# Apps in a context

Every context aggregates its content into **built-in apps**, and a hive admin can
install **custom apps** on top. Apps see data through the same scope law as
everything else: only what the person using them can see, never beyond it.

## The built-in apps

| App | What it collects |
|---|---|
| **Gallery** | every image and video posted in the context subtree |
| **Notes** | editable documents created from the composer |
| **Tasks** | tasks attached to messages, with status |
| **Planner** | events attached to messages, on a calendar |
| **AnyDocs** | every file and link, in one searchable place |

Open them from the **Apps** card on the context dashboard. Content opens
full-screen with the original message beside it, so nothing loses its context.

## Install a custom app (admins)

1. Open the context and find the **Apps** card on the dashboard.
2. Choose **Add app** (visible to admins).
3. Pick an app from the catalog and choose **Add**. It appears under *Installed apps*.
4. Open it from the Apps card — **embedded** apps render in place; **external** apps
   open in a new window (or the in-app browser on mobile).

Remove an app anytime from its menu — its access stops immediately.

## Professional app families

SweetHive also hosts production app families used by thousands of organisations —
for example the **Safety-BI** document and training registries (**DocBI**,
**Document BI**, **Records**, **DBI Global**), used for per-employee certificates,
context document management and employee records. If your organisation uses them,
they appear in the context's Apps card like any other app.
