Ozmium is a progressive web app. There is nothing in an app store, nothing to download, and no
review process between a change being shipped and you having it. Adding it to your device takes a few
taps and produces an icon that behaves like any other app: its own window, no browser chrome, and its
own place on your home screen.

Four hosts are supported, and all of them run the same site.

## iPhone and iPad

Safari is required for this. Chrome and Firefox on iOS can open Ozmium perfectly well, but only
Safari can write to the home screen.

1. Open [ozmium.org](https://ozmium.org) in **Safari**.
2. Tap the **Share** button in the toolbar, the square with an arrow pointing up.
3. Scroll down the share sheet and tap **Add to Home Screen**.
4. Confirm the name, leave **Open as Web App** enabled, and tap **Add**.

<div class="oz-mosaic">

![The Add to Home Screen dialog with Open as Web App enabled and the Add button highlighted.](/img/ios-install-3-confirm.svg "Keep Open as Web App on, then Add.")

</div>

The icon lands on your home screen. Opening it launches Ozmium full-screen without the address bar,
and it keeps its own session, so a connected wallet stays connected between launches.

If you do not see **Add to Home Screen**, you are in a browser other than Safari, or the option is
below the visible area of the sheet. Scroll further.

## Android

Chrome usually offers this on its own. If it has not:

1. Open [ozmium.org](https://ozmium.org) in **Chrome**.
2. Tap the **three-dot menu** in the top right.
3. Tap **Add to Home screen**, or **Install app** if Chrome offers that instead.
4. Confirm.

Samsung Internet, Edge, and Firefox on Android all support the same thing under similar wording.

## Desktop

Chrome and Edge both install web apps on Windows, macOS, and Linux. Look for the **install icon** in
the address bar, a small monitor with a downward arrow, or open the browser menu and choose
**Install Ozmium** or **Apps, Install this site as an app**.

The result is a standalone window with its own taskbar or dock entry.

## The Base App

Inside the [Base App](https://base.app/invite/ozbeta/D1H4FT25), Ozmium opens as a mini-app with the
host wallet already connected, so there is no separate connection step.

1. Open the Base App and go to its **browser**.
2. Enter **ozmium.org** in the address field.
3. Once Ozmium loads, open the **three-dot menu** in the browser bar and choose **Pin**. The same
   menu manages notifications for the pinned app.

Base publishes no end-user guide for its browser or for pinning apps, so the steps above are
described from the app itself rather than cited. [docs.base.org](https://docs.base.org) is developer
documentation, and its [mini-apps section](https://docs.base.org/mini-apps) covers how a mini-app is
built rather than how you pin one. If the Base App changes its controls, trust the app over this
page.

## Farcaster

Ozmium is also a [Farcaster](https://farcaster.xyz/~/code/1914H5) mini-app. Opened from a cast or from the mini-app directory, the wallet
your Farcaster client already holds is the wallet Ozmium uses.

1. Open your Farcaster client.
2. Find Ozmium through the **mini-apps directory**, or open any cast linking to it.
3. Add it to your own mini-apps list using the client's add control.

[miniapps.farcaster.xyz](https://miniapps.farcaster.xyz) is likewise developer documentation. It
describes how clients handle mini-apps, not how you add one, and the add control differs between
Farcaster clients.

## What Installing Changes

Installing changes presentation and nothing else. There is no separate build, no additional
permission, and no extra access to your device. It is the same site, in its own window.
