What You'll Learn
Fitbit Alta HR's Sleep Stages tech
The Alta HR automatically recognizes when you fall asleep and wakes up, and it will provide your Sleep Stages for a regular night's sleep. The Sleep Stages interface makes it easy to see how your body moves between each sleep phase throughout the night. It's plotted on a line graph against time, making it easier to decipher. The time spent in each sleep phase is also benchmarked against the average for people of your age and gender.
The Sleep Insights feature provides advice or observations based on your sleep "performance". For example, it might commend you for keeping a regular sleep schedule or suggest changing your sleep environment if you're not sleeping well. However, the insights are often very short and provide only a top-level overview.
While the Alta HR's sleep tracking technology is a step forward, some experts have expressed concerns about the accuracy of sleep-tracking fitness devices. They want to see more research to support Fitbit's claims and believe that fitness trackers depend too heavily on user movement to determine sleep levels.

Fitbit Alta's accuracy
The Fitbit Alta HR is geared towards the basics of fitness tracking, such as keeping track of the steps taken, distance covered, and calories burned. It also provides a breakdown of the impact of your workout on your day, including steps contributed, calories burned, and active minutes. The Alta HR is not ideal for those looking for a fitness tracker as an exercise companion. However, its sleep-tracking capabilities are noteworthy.
Fitbit's sleep-tracking technology, developed in collaboration with sleep scientists, claims to provide more accurate estimates of the time spent in light, deep, and REM sleep. The Alta HR uses heart rate monitoring to make assumptions about sleep stages and duration. The Sleep Stages interface allows users to visualize their sleep patterns, with data plotted on a line graph against time. This makes it easier to understand sleep patterns and identify disturbances.
While Fitbit's sleep tracking has been praised as a step forward for wrist-based sleep tracking, some experts have expressed concerns about the accuracy of sleep-tracking devices in general. The University of Washington's Dr. Nathaniel Watson, a sleep specialist, stated that while it's plausible to design a device to track sleep stages accurately, he has yet to see one that does so convincingly. He emphasized the need for companies like Fitbit to provide research to support their claims.
The Alta HR's sleep tracking has been found to have some quirks. For example, it may record lounging or charging periods as sleep, and it only provides Sleep Stages data for regular night sleep, excluding naps. Additionally, while the Sleep Insights feature provides advice and observations based on sleep performance, the insights are often brief and lack detailed coaching.
In conclusion, while the Fitbit Alta HR offers basic fitness tracking features, its sleep-tracking capabilities have received mixed reviews. It provides valuable insights into sleep patterns, but its accuracy has been questioned by experts, and there are some limitations to its sleep-tracking functionality. Further improvements and expansions to its sleep-tracking features are expected.

Fitbit Alta's silent alarm
The Fitbit Alta HR is a useful and valuable sleep tracker. It has a silent alarm feature that vibrates on your wrist at the specified time. This is handy if you have a different waking time than your partner. While the silent alarms have been found to work just fine, some people have reported that the level of vibration is not strong enough to wake them up from their slumber.
The Alta HR's sleep tracking capabilities are enhanced by its heart rate monitor, which allows it to deliver more accurate calorie-burn estimates and provide information on your resting heart rate, a good indicator of your overall cardiovascular health. The heart rate monitor also provides continuous heart rate readings during exercise, indicating how hard you are working and which heart rate zone you are training in.
Fitbit's Sleep Stages technology, available on the Alta HR, provides insights into the different phases of sleep, such as light sleep, deep sleep, and REM sleep. It presents this information in an easy-to-understand line graph, allowing you to see how your body moves between each phase throughout the night. Additionally, the time spent in each phase is benchmarked against averages for people of the same age and gender.
While Fitbit's sleep tracking technology has received praise, some experts have expressed concerns about the accuracy of sleep-tracking devices in general. They point out that these devices rely heavily on movement and heart rate to determine sleep levels, and there is a lack of transparency in their algorithms. Fitbit's Sleep Insights feature provides advice and observations based on your sleep performance, but some users have expressed a desire for more detailed and personalized coaching to improve their sleep.

Fitbit Alta's heart rate monitoring
The Fitbit Alta HR is an activity and sleep-tracking device that provides continuous heart rate monitoring. The heart rate monitor delivers your resting heart rate, which is a good indicator of your overall cardiovascular health. The fitter you get, the lower this number will be as your cardiovascular system becomes more efficient. The Fitbit Alta HR also provides continuous heart rate reading during exercise, which can tell you how hard you're working and in which heart rate zone you're training.
The Fitbit Alta HR's heart rate monitor is also used to deliver more accurate calorie-burn estimates. The device provides a breakdown of the impact of your exercise on your day in terms of steps, calories burned, and active minutes. However, it does not provide any extra running information, such as the estimated distance covered. The automatic exercise tracking feature is basic and on par with other devices like the Fitbit Flex 2.
The Fitbit Alta HR's heart rate monitoring capabilities are combined with its sleep-tracking features. The device's Sleep Stages interface allows users to see how their body moves between each sleep phase throughout the night, plotted on a line graph against time. This information is benchmarked against the average for people of the same age and gender, providing context for the user's sleep data.
While the Fitbit Alta HR provides insights into sleep patterns, there are some limitations to its heart rate monitoring capabilities. The device may occasionally misinterpret certain activities as sleep, such as lying on the couch or leaving the device on the bed while charging. Additionally, while the device can record naps, it only provides Sleep Stages information for a regular night's sleep.
