How it starts

    Eight short questions, including your height today and, if you know them, your mom's and your dad's. No name and no email.

  2. See your range

    Your estimated adult height, always with its range, and your percentile today. Free, and calculated on your phone.

  3. Start your habits

    Sleep, posture and meals, one at a time. Habits protect your growth; they do not increase it.

Profile, estimate and records for free. PDF report with the plan.

  • If their percentile drops a lot between two measurements, the app flags it as a caution and invites you to talk it over with their pediatrician.
  • It asks for a nickname, never their name. You sign in with Apple or with your email.

How it is calculated and how we look after your data

Questions before you start

Is it free?

Your estimate with its range, measuring yourself every month and your three base habits are free for good. The plan is a subscription; you see the price in the app before you pay.

How accurate is the estimate?

No estimate is exact, which is why you always see a range. 9 in 10 estimates fall within the range we show you, and the range widens when a piece of data is missing.

Will any habit make me taller?

No. No habit, exercise or supplement lengthens bones. Sleeping, moving and eating well protect the growth your body already has under way, and that is what the app helps you look after.

What if I do not know how tall my parents are?

Choose «I don't know» and carry on. We use an average population height for that value, and the range widens to cover what it could have been.

What happens to my data?

If you are a teenager, we do not ask for your name or your email, and your result is calculated on your phone. In parent mode, the mother, father or guardian signs in with Apple or with their email, and each child goes by a nickname, never their name. When the app creates an account, the data is also stored on our server, in the European Union, and you can ask us to delete all of it from the app or from finalstat.app/en/delete.

Is FinalStat a diagnosis?

No. It is a health and wellness app, not a medical device. If anything about your growth worries you, talk to a pediatrician.

Which languages does it speak?

Spanish and English. The app follows your phone's language.
