If you're feeding a baby at 3 a.m., reaching for your phone to start a timer is one step too many. Logging from your wrist is the reason many parents look for a baby tracker with an Apple Watch app.
The catch: "works with Apple Watch" can mean very different things. Some apps let you log almost everything from the watch; some only show information; and in at least one popular app the watch app is part of the paid plan.
We checked each app below against its official App Store listing and the developer's own help pages on September 27, 2026. Where a developer doesn't say something publicly, we write "not stated" rather than guess.
What to look for
- What you can log from the watch. Feeding (breast and bottle), sleep, diapers, pumping — and whether there are timers you can start and stop on the wrist.
- Whether the watch app is free. This varies more than you'd expect.
- Complications. Information on your watch face, so you can see the last feed without opening anything.
- iPhone widgets and Live Activities. Useful when the watch isn't on your wrist.
- Ads and tracking. The App Store's privacy label lists "Data Used to Track You" for each app. It is self-reported by developers.

App by app
Huckleberry
Huckleberry is the best-known baby tracker in the US and an Apple Editors' Choice. Its watch app is well documented: you can log sleep, nursing, bottle, pumping, diapers and potty, and run sleep, nursing and pumping timers that sync with the iPhone in real time (Huckleberry help).
Good to know: Huckleberry's help center says the Apple Watch app is not available for free subscribers (source). iPhone widgets and Live Activities are also Plus and Premium features. If you're paying anyway, its SweetSpot nap predictions are its best-known feature.
Baby Tracker – Newborn Log (Nighp)
With about 227,000 ratings, this is by far the most-reviewed baby tracker we looked at. It supports Apple Watch, widgets, Live Activities and Siri shortcuts, and says core tracking stays free. The free version shows ads; a "Remove Ads" purchase is listed on the App Store. Its "What's Next" predictions are made on the device.
Nara Baby
Nara is ad-free and has one plan that covers the whole family, with unlimited caregivers. Its FAQ says that after a 7-day trial you need a subscription or a one-time purchase to keep logging (Nara FAQ). It supports Apple Watch and Live Activities, though it doesn't list what you can log from the watch.
Sprout Baby
Sprout's App Store listing (under the name "Baby Tracker & Newborn Log") says you can log feeding, sleep and diaper changes from Apple Watch and use the double-tap gesture. It also has interactive widgets, Live Activities, a sleep forecast built from its own long-running data, and a way to turn memories into a PDF book.
Baby Daybook
Baby Daybook documents its watch features more clearly than most: you can track feedings, diapers and naps, and put single or multiple activities on your watch face as complications (Baby Daybook). It also has widgets and Live Activities, and you can attach photos to any activity and build an album in the same app.
Baby Feed Timer
If you'd rather not subscribe, Baby Feed Timer is a one-time purchase after a trial. From the watch you can log breastfeeds, bottles, sleep, diapers and pumps and see when the next feed is due, and its listing says the watch app works even when the iPhone is switched off.
Baby Tracker • My Baby
This is one of the few watch-compatible trackers that is completely free: its listing says it has no in-app purchases, subscriptions or ads. Note that it requires watchOS 26.2 or later, so older watches can't install it.
PiyoLog
PiyoLog is popular in Japan and supports Apple Watch complications for its breastfeeding timer and the latest meal, sleep and diaper entries. The free version shows ads.
Memori Baby (ours)
We make Memori Baby, so weigh this section accordingly. From the watch you can log 11 kinds of events, including a left/right breastfeeding timer, and you can log by voice. Complications on the watch face show the next predicted feed or nap, which comes from the paid plan; logging on the watch and the widgets are free. There are no ads, and the iOS app contains no advertising or analytics SDKs.
Where others are ahead: Memori Baby launched on September 23, 2026, so it has very few ratings so far. It does not have Live Activities, it is iPhone-only (no Android), and Huckleberry and Sprout have much longer track records with their sleep predictions.
Which one to choose
- You want the most proven app and don't mind paying: Huckleberry.
- You want free core tracking with the biggest user base: Baby Tracker – Newborn Log (ads in the free version).
- You want no subscription at all: Baby Feed Timer (one-time purchase) or Baby Tracker • My Baby (free).
- You want watch-face complications that are clearly documented: Baby Daybook.
- You want to log from the watch and keep a private family photo album in the same app: Memori Baby — with the caveat that it's new.
