Owlet vs Nanit: an honest comparison

What each one actually is

Owlet Dream Sock

A sock that slips onto baby's foot. Inside the sock is a pulse oximeter that measures heart rate and oxygen saturation. It connects via Bluetooth to a base station, which uploads to the Owlet app. The Owlet Camera is a separate product, sold separately.

Owlet stopped selling the original Smart Sock 3 after an FDA letter in 2021. The current Dream Sock (BabySat in Europe) is positioned as a wellness device, not a medical device.

Nanit Pro Camera

A ceiling-mounted HD camera with a phone app. It captures sleep timing, position, breathing motion (with an optional fabric band), and room temperature. No vitals like heart rate or oxygen.

Nanit's value is the camera (very good) and the sleep analytics (estimates from movement). It is a fancy monitor, not a medical device.

Side by side

• Measures heart rate: Owlet yes, Nanit no.
• Measures oxygen: Owlet yes, Nanit no.
• Tracks breathing motion: Owlet yes (indirect via sensors), Nanit yes (visual via band).
• HD video: Owlet camera yes (sold separately), Nanit yes (included).
• Sleep analytics dashboard: Both, but Nanit's is more detailed.
• Cloud subscription: Both have optional subscriptions for full features. Both work at a basic level without them.
• Standalone WiFi monitor: Both require WiFi.

Price (2026)

• Owlet Dream Sock: around $300.
• Owlet Cam 2: around $150.
• Owlet Duo (sock + camera): around $400.
• Nanit Pro Camera: around $300.
• Nanit Breathing Band: around $40 (sold separately).
• Nanit Insights subscription: $5 to $10 per month after first year.

What the AAP says

Both products are explicit that they are not medical devices and not for SIDS prevention. The AAP technical report on safe sleep states: "There is no evidence that home cardiorespiratory monitors reduce SIDS, and they should not be used as a replacement for safe sleep practices."

What does reduce SIDS risk: back sleeping on a firm flat surface, in a clear crib, in the parents' room for the first 6 months, breastfeeding when possible, pacifier at sleep time, avoiding smoke exposure.

If your pediatrician has prescribed a medical-grade monitor for a specific condition (apnea, prematurity, etc.), neither Owlet nor Nanit replaces that.

When each one is actually useful

Pick Owlet if

• You have severe anxiety and a vitals number lets you sleep at night (real reason, no shame).
• You are exclusively pumping or have feeding challenges and want to track baby's heart rate during sleep for peace of mind.
• Your baby was premature or has a known condition where you want extra data (with pediatrician approval and ideally medical-grade gear).

Pick Nanit if

• You want a beautiful camera and detailed sleep tracking dashboards.
• You travel often and want phone-based monitor access from anywhere.
• You like data and will actually use the sleep insights to adjust schedules.
• You want the cleanest image at the highest price point.

Skip both if

• You want a simple, reliable, secure monitor. Get a radio-frequency monitor for under $100.
• You are anxious now and worry the data will make it worse. (Honest self-assessment matters here.)
• Your baby is healthy with no medical reason for vitals monitoring.

The false-alarm problem

Both Owlet and Nanit will alert you to readings that turn out to be nothing. Owlet's sock can give false alarms when the baby's foot is cold, when the sensor slips, or when baby's circulation is normal but the sock did not catch it. Nanit's breathing band can lose tracking when baby rolls or kicks the band loose.

The result: middle-of-the-night alarms that wake you up, scare you, and turn out to be a sensor issue. For some parents this is fine. For others, the cumulative cortisol spikes are worse than not having the device. Try the return policy. Both companies offer 30 to 60 days.

Privacy and data

Both apps require an account. Both store data in the cloud. Both have had security audits. Both have firmware updates.

Practical defaults: use a unique strong password, enable two-factor authentication, keep the app updated, and read the privacy policy before signing up. Both companies' policies say they do not sell baby data. They use it for product improvement.

What we recommend instead for most parents

For 80% of healthy babies, a $80 to $120 radio-frequency monitor handles everything. No app, no subscription, no false alarms, no hacking concerns. You see baby's face, you hear baby's cry, the battery lasts the night.

Spend the $300 you save on something with bigger payoff, like a quality car seat, a stroller that fits your life, or a deep cleaning service for the first month home from the hospital.

If you already bought one

Use it. The data point is: enjoy the features. Stick to safe sleep practices regardless of what the monitor says. The monitor is a comfort, not a guarantee. If false alarms are making you crazy, return it within the window or sell it on resale platforms. Many parents do.

Bottom line

Owlet and Nanit are good at different things. Neither prevents SIDS. Both can help anxious parents sleep, with the asterisk that false alarms can also make anxiety worse. Most healthy babies do not need either. The product to start with is a regular monitor, with anxiety check-ins along the way.
