Log in seconds
OBubba starts learning from the first log and gives you an immediate plan for improving sleep. After 24 hours, guidance begins to use your baby’s own records. Each new log gives OBubba more recent history to compare.
Your data is never sold
Your baby’s information is not shared with third parties. If you choose AI help, only the information needed for that analysis is shared with the AI service.
You control every carer
Only people you invite can see a baby’s profile, and only the information needed for that day’s care. Parents control what each carer sees and can turn care access on or off.
Nursery just needs a care link
Nursery does not need to download OBubba. A care link lets them record the day, while you remain in control of access.
Made for real families
Separate accounts. Shared care without oversharing.
Partners use their own accounts. OBubba supports blended families and multiple children, with access granted baby by baby. A parent can care for children with different partners without exposing anyone else’s information.
Parent sees both children.Full history, insights and controls stay with the parent. Each partner sees only the baby they have been invited to.

OBubba in brief
What is OBubba?
OBubba: Baby Sleep Tracker is a baby sleep, feeding and development tracker for iPhone and Android. It predicts naps and bedtime from your baby's own logs, gives guidance on nap transitions and sleep regressions, and keeps feeds, teething, solids, milestones, development waves, pregnancy and postpartum in one shared timeline.
How is OBubba different from other baby sleep apps?
Its nap and bedtime predictions learn from your own baby's logged days rather than one fixed age chart, and it reads sleep beside feeds, teething, new foods and development, so a harder patch comes with context. A partner can join the same live record, and a trusted carer can log the day from a private browser link without downloading the app. To check other apps side by side, see our comparison pages, which use each app's own public listing.
Is OBubba free?
OBubba is free to download and free to start logging. Premium is optional; the current price and any trial are shown in the app and on the App Store or Google Play listing for your country.
Who makes OBubba?
OBubba is built in the UK by a mum and published by OLife Labs Limited. The OBubba team answers questions at hello@obubba.com, and the press kit has verified product facts and images.
Does OBubba work for twins or more than one child?
Yes. OBubba supports multiple children, including twins, and each baby has their own record and sharing settings.
Is OBubba medical advice?
No. OBubba gives general, age-based information and suggestions based on your own logs. It is not a medical device and does not diagnose anything. If you are worried about your baby, speak to your health visitor, midwife or GP.
