Smart Sock FAQs

  • Will the Smart Sock still work if my Wi-Fi goes out?
  • Yes! The Smart Sock communicates with the Base Station even in the event of Wi-Fi disruption, and will notify you with lights and sounds if your baby’s heart rate or oxygen drop below the preset levels. The Base Station is your primary notification device.
  • Can my baby wear footie pajamas or a swaddle with the Smart Sock?
  • The low-profile design of the Smart Sock was designed to be worn under footie pajamas, a sleep sack or a swaddle.
  • Does the Smart Sock work for multiples?
  • Yes, the Smart Sock works for multiples and each baby needs their own Smart Sock and Base Station unit. Parents can add each device to the Owlet app to view their babies’ live readings in the same app.
  • Does the Smart Sock work through motion?
  • The Smart Sock was designed to track during gentle motion and continues to track your baby’s heart rate and oxygen level through the gentle movement of sleep.
  • Can I use the Smart Sock with a Snoo?
  • Yes, the Smart Sock works during gentle motion and can be used in safe-sleeping bassinets like the Snoo.
  • What is the difference between Smart Sock 2 and Smart Sock 3?
  • The New Smart Sock 3 features entirely new hardware and design, based on feedback we heard from parents all over the world. With these changes, the Sock now fits babies both bigger and smaller—from 5 lbs. to 30 lbs. It also monitors babies through gentle motion, so you get live readings more often. And the redesigned Base Station offers wireless, drop-and-go charging—a huge time saver! Get an 8 hour charge in under 20 minutes, and a full 16 hours in 90 minutes.
  • Do you have to pay extra to use the app?
  • The Owlet App is free to download in the App Store or Google Play Store. The app requires iOS 13 or higher and Android 7.0 or higher.

  • Does the Smart Sock leave red marks on the baby’s foot? 
  • Red marks from the Owlet Smart Sock are not a common occurrence. The small number of users who notice red marks on their baby’s foot after using the Smart Sock have found that the Sock was on too tight or they were using the wrong size fabric sock. The Smart Sock is similar to when a baby shoe is too tight or too small and leads to discomfort for the child or the potential for pressure marks. Our research, in partnership with dermatologists and pediatricians, shows that these rarely occurring marks are not burns.
