If you want the best smartwatches for pregnancy tracking, the strongest all-around choices are the Apple Watch Series 10 (for iPhone users), the Samsung Galaxy Watch7 (for Android users), and the Garmin Venu 3 or a Fitbit device (for multi-day battery and detailed sleep data). No consumer smartwatch is a medical monitor, and none is cleared to track a pregnancy or a baby’s heartbeat. What they do well is help you observe trends in your own rest, resting heart rate, activity, and stress—useful context to bring to your prenatal appointments, not a replacement for them.

What actually matters in a pregnancy smartwatch
Pregnancy changes your body in ways a wearable can passively observe. Blood volume rises, resting heart rate typically climbs, sleep gets fragmented, and comfort while wearing the watch becomes a real factor. When choosing, focus on the wellness signals that stay meaningful during these months rather than fitness bragging rights.
- Prioritize sleep tracking, resting heart rate trends, and comfort over step counts
- Smartwatches monitor YOUR wellness—they cannot track the baby or diagnose complications
- Always confirm anything unusual with your OB-GYN or midwife rather than the app
- Sleep tracking: Fragmented sleep is common, so a watch that logs duration and stages helps you spot patterns. See our guide on how accurately smartwatches track sleep stages.
- Resting heart rate (RHR): A gradually rising RHR is expected in pregnancy; a watch that charts the trend over weeks is more useful than any single reading.
- Comfort and fit: Lighter cases and soft bands matter as wrists and fingers swell later in pregnancy.
- Battery life: Overnight tracking is only useful if the watch survives the night. Compare options in our battery life roundup.
- Gentle activity tracking: Reminders to move, breathe, and log light walks support the kind of moderate activity many providers encourage.
Best smartwatches for pregnancy tracking, compared
The table below summarizes official manufacturer specifications and the features most relevant to rest and wellness during pregnancy. Health features vary by region and may require setup or a companion app.
| Model | Best for | Sleep tracking | Battery (official) | Notable wellness features |
|---|---|---|---|---|
| Apple Watch Series 10 | iPhone users | Sleep stages & sleep schedule | Up to ~18 hrs (36 in Low Power) | Heart rate notifications, ECG app, Cycle Tracking, Mindfulness |
| Samsung Galaxy Watch7 | Android users | Sleep stages & Sleep Coaching | Up to ~30 hrs (40 power saving) | BioActive sensor, stress tracking, Cycle Tracking |
| Garmin Venu 3 | Multi-day battery | Sleep stages & Sleep Score | Up to ~14 days | Body Battery, HRV status, stress & respiration tracking |
| Fitbit Sense 2 / Charge 6 | Simple wellness & comfort | Sleep stages & Sleep Score | Up to ~6 days | Stress management, resting heart rate trends, guided breathing |
How to use a smartwatch well during pregnancy
A wearable is most helpful when you treat it as a trend journal, not a verdict. A simple routine keeps the data meaningful without becoming a source of anxiety.
Battery habits help you keep that overnight streak going; our tips on improving smartwatch battery life are worth a look if your watch struggles to last until morning.
Apple Watch vs. Garmin for pregnancy
The most common decision is between a feature-rich smartwatch and a battery-focused one. Neither is “more accurate” for pregnancy—the trade-off is convenience versus endurance.
- Deep iPhone integration and app ecosystem
- Nightly charging required
- Up to two weeks of battery for uninterrupted sleep data
- Body Battery and HRV framing for recovery
What smartwatches cannot do
This is the most important section. Consumer wearables are not medical devices for pregnancy monitoring, and treating them as such can be misleading or stressful.
- SpO2 is not fetal oxygen. Wrist pulse oximetry measures your blood, with real limits—see what SpO2 measures and how accurate it is.
- Blood pressure features are limited. Preeclampsia screening relies on a validated cuff, not a watch, as we explain in can a smartwatch measure blood pressure accurately.
- ECG has caveats. An on-watch ECG checks for signs of atrial fibrillation in adults and is not designed around pregnancy.
Frequently asked questions
Can a smartwatch track my baby’s heartbeat?
No. Smartwatches measure heart rate at your wrist and cannot detect or track a fetal heartbeat. Fetal heart monitoring requires clinical tools like a Doppler or ultrasound used by a trained professional.
Is it safe to wear a smartwatch while pregnant?
Smartwatches use low-power Bluetooth and, on some models, optical sensors that shine light on the skin—technologies widely considered low-risk. We cover the science in do smartwatches emit harmful radiation. If you have concerns, ask your healthcare provider.
Which pregnancy metrics are worth watching?
Resting heart rate trends, sleep duration and consistency, and general activity are the most useful. Focus on multi-week patterns rather than individual readings, and share anything that feels off with your care team.
Do I need a cellular smartwatch during pregnancy?
Not necessarily. LTE can be reassuring for walks or leaving your phone behind, but Wi-Fi and Bluetooth models handle wellness tracking fine—see LTE vs. Wi-Fi.
Who should buy which
If you use an iPhone and want the smoothest experience, the Apple Watch Series 10 is the natural pick. Android users are best served by the Galaxy Watch7. If overnight battery and detailed sleep and recovery data matter most, the Garmin Venu 3—or a comfortable, budget-friendly Fitbit—is the smarter choice.
