Smart wake, not spam.
BabyRadar tells a real cry apart from the white-noise machine, the radiator, and the cat, so you only wake for a real cry.
A calmer night monitor · Free to startThe nursery is quiet.
The nursery is quiet.
Sleep while it listens.
Smart cry alerts on a phone you already own, iPhone or Android. Cry detection wakes you only when it matters, with no extra hardware. Free tier is sound-only. iPhone Pro adds crib photos and on-demand live video, auto-deleted after 90 days.
How it works
Three minutes to set up.
- 01
Dock a spare phone or tablet in the nursery.
An idle iPhone, iPad, or Android works. Plug it in, open BabyRadar, pick Monitor. It learns your room on the first night.
- 02
Pair your phone with a 6-digit code.
Open the app on your phone, tap Viewer, enter the code. Pair as many viewers as you want.
- 03
Sleep.
If the baby cries, a push notification wakes you. Tap to listen in live, from any room.
What it does
Fewer reasons to check the crib.
The sleep diary writes itself.
Wake up to last night's timeline: sleep windows, cry episodes, settle time. Event lookback included.
Hear the nursery from any room.
One-tap live listen, straight from the nursery phone to yours. And replay the audio around any event.
Two parents, one nursery.
Pair as many viewers as you want. Both parents get cry alerts and can listen in live.
Tuned to your room.
It learns your room on the first night, so the white-noise machine and the fan don't set off a false alarm.
Minimal cloud footprint.
Cry detection runs on your phone. Live audio is a direct encrypted relay. On iPhone Pro, cry clips and crib photos are held in encrypted cloud storage for 90 days so paired viewers can play them back, then auto-delete.
See it on a real phone.
Quiet by default. Loud when it matters. Real screens from a paired Monitor + Viewer.
Privacy
Your nursery, your data.
Cry detection runs on your phone. Only paired devices in your household can see clips or photos, and everything auto-deletes.
- The listening happens on your phone
- BabyRadar figures out cries, stirs, and quiet right on the phone in the nursery. No audio leaves your house to be analyzed.
- Live listen is direct, not recorded
- When you tap to listen in, audio streams straight from the nursery phone to yours through an encrypted relay. Live audio itself is never saved.
- Camera stays off between events
- iPhone Pro can snap a photo on a cry event and stream live video on demand. The camera is off the rest of the time. Free tier and Android are sound-only, no camera use.
- 30-day auto-delete on stored clips
- iPhone Pro clip audio and crib photos are held in encrypted cloud storage so paired viewers can play them back, then auto-delete after 90 days. Only your paired devices can read them.
- A sleep diary, not a doctor
- BabyRadar tracks sounds and writes a sleep timeline. It doesn't measure breathing or anything medical.
