+
+## Testing on Mobile Devices
+
+When developing Element Call locally, you may want to test on physical mobile devices (iOS/Android)
+on the same WiFi network.
+
+**Known Limitations:** For now this setup allows to use your local EC server but not yet the SFUs and Synapses.
+
+### Prerequisites
+
+1. **Start the dev server**
+
+   ```bash
+   pnpm dev
+   ```
+
+Check the output for the `➜  Network` (this will contain the local IP address of your laptop)
+
+```
+  ➜  Local:   https://m.localhost:3000/                                                                                                                                                                 12:06:48
+  ➜  Local:   https://vite.m.localhost:3000/                                                                                                                                                            12:06:48
+  ➜  Local:   https://vite.othersite.m.localhost:3000/                                                                                                                                                  12:06:48
+  ➜  Local:   https://vite.nip.io:3000/                                                                                                                                                                 12:06:48
+  ➜  Network: https://192.168.0.122:3000/
+```
+
+2. **Transfer the CA certificate to your phone**
+
+   The file is located at `backend/dev_tls_local-ca.crt`. Transfer it via:
+   - Matrix room
+   - AirDrop for iphone
+
+### IOS Setup
+
+**Install the certificate profile on iPhone**
+
+- Open the `dev_tls_local-ca.crt` file on your iPhone
+- You'll see "Profile Downloaded"
+- Go to **Settings → General → VPN & Device Management** (or **Settings → General → Profiles**)
+- Tap the "Element Call Dev CA" profile
+- Tap **Install** and enter your passcode
+- Confirm by tapping **Install** again
+
+**Enable full trust (Critical!)**
+
+- Go to **Settings → General → About → Certificate Trust Settings**
+- Under "Enable Full Trust for Root Certificates"
+- Toggle **ON** for "Element Call Dev CA"
+- Confirm the security warning
+
+**Access Element Call**
+
+Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Safari to validate:
+
+```
+https://192-168-0-122.nip.io:3000/
+```
+
+**For Element X iOS Developer Tools**
+
+In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
+
+```
+https://192-168-0-122.nip.io:3000/room
+```
+
+### Android Setup
+
+**Transfer the CA certificate to your Android device**
+
+The file is located at `backend/dev_tls_local-ca.crt`.
+
+**Install the certificate**
+
+This might vary by Android version and manufacturer, but generally:
+
+- Open **Settings** search for "CA Certificate"/"Certificate"
+- Tap **Install a certificate** or **Install from storage**
+- Select **CA certificate**
+- Confirm the security warning
+- Navigate to and select the `dev_tls_local-ca.crt` file
+- Give it a name like "Element Call Dev CA"
+
+**Access Element Call**
+
+Find your laptop's IP address (e.g., `192.168.0.122`) and use one of these URLs in Chrome to validate:
+
+```
+https://192-168-0-122.nip.io:3000/
+```
+
+**For Element X Android Developer Tools**
+
+In Element X's developer settings, set the Element Call URL to the nip.io url (replace . with - in the IP address):
+
+```
+https://192-168-0-122.nip.io:3000/room
+```
+
+### Why nip.io?
+
+[nip.io](https://nip.io) is a free wildcard DNS service that automatically resolves domain names containing IP addresses. For example, `192-168-0-122.nip.io` automatically resolves to `192.168.0.122`. This means:
+
+- No need to regenerate certificates when your laptop's IP changes
+- Works from any device without DNS configuration
+- iOS/Android treat it as a proper domain name, not an IP address
+- One-time certificate setup works for all future IP addresses
+
+> [!IMPORTANT]
+> Make sure your network router doesn't enforce DNS rebinding protection (which will
+> break nip.io). If it does, try allow-listing nip.io in your router's administration interface.
