# Install the app and sign in

> Get OrthOS on your iPhone or iPad, and sign in on the web.

You use the same email and password everywhere.

## On iPhone or iPad

**1. Install OrthOS**

Use the install link your Operant Health contact sends you. The app appears on your home screen as **OrthOS**.

**2. Sign in**

Enter your **Email** and **Password**, then tap **Sign in**. iCloud Keychain can fill in your password.

**3. Allow the microphone**

The first time you record, the app asks for microphone access. Tap **Allow**. Without it, the app can't record visits.

## On the web

Go to [orthoshealth.ai/sign-in](https://orthoshealth.ai/sign-in) and sign in with the same email and password. Use Chrome if your practice will send notes to Practice Fusion. See [send notes to your EHR](https://help.operanthealth.com/docs/notes/send-to-your-ehr.md).

## Forgot your password?

Tap or click **Forgot?**, enter your email and choose **Send reset link**. Open the link from your email and set a new password. If you're on the app, go back to it and sign in.
