Timmy Web Companion is the browser extension to the mobile app. Open it at app.babyphone-timmy.ch and pair it with a phone where Baby Monitor Timmy is already set up. The web version is not a separate product with its own subscription; it is an additional access point for existing premium users.
What you need
- A paired Timmy app: At least one Android phone must already be paired with your second Timmy device.
- Premium on the app side: The premium mobile app authorizes the browser session. There is no separate web subscription.
- A modern browser: The browser must support WebRTC and should stay in the foreground while Timmy is running.
- Microphone and camera access in Baby mode: If the browser sends as the baby device, it needs microphone and camera permission.
Browser as parent or baby device
Web Companion can take the role you need at that moment. If the mobile app is running as the baby device, the browser can listen as the parent side. If the mobile app is running as the parent side, the browser can send as the baby device. The role is chosen when the session starts and must match the role of the paired phone.
In Parent mode, the browser receives audio and — if enabled — video. In Baby mode, the browser sends audio and camera video like a baby device. Background behavior remains deliberately more limited in the browser than in the native app because browsers manage power, tabs, and permissions more strictly.
Why the premium app remains the gatekeeper
The browser app does not store its own subscription and does not receive permanent infrastructure credentials. Instead, the premium app on your phone authorizes every web session. Only after that authorization does the browser receive the short-lived connection data required for this session.
That keeps billing simple: one premium subscription in the mobile app is enough. You do not need to buy anything extra on the web or manage a second membership.
How pairing works
Pairing follows the same security principle as the app. The browser and phone meet through a short code, exchange cryptographic keys, and show safety digits. If the digits match, you know these exact two devices were connected.
The short code is only a meeting point. It is not the secret key for audio or video. The real keys are created fresh during pairing and are then used for encrypted signaling and the WebRTC connection.
The security model in plain language
- End-to-end connection: Audio and video run encrypted over WebRTC between browser and phone.
- No cloud recordings: Timmy does not record your streams in the cloud.
- Encrypted signaling: Technical connection data is additionally protected with a key derived from pairing.
- Short-lived credentials: Relay-server connection data is temporary and released per session.
- Premium app control: No production web session starts without an authorized premium app.
Important browser limits
Browsers are built for interactive tabs, not permanent background services. Keep Web Companion visible in the foreground while using it. If you need reliable long-running monitoring with battery-saving behavior, the native Timmy app remains the right choice.
Especially in Baby mode, check before use that the browser has microphone and camera access and that your device will stay awake for the planned monitoring period.
