Overview

Height Predictor ships on the App Store as Bone Age Height Predictor, an iOS clinical reference tool for predicting adult height from bone age using Bayley-Pinneau tables. Choose boy or girl, pick advanced, average, or delayed skeletal tempo, enter current height in inches and bone age in years, then look up the predicted adult height on device. Tables ship with the app, so the core calculation works offline. Built for pediatric clinicians and trainees who already have a scored bone age, not for consumer guessing at home. Requires iOS or iPadOS 18.6 or later. Available now on the App Store.

Key features

  • Bayley-Pinneau tables

    Sex-specific advanced, average, and delayed tempo tables for predicted adult height from bone age.

  • Fast clinical inputs

    Enter current height and bone age after choosing sex and growth tempo, then look up the result.

  • Works offline

    Digitized tables live on the device. No account and no network required for the core lookup.

  • Built for clinicians

    Assumes a scored bone age from clinical practice. Not a consumer toy or parent height guessing app.

Benefits

Why people choose Height Predictor for real workflows and everyday play.

  • Faster Bayley-Pinneau lookups

    Get a predicted adult height from sex, growth tempo, current height, and bone age without flipping paper tables mid-visit.

  • Tempo-matched tables on device

    Advanced, average, and delayed tables ship with the app so the core lookup works offline in clinic.

  • Clear clinician framing

    The tool assumes a scored bone age. It is a reference aid for growth evaluation, not a parent guessing game.

Use cases

Practical ways people use Height Predictor day to day.

  • Pediatric endocrinologists

    Clinic growth evaluation

    When radiology already returned a bone age, look up predicted adult height before you leave the room.

  • Residents and fellows

    Teaching the method

    Walk through sex, tempo, height, and bone age inputs so trainees see how Bayley-Pinneau tables are applied.

  • Pediatric clinicians

    Offline reference between patients

    Run the lookup on device when Wi-Fi is poor or you do not want another browser tab open.

Frequently asked questions

Quick answers about Height Predictor, platforms, and who it is for.

Who is Height Predictor for?

Pediatric clinicians and trainees who need a Bayley-Pinneau predicted adult height from a scored bone age. It is not a consumer diagnostic app for parents.

What method does it use?

Bayley-Pinneau tables digitized for boy and girl paths across advanced, average, and delayed growth tempo. The app looks up the nearest supported table entry for your inputs.

Where can I get Height Predictor?

It is available now on the App Store for iOS. Open the product page for the download link.

Does it score bone age from an X-ray?

No. You enter a bone age that was already assessed clinically. The app predicts adult height from that bone age plus current height and growth tempo.

What bone age ranges are supported?

Boys: 7 to 17 years for advanced tempo, 7 years through skeletal maturity for average, and 6 to 13 years for delayed. Girls: 7 to 17 years for advanced, 6 to 18 for average, and 6 to 17 for delayed. Inputs outside a table are matched to the nearest supported entry.

What units does it use?

Current height is entered in inches and bone age in years, matching the digitized Bayley-Pinneau tables. There is no centimeter input in the current build.

What does it require, and can institutions buy it?

It runs on iPhone and iPad with iOS or iPadOS 18.6 or later. Device-based volume licensing through Apple Business Manager is enabled for clinics and training programs.

Why is the App Store listing named Bone Age Height Predictor?

Bone Age Height Predictor is the store listing name; Height Predictor is the short name used on this site. Same app, same developer.

Is this the same as mid-parental target height?

No. Mid-parental target height comes from parental heights. Bayley-Pinneau predicted adult height comes from current height and a scored bone age with tempo-specific tables.
