Good to see you here in the Community, @usermelanie2.
I'd be glad to help you install the app on your iPhone device.
Here's how:
1. Open the App Store on your device and search for QuickBooks Online.
2. Select Free, then Install.
3. If you already signed up for QuickBooks Online, use the same user ID and password to sign in to the app.
4. You will be asked to confirm a one-time confirmation code to confirm your identity. Once confirmed, you can continue with your account.
I've also added this link about the QuickBooks Online mobile app features: Compare mobile app features.
Reach out to me if you have any other questions. I'm always here to help. Have a great day!
