# The model

Explore is the home of the app. A body model fills the screen. Country, age, gender, and percentile sit on the control bar. Pick a measurement and the model marks where that dimension is read.

## Controls

- **Country** chooses the population. The list is the [country catalog](https://docs.humanform.app/countries).
- **Age** runs from 1 to 88.
- **Gender** is male, female, or everyone.
- **Percentile** runs from 1 to 99.
- **Search** finds a measurement by name. See [Search](https://docs.humanform.app/search).

Pin a measurement to keep it in the sidebar. Recent Vault entries appear there too.

## The mesh

The standing model is an authored mannequin. Sitting, span, grip, and reach measurements switch pose so the landmark matches the dimension. The overlay is a guide to the measurement. The millimetres still come from Atlas, not from measuring the mesh.

Tap a marked measurement to open its detail: the predicted value, how it is taken, related measurements, and links to [charts](https://docs.humanform.app/charts).

## Inspector

The inspector collects the actions for the current measurement, including charts, the data table, export, and the design tools when they apply. [Humanform Pro](https://docs.humanform.app/pro) gates the full catalog and those tools.
