Built by a parent, in Paris
Turn your iPhone into a baby monitor.
Use two iPhones or iPads running iOS 17 or later: one in the nursery, one with you. Watch live video over Wi-Fi or cellular, with on-device cry detection and no recordings.
Nothing recorded, ever
On-device cry detectionI am a developer in Paris and a father of two. We travel often, and I was done hauling a bulky baby monitor through airports, or reaching the rental at midnight and realising I had left it at home.
So I spent months building the app I could not find: one that met my needs. On holiday I use it to watch and listen to my kids without being stuck in the bedroom all evening, which means I can have a drink, talk to people and be a person for an hour. Keeping a session alive costs real infrastructure, and the subscription is what pays for it.
It records nothing, because I did not want footage of my own children sitting on anybody's server, including mine. That costs the app features other monitors have: there is no playback and no sleep history. I think it is the right trade, and if you disagree the refund runs for 30 days and I will not ask why.

Why MonitorUltra?
I built this because I couldn't find a baby monitor app that did what I needed consistently. So I built one that does.

Frequently asked questions
Do I need two iPhones?
Yes. One device acts as the camera in your baby's room, and the other is your viewing device. A compatible iPhone or iPad running iOS or iPadOS 17 or later can work, including a device you're no longer using.
Is my video stored in the cloud?
No. MonitorUltra never records your video or audio. The stream is encrypted in transit and relayed live to your parent device, so there is no recording, no clip history and nothing stored on a server. It works over Wi-Fi and over cellular, so you are not limited to one network.
Can both parents watch at the same time?
Absolutely. Multiple devices can connect simultaneously, and both parents receive push notifications and alerts.
How does AI crying detection work?
MonitorUltra analyzes sound on the baby unit. When crying is detected for your chosen duration, it sends a push notification even if the app is in the background. You can also tune sensitivity and the delay between repeat alerts.
Can I cancel my subscription anytime?
Yes. You can cancel anytime from your account. No questions asked, and you'll continue to have access until the end of your billing period.
What if I don't have a spare iPhone?
You can use a spare iPhone or iPad that supports iOS or iPadOS 17 or later as the baby unit. You can also use your partner's compatible device, and family features let authorized parents share access.
