Garmin and Fitbit are among the most popular smartwatch makers in the world. But they have different approaches, trying to satisfy different tastes and needs. 

Garmin has traditionally focused more on exercise tracking, while Fitbit offers comprehensive devices that match most lifestyles. 

However, the question is which one is better for sleep tracking and helps maintain a healthier sleep routine. Read on to find out.

Comparing Garmin and Fitbit for Sleep Tracking

To compare Garmin and Fitbit, we need to consider different aspects and features, including sleep insights, accuracy, tracking midday sleep and naps, and smart alarm.

Sleep Insights

The apps by both companies provide the following information:

  • How long you’ve slept each night.
  • Timeline of your light, deep, or rapid eye movement (REM) sleep.
  • Sleep score.
  • Sleeping heart rate.
  • Seven-day view of your sleep.
  • Respiration rate.

Information that Fitbit provides but Garmin doesn’t:

  • Blood oxygen variation.
  • Comparison of your target sleep plan with your actual schedule.
  • 30-Day average time spent in each sleep stage.
  • Comparison of your sleep patterns with other people of similar age and gender.

Information that Garmin provides but Fitbit doesn’t:

  • A timeline of your movements.
  • Average blood oxygen levels.

Verdict

As you can see, Fitbit offers more insightful and broader information about your sleep than Garmin. And note that some of this information, like sleep score, is only available on high-end Garmin watches, whereas Fitbit offers them for most of its devices.

Another issue is that most Garmin watches don’t show your sleep information on the device itself; you can only see them on your mobile phone or laptop. But Fitbit provides some sleep-related stats on the small screen as well. 

Accuracy

To see how accurate Garmin and Fitbit are, let’s examine the results of two different studies done on Garmin Vivosmart 3 and Fitbit Charge 2.

The first study by Garmin Health shows that Garmin Vivosmart 3 is about 96 percent accurate in detecting sleep, while only around 73 percent accurate in detecting awake.

The second study by researchers at the Center for Health Sciences shows that Fitbit Charge 2 is 96 percent accurate in detecting sleep but only 61 percent accurate in detecting when you’re awake.

According to the first study, the Garmin watch can detect the three sleep stages with about 70 percent accuracy. On the other hand, the Fitbit model has 81, 49, and 74 percent accuracy in detecting light, deep, and REM sleep stages, respectively.

Verdict

Both Garmin and Fitbit are pretty accurate in tracking your overall sleep patterns. But when it comes to differentiating between sleep stages, Garmin seems to be more consistent—although both brands have much more work to do. 

Tracking Naps

Garmin users often complain that their devices can’t monitor mid-day naps. Garmin still hasn’t addressed this request. So, if that’s important for you, you might want to consider one of Fitbit’s watches.

Smart Alarm

The smart alarm is a feature that sets off the alarm during your light sleep, so you don’t wake up grumpy. Garmin doesn’t offer the feature, but it’s included in Fitbit models like Charge 4 and Ionic

Has Garmin Improved Sleep Tracking?

Until recent years Garmin was way behind Fitbit in sleep tracking. But since introducing the Advanced Sleep Monitoring feature, the company has significantly enhanced its sleep tracking. With this feature, Garmin offers more helpful information in a more user-friendly way.

Garmin also uses sleep data for a feature called Body Battery, which essentially shows an estimation of your energy level based on your heart rate variability, stress, activity, and rest data.

Final Verdict

Overall, Fitbit outperforms Garmin in terms of sleep tracking with broader insights, more focus on sleep, and a more user-friendly app.

If you don’t care much about features like a smart alarm or nap tracking and generally prioritize exercise-tracking over sleep-tracking, Garmin is also a good choice. 

On the other hand, if you’re looking for a device that monitors your lifestyle holistically, not just your training, and provides better sleep insights, then you better go with Fitbit.
