# Use Explore cards and metrics on a phone

> On a phone, add Mammoth Explore cards to a View, tap values and Filter, and read the View's metrics, which follow your filters, with what each reads.
>
> Applies to: Where: View on a phone › Explore or Metrics

On a touch phone, the **Explore** and **Metrics** buttons under a View's title open its Explore cards and its metrics. You can filter with cards and read metrics; metrics are made in the data editor on a computer. Your filters change only your view, and nobody else sees them.

## Use Explore cards on a phone

**Explore** shows the same Explore cards as the data editor, one card per screen width. Swipe sideways to move between them. See [Explore Cards](https://mammoth.io/docs/learn/explore/explore-cards/).

1. Tap **Add a card**, then pick a column. Use **Find a column** to search the list. The new card goes first.
2. Tap values on a card to select them.
3. Tap the card's **Filter** button. There is no double-click on a phone.

A filter on a card filters the rows and the metrics too. When you fold the cards, the filters stay as pills: the column name and its values, or "not" the values for an exclude. Tap a pill to remove that filter, or **Clear** to remove them all.

## Check metrics on a phone

**Metrics** lists the View's metrics with their values. Metrics are read-only on a phone: they are made in the data editor on a computer. A View with none shows "This view has no metrics yet. They are made in the data editor on a computer."

Metrics follow your search and filters, and the sheet says so, for example "Metrics follow your filters: 120 of 1,240 rows." A metric locked in the data editor keeps its own filter and shows a lock icon.

Tap a metric to open it:

| Part | What it shows |
| --- | --- |
| Tag | **Your filters**, **All rows**, or **Fixed filter** for a locked metric |
| Value over all rows | When your filters are on: "All rows:" the full value, and what share of it the filtered value is |
| **Reads** | The columns the metric uses |
| **Rows counted** | How many rows went into the value. **Its own filter** for a locked metric |
| **Copy value** | Copies the value |
