Your Growth
Taller than 84% of teens your agePublished growth references
The projection comes from population growth data and your parents' heights, and it shows its margin of error instead of hiding it.
USDA nutrition data
Scanned meals are matched against the USDA database for calories, protein, calcium and vitamin D.
Targets from your own numbers
Sleep, nutrition and training targets are calculated from your profile, not handed out as one generic plan.
Six tools. One set of numbers.
Every screen runs on the same profile, so nothing ever asks you for your height twice.
Height predictor
Your projected adult height, with the range it could realistically land in. It updates every time you measure, so you watch the estimate tighten.
Percentile and growth left
Where you sit against your own age group, and how many centimetres are still ahead of you.
Sleep tracker
A nightly target for your age, your running sleep debt, and the streak that keeps you honest.
AI height coach
Ask it anything. It opens your logs before it answers, so what comes back is about you rather than about teenagers in general.
Meal scanner
Photograph a plate. Calories, protein, calcium and vitamin D come back filled in, and every number stays editable.
Exercise plans
Guided posture and mobility routines, timed and taken one step at a time so you always know what is next.
The screens you will open most.
Three of the six tools, as they look on the phone.

Advice that already knows your week
