Nanit alternative: when an app is enough
Nicolas Mathieu · · 7 min · Updated
Start with the part that decides most of this. Nanit tracks breathing motion using its own patterned band or swaddle, and it produces sleep analytics from what the camera sees overnight. MonitorUltra does neither of those things, and it is not going to. If breathing tracking is why Nanit is on your shortlist, no phone app replaces it, and you should stop reading here rather than let a comparison table talk you out of a decision you have already made correctly.
What is left once you set those two features aside is most of what a monitor does on an ordinary night: a live picture, live sound, and something that wakes you when the room does. That part an app on two iPhones handles well, at a very different price, with a very different data story.
What MonitorUltra actually is
MonitorUltra turns two Apple devices into a baby monitor. One iPhone or iPad sits in the child's room as the camera, the other stays with you as the viewer. It streams live video and audio, classifies crying on the device itself using Apple's SoundAnalysis framework, and sends push notifications. There is no breathing tracking, no sleep scoring, and no recording of any kind.
Use an undamaged iPhone or iPad running iOS or iPadOS 17 or later, with a working screen, camera and microphone. Check the device and charger before use. A SIM is unnecessary when the device has working Wi-Fi.
New installations of MonitorUltra require an active subscription to start monitoring, including audio. Any introductory trial depends on the selected App Store offer and eligibility. Existing installations with legacy audio access retain that access; it is not an offer for new users. Web plans cost $7.99/month or $49.99/year, with a 30-day money-back guarantee. You can cancel renewal at any time. App Store prices and trial terms are shown before you subscribe.
The two gaps, stated properly
Breathing motion
Nanit's breathing feature works from a garment with a printed pattern, which the camera watches for the small movements of a chest rising. MonitorUltra has no equivalent. Motion detection in the app is a general camera-based movement alert, which is a different thing at a different scale. It tells you a child has rolled or stood up. It says nothing about respiration.
Standard safe-sleep guidance is worth repeating here for any camera product: no monitor of any kind is a medical device, and none of them substitute for the sleep-environment advice your health visitor gives you.
Sleep analytics
The other Nanit feature people miss is the reporting. Sleep duration, wake counts, trends across weeks, comparisons over time. Some parents find that genuinely useful during sleep training, and some find it a source of anxiety at 4am. Either way, MonitorUltra produces none of it, because producing it would mean analysing and storing footage on a server, and the app does not store footage anywhere.
Where the app is clearly better
Cost. A nursery camera costs a few hundred pounds, and the analytics features that make it worth buying are usually a separate ongoing subscription on top. Check current numbers on the manufacturer's own site, since they move. The comparison to run is the camera price plus its subscription over the two or three years you will use it, against $49.99 a year and no hardware, on phones already in the house.
Nothing is recorded. MonitorUltra streams live and stores none of it. There is no clip history, no server-side footage of your child's bedroom, and nothing to appear in someone else's breach notification later. Video and audio are encrypted in transit and relayed through LiveKit. The reasoning behind that design is in what "private" should actually mean.
On-device detection. Crying is classified on the nursery device by SoundAnalysis, which is the same framework Apple ships for sound recognition in iOS. The audio is not uploaded for a remote model to listen to. That distinction is covered at length in on-device AI vs cloud AI.
Range. Streaming works over cellular as well as Wi-Fi, so the parent unit works in the garden, at the neighbours', or in the restaurant downstairs. A fixed nursery camera also reaches you remotely through its own app, so this is a smaller advantage than it looks, though it costs you nothing extra.
It packs. The monitor is an app. Taking it to a hotel or to grandparents means taking the two phones you were taking anyway, with no camera, mount or power brick in the bag.
It ends cleanly. When your child outgrows it you delete an app. There is no camera to store in a loft or sell on.
Where a dedicated camera is genuinely better
I would rather you buy the right thing than the thing I make, so this section is not decoration.
Night vision. This is the largest gap and the one people underestimate. Nursery cameras carry infrared LEDs and give a usable greyscale picture in a fully dark room. An iPhone has no infrared illuminator. In a blacked-out nursery you will see very little, and no software fixes that. The workable answer is a dim night light or a low-output lamp somewhere in the room, which many families run anyway. If you need a clear picture in total darkness, buy the hardware.
Mounting and field of view. A wall-mounted camera with a wide lens looking straight down at the cot gives a better view than a phone on a shelf, and it stays exactly where you put it. You can get close with a gooseneck clamp, and camera placement matters more than most people expect, but the ceiling-mount view is hard to match.
It is a single-purpose device. A phone in the nursery is still a phone. It can ring, it can show notifications, and someone can pick it up to check something and walk off with your camera. Leaving the SIM out of a spare device, or running it on Wi-Fi with Do Not Disturb, handles most of that. A camera bolted to the wall never has the problem in the first place.
Permanence. The nursery camera is always there and always on. A phone-based baby unit depends on someone remembering to put it back on its charger and open the app.
If you already own the camera
You do not have to switch. For a lot of people, keeping the camera is the better call.
A camera you have already paid for costs you nothing more to keep using in the room it is mounted in. Where an app helps is everywhere that camera is not. A second child in a different room, a week at grandparents', a hotel, a holiday let, the garden in summer. Adding a phone-based monitor for those cases costs you the price of the subscription for the months you use it, and you can cancel between trips.
The one thing worth checking, if you keep the hardware, is what its manufacturer stores. Any camera that offers you clip playback is keeping footage of your child's room somewhere. That is a reasonable trade for features you use. It is worth making the trade knowingly rather than by default, and worth reading the retention policy rather than the marketing page.
Working out which one you want
Buy or keep the dedicated camera if breathing tracking is the point, if you want overnight sleep reports, or if the room is pitch dark and you are not adding a night light.
The app makes more sense if you want a live view and reliable cry alerts, you already own a spare iPhone that runs iOS 17, and the idea of your nursery footage sitting on a company's servers bothers you. It also makes sense as a second monitor alongside hardware you already own, for travel or for a second room, since it costs no additional device.
Several parent devices can watch one baby unit and each gets its own alerts, with one subscription covering the household through family sharing. That is covered in how family sharing works.

Frequently asked questions
Does MonitorUltra track breathing? No. It has no breathing or vitals tracking of any kind, and no wearable component. Camera motion detection flags general movement in frame, which is a different feature.
Does it give me sleep reports? No. Nothing is recorded or analysed after the fact, so there is no data to build reports from.
Do I need to buy a camera? Use an undamaged iPhone or iPad running iOS or iPadOS 17 or later, with a working screen, camera and microphone. Check the device and charger before use. A SIM is unnecessary when the device has working Wi-Fi.
How good is the picture at night? It depends entirely on the room. With a night light or any ambient light the picture is good. In a completely dark room it is poor, because phones have no infrared illuminator.
Is there a subscription? New installations of MonitorUltra require an active subscription to start monitoring, including audio. Any introductory trial depends on the selected App Store offer and eligibility. Existing installations with legacy audio access retain that access; it is not an offer for new users.
Web plans cost $7.99/month or $49.99/year, with a 30-day money-back guarantee. You can cancel renewal at any time. App Store prices and trial terms are shown before you subscribe.
