# Connect your iPhone
> Pair locally, sign in for remote access, switch computers, and remove saved connections.

The mobile app can keep more than one environment connection. Each one has a stable identity and label even when its local network address changes.
## Nearby Mac [#nearby-mac]
1. Open **Settings → Connect to a nearby Mac**.
2. Select the discovered Mac, or wait while Zuse selects it when only one is nearby.
3. Compare the safety phrase on the phone and Mac.
4. Choose **Allow** on the Mac.
The phone stores a device credential and automatically follows new local routes for that same paired Mac. See [Pair a nearby iPhone](/remote/nearby-pairing.md) for QR fallback and approval details.
## Hosted computer [#hosted-computer]
1. Open **Settings → Remote access**.
2. Choose **Sign in for remote access**.
3. Sign in with the account used to link the computer.
4. Choose an online computer.
Account-linked environments appear as **Online**, **Offline**, or **Checking…**. The app automatically connects online environments and includes their chats in the inbox. Local connections continue to work after you sign out.
## Manual connection [#manual-connection]
Choose **Settings → Add manually** when discovery cannot be used and you know the environment's host and port. Manual setup is intended for a network route you administer; it does not create hosted reachability on its own.
## Connection states [#connection-states]
| State | Meaning |
| -------------------- | ------------------------------------------------------------------ |
| **Connected** | The live WebSocket is ready. |
| **Connecting** | Zuse is establishing or restoring the transport. |
| **Offline** | The app or network is unavailable; cached content remains visible. |
| **Connection error** | A retryable transport or authorization failure occurred. |
Use the recovery banner's **Retry** action first. Choose **Pair again** only when the credential is missing, expired, or revoked.
## Remove local data or access [#remove-local-data-or-access]
* **Clear downloaded data** removes cached projects, chats, and messages. Connections and unsent messages remain.
* **Reset app** removes account state, saved connections, device keys, cache, and unsent messages from the phone.
* Revoking the phone in the Mac's **Settings → Devices** ends its access at the environment.
* **Delete account** permanently removes the account, linked computers, device registrations, and cached chats. It cannot be undone.
If you wrote messages while offline, let them send before resetting the app unless you want to discard them.
