On a computer, you use Line in your web browser. On an iPhone, you use the Line app from the App Store. There is no separate desktop app for Mac or Windows.

## Use Line on a computer

Sign in at [/login](https://useline.io/login) in your browser. The web app has every part of Line. You can make and take calls in the browser, reply to conversations, and change all settings.

- Calls ring in the browser only when your status is **Available**. See [Set your availability](https://useline.io/help/team/availability).
- To get alerts when the browser tab is in the background, turn on desktop alerts. See [Choose your notifications](https://useline.io/help/team/notifications).

## Get the iPhone app

1. On your iPhone, open the [Line website](https://useline.io/).
2. At the bottom of the page, select **Download on the App Store**.
3. Install the app.
4. Open the app and sign in with your Line email and password.

The app is free. It uses your Line account and workspace.

## Allow the microphone and notifications

After you sign in, the app asks for two permissions: the microphone, then notifications. You must allow both. The app does not open until you do. Line needs the microphone for calls. Line needs notifications to ring your phone and to show new messages.

If you said no before, the app opens your phone settings. Allow the permission there, then go back to Line.

## What you can do in the app

- Make and take calls. Incoming calls use the iPhone call screen.
- Reply to SMS, WhatsApp, Web Chat and email conversations.
- Use team chat.
- See calls, voicemails and contacts.
- Set your status and your active hours.
- Choose which channels send notifications to your phone.
- Add or change your profile photo.
- Send a message to Line support from **Profile** > **Contact support**.

## What you do on the web

Some tasks are on the web only:

- Build and change workflows. The app shows only the name of the workflow that handles a number or a channel.
- Pay for a number, change your plan, and see billing and usage. The app has no billing screen.
- Change the workspace-wide voicemail greeting.
- Change a team member's role or remove a member.

If you sign up in the app, the app saves the number you pick, but the number is not live yet. Line emails the workspace owner a link to finish setup on the web.

## Common problems

**My phone does not ring.** Check that your status is **Available**. Check that notifications are allowed for Line in your phone settings. See [Calls are not ringing](https://useline.io/help/troubleshooting/calls-not-ringing).

**The app shows a two-factor screen.** Your workspace asks for a second sign-in step. See [Turn on two-factor authentication](https://useline.io/help/team/two-factor-authentication).
