# Which Bluedeer links open in the app?

Explains which bluedeer.ai links the phone app opens, how team invitation links work, and where the Android and iPhone apps differ.

Some links on bluedeer.ai open straight in the Bluedeer app instead of your browser. Which links do this depends on your phone.

## Which links open the app

- **On iPhone**, two kinds of bluedeer.ai link open the app: the sign-in return address (bluedeer.ai/auth/federated) and team invitation links (bluedeer.ai/invites/...), including those in invitation emails. Other bluedeer.ai links, including links on other subdomains, open in your browser.
- **On Android**, only the sign-in return address (bluedeer.ai/auth/federated) opens the app. Other links, including team invitation links, open in your browser.

When you sign in with Apple, the browser sheet returns you to the app. If the app was closed when the sign-in finished, the link opens the app at its start screen, which shows sign-in or Home.

## Team invitation links

Tap the link in the invitation email. The invitation screen shows the team and one button.

- If you are not signed in, the button says **Sign up to join**. The invitation is kept, and it is used after you verify your email address.
- If you are signed in, the button says **Join** followed by the team name. If the team name is hidden, it says **Join workspace**.

An invitation works only with the email address it was sent to. If you sign in with a different address, the app says "This invite was sent to" your invited address and asks you to sign in with that one.

If the invitation has expired or was already used, the app says "This invite has expired or was already used."
