How tall will you
actually be?
A minute of questions gives you your projected adult height, your percentile, and how much growth you have left. Then a daily plan built from your own numbers.

Published growth references
The projection comes from population growth data and your parents' heights, and it shows its margin of error instead of hiding it.
Nothing logs itself
A scanned meal arrives filled in but unsaved. Every gram and every nutrient is editable, and nothing reaches your log until you have checked it.
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, straight from the app.
Advice that already knows your week
It reads your logs before it answers, so nothing it says is generic.
One photo fills in the day
The four numbers that matter for growth, tracked without weighing anything.
The input you can fix tonight
Log a bedtime and a wake time, and see it against the range set for your age.
