed.com/app if you'd rather skip the download.
What does it cost?
XYeed is free while we're in early access. We'll always keep a meaningful free tier; advanced programs and gear recommendations may become paid later — we'll tell you long before anything changes.
Can I add more than one child?
Absolutely — one parent account supports the whole family. Each athlete gets their own scores, missions, and progress, and you switch between them with one tap.
