Timmy Web Companion brings Baby Monitor Timmy into the browser. Open it at app.babyphone-timmy.ch and pair it with a phone where Timmy is already set up. It is not a new product with its own subscription; existing premium users get an extra way in.
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 either role. If the mobile app runs as the baby device, the browser listens as the parent side. If the mobile app runs as the parent side, the browser sends as the baby device. You choose the role when the session starts; it must match the paired phone.
In Parent mode, the browser receives audio and, if enabled, video. In Baby mode, it sends audio and camera video like a baby device. In the background, a browser is more limited than the native app because power saving, tabs, and permissions are managed more strictly.
Why the premium app remains the gatekeeper
The browser app stores no subscription of its own and gets no permanent infrastructure access. The premium app on your phone authorizes each web session. Only then does the browser receive short-lived connection data for that 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 principle as in the app. Browser and phone meet through a short code, exchange cryptographic keys, and show safety digits. If the digits match, you are connecting those two devices.
The short code is only a meeting point, not the secret key for audio or video. The real keys are created fresh during pairing and then protect 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 active tabs, not hours-long background services. Keep Web Companion visible in the foreground while using it. For reliable long-running monitoring with battery-saving logic, the native Timmy app is still the better 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.
