Use two phones as a baby monitor
The spare phone in the drawer has a job again.
A spare phone plus the one in your pocket makes a free baby monitor. Two iPhones, two Android phones, or one of each all work: one device stays in the nursery as the baby unit and the other goes with you as the parent unit. You get live audio, cry alerts, hold-to-talk, and optional video on your home Wi-Fi, with no camera to buy and no second app to install.
Set up two iPhones or Android phones
There is no pairing step for this one. Two iPhones, two Android phones, or one of each find each other once Vaava is open on both and they share a Wi-Fi network.
- Install Vaava on the spare phone and place it in the nursery, plugged in and with the screen kept awake.
- Put both phones on the same Wi-Fi network and make sure neither is on a VPN, which can hide them from each other.
- Open the baby monitor in Vaava on the nursery phone and set it as the baby unit.
- Open the same screen on your own phone and set it as the parent unit, then check that you hear the nursery.
- Test the alerts before you rely on them. Make a noise near the baby unit, confirm the parent unit reacts, then try hold-to-talk from the parent unit.
How monitor audio and video travel
On the same Wi-Fi network, live audio and optional live video travel directly between the two devices. They do not pass through Vaava's backend or an external relay service, which is why local monitoring is free and works on a Wi-Fi network with no internet connection.
Both the free local mode and Vaava Plus remote monitoring support optional live video. Video is optional, so the monitor can run audio-only, and the parent phone keeps playing the nursery with its screen locked or another app open. Cry alerts tell you when the baby unit detects crying, so you do not have to watch the screen. Neither audio nor video is recorded or stored for later playback.
Monitoring when you are not on the home network
Local monitoring works on your own network. If you need to monitor the nursery from another building or over cellular data, Vaava Plus extends the monitor over the internet with encrypted live audio and optional live video. Both devices need internet for remote monitoring.
If the internet route fails, the local Wi-Fi mode stays available as a fallback, so using Plus never takes away the free in-home mode.
One app instead of two
The reason this works without extra hardware is that the monitor sits next to the tracker. The phone in the nursery is already logging naps, and the phone in your hand is already showing the last feed, so you are not switching between a camera app and a log app while holding a baby.
If you want the second phone to follow the timeline as well, pair the two phones for local Wi-Fi data sharing. It uses the same network and stays free. If you have an unused device at home, see our guide on how to turn an old phone into a baby monitor for power and setup recommendations.

FAQ
Can I use two phones as a baby monitor for free?
Yes. One phone acts as the baby unit and another household phone as the parent unit, with cry alerts and hold-to-talk, free on your own Wi-Fi. No extra hardware or subscription is needed.
Does the baby monitor work without internet?
Yes, as long as both phones are on the same Wi-Fi network. Live audio and video travel directly between the two devices and do not pass through Vaava's backend or an external relay, so a Wi-Fi network without internet access is enough. It does need a Wi-Fi network, though: with no Wi-Fi at all, the phones cannot reach each other. Monitoring across different networks needs optional Vaava Plus and internet on both devices.
Is baby-monitor audio or video recorded or stored?
No. The live audio and optional live video are not recorded or stored for playback. Both the free local Wi-Fi mode and Vaava Plus remote monitoring support optional live video.
Why is local monitoring free?
Because there is no server in the middle. The two phones connect directly over your network, so there is no bandwidth or relay cost to cover, which is why the local mode is free and the internet mode is part of Vaava Plus.
Do both phones need to be on the same Wi-Fi?
For the free local monitor, yes. Both devices have to be on the same network. When you need to monitor from somewhere else, Vaava Plus extends the monitor over the internet, and local Wi-Fi stays available as a fallback.
