# Install and sign in

> Install Epsilo on iPhone or iPad and sign in to the workspace you already use on the web.

> [!NOTE]
>
> **Find it in** the [App Store](https://apps.apple.com/app/id6789561626), search Epsilo. **Works on** iPhone and iPad with iOS 18 or later. **Last updated** 9 Oct 2026.

## Overview

The app signs you in with the same login you use at one.epsilo.ai. Create your account on the web first, then sign in on iPhone. Your session stays signed in until you sign out.

## How it works

**1. Create your account on the web**

Sign up at one.epsilo.ai and connect an ad account there. See [Connect your first ad account](https://epsilo.ai/docs/getting-started/connect-your-first-ad-account.md).

**2. Install the app**

Get [Epsilo on the App Store](https://apps.apple.com/app/id6789561626). If you open one.epsilo.ai in Safari on iPhone, the banner at the top also offers the app.

**3. Sign in**

Open the app and tap **Continue** on **Welcome to Epsilo**. Sign in with the same method you use on the web.

**4. Open your workspace**

The app opens on Console in your workspace, with your ad accounts already there.

## Use it

### Join or start a workspace

If your login is not part of a workspace yet, the app shows what you can open:

* An invitation from your team: tap **Join**.
* A workspace on your company domain: tap **Request to join**. You see **Waiting for an owner to approve** until an owner accepts.
* No workspace yet: tap **Start a workspace** and enter a **Workspace name** and **Workspace handle**.
* Wrong login: tap **Sign in with a different email**.

After you start a workspace, the app offers to connect your first ad account. Tap **Skip for now** to do it later.

### Switch workspace

Tap your avatar to open the account sheet. The **Workspace** section shows the current workspace and the others you belong to. **Create or join a workspace** opens the same options as above.

### Turn on AI features

The first time you open Console, the app asks for consent under **AI features in the Console**. Tap **Accept and enable AI features** to use Console, or **Not now** to use the rest of the app. Change it later in the account sheet, **AI features**.

### Sign out

Open the account sheet and tap **Sign out**. Conversations and drafts stored on the device are cleared, and the device stops getting notifications.
