What You'll Learn
Fitbit Alta HR has advanced sleep tracking functions
The Fitbit Alta HR has advanced sleep-tracking functions that monitor your sleep patterns and provide insights to help you improve your sleep quality. One of its key features is the Sleep Stages function, which allows the device to detect light, deep, and REM stages of sleep. This goes beyond simply tracking the number of times you wake up at night, the amount of time spent awake, and the times you fall asleep and wake up. By understanding your sleep stages, the Alta HR can provide you with more detailed information about your sleep habits.
Additionally, the Alta HR incorporates heart-rate data into its sleep-tracking algorithms. It constantly monitors your pulse, even while you sleep, to provide insights into your sleep state. This heart-rate data is used to deliver more accurate calorie-burn estimates during the day and give you information about your cardiovascular health. The continuous heart rate reading can also tell you how hard you're working during exercise and which heart rate zone you're training in.
The Alta HR also includes Sleep Insights, which offers personalized advice and information about your sleep. Over time, the device learns your habits, sleep patterns, and activities, tailoring its suggestions to help you improve your sleep. Each morning, you'll receive a message within the app, encouraging you to meet your sleep goals or congratulating you on achieving them.
The Alta HR's sleep-tracking capabilities are designed to provide a more comprehensive understanding of your sleep patterns and offer guidance to help you optimize your sleep quality. Its combination of sleep stage monitoring, heart rate data, and personalized insights make it a valuable tool for those seeking to improve their sleep habits and overall well-being.

Alta HR has a heart rate monitor to estimate sleep state
The Fitbit Alta HR is an updated version of the original Alta, with a few design differences and improved sleep-tracking features. The Alta HR has a heart rate monitor that constantly keeps tabs on your pulse and uses this data to estimate your sleep state. This is a significant improvement on the original Alta, which lacked heart rate sensors.
The heart rate monitor on the Alta HR works all day and measures your pulse throughout the night and your resting heart rate before you wake up. The continuous heart rate data, along with heart rate variability data and the accelerometer's movement information, provides a clearer and more accurate picture of your night's sleep. The Alta HR can estimate the amount of time spent in light, deep, and REM sleep, as well as the periods when you're awake at night.
The Sleep Stages and Sleep Insights features in the Fitbit app use the heart rate data gathered throughout the night to provide a deeper analysis of your sleep. The app can offer insights and education on how to improve your sleep based on your nightly performance. Over time, the Fitbit system is supposed to learn your habits, sleep patterns, and activities, tailoring its advice to your specific needs.
While the Alta HR's sleep-tracking features generally work as promised, the accuracy of the data is difficult to verify independently. Some studies have shown that the Fitbit Alta HR provides reasonably accurate estimates of sleep stages, with accuracies ranging from 0.69 to 0.81 for light sleep, 0.36 to 0.89 for deep sleep, and 0.62 to 0.89 for REM sleep.

Fitbit Alta automatically tracks sleep with movement and heart rate data
The Fitbit Alta HR is a slim, fitness-tracking wristband that can automatically track your sleep. It uses a combination of movement and heart rate data to do so.
The Alta HR is an upgraded version of the original Fitbit Alta, which lacked a heart rate monitor. The Alta HR's heart rate monitor constantly keeps tabs on your pulse, allowing it to estimate what sleep state you're in. It can monitor light, deep, and REM sleep stages by tracking beat-to-beat changes in your heart rate, known as heart rate variability (HRV).
Fitbit's sleep-tracking feature works by assuming you are asleep when there is no movement detected for about an hour. It then confirms this by measuring small movements, such as rolling over in your sleep. If the device has a heart rate monitor, like the Alta HR, it combines heart rate and movement data to develop a more accurate picture of your sleep.
The Alta HR's sleep tracking feature provides insights and education on how to improve your sleep based on your nightly performance. Over time, the Fitbit system learns your habits, sleep patterns, and activities, tailoring its advice to your specific needs. You can review your sleep data through the Fitbit app, which displays your total sleep time for the previous night, excluding any time you were restless or woke up.
While the Alta HR offers advanced sleep tracking capabilities, it is important to note that sleep tracking devices may have limitations in terms of accuracy, especially for individuals with disrupted sleep or sleep disorders.

Fitbit Alta's sleep tracking has generic tips and encouragement
The Fitbit Alta HR is a successful follow-up to its predecessor, thanks to its new heart rate sensor. It's also one of the more full-featured general-purpose fitness and sleep trackers on the market. The Alta HR improves on the original, with a new heart rate monitor that constantly keeps tabs on your pulse. A software update that arrives on the Fitbit app provides deeper analysis of how you're sleeping. The Alta HR delves deeper into sleep analysis than other fitness trackers. While most other devices use just accelerometer data and an algorithm to figure out when you're asleep, the Alta HR also taps your heart rate variability as a source of information. This lets Fitbit estimate what stage of sleep you're in (REM, deep or light) and track how long you stay in each phase.
The Alta HR's sleep stage-tracking tool works, providing a detailed sine-like wave graph of the user's time in bed. Below that is a bar chart that breaks down the exact duration in each zone. However, the sleep tracking can be inconsistent, with one reviewer noting that they were disappointed to find that their sleep-tracking chart for the night didn't include any sleep stage information, only movement-based data about how long they had been awake, restless and asleep.
The Fitbit Alta HR provides generic tips and encouragement for better sleep. Based on each night's performance, the app offers encouragement and education on how to get better sleep. Over time, Fitbit's system is supposed to learn your habits, sleep patterns and activities, and tailor its advice accordingly. Each morning, the app sends a message congratulating the user on meeting their sleep goal or encouraging them to work towards that milestone.
The Alta HR also has a silent alarm, which vibrates on the user's wrist at the specified time. This is useful if you have a different waking time to your partner. However, some people have found that the level of vibration isn't strong enough to wake them from their slumber.

Fitbit Alta's sleep tracking accuracy is questionable
The Fitbit Alta HR is geared towards the basics: keeping tabs on the steps you take during the day, distance covered, and calories burned. It also has a Tap Display, a pseudo-touchscreen that uses an accelerometer to tell when you're jabbing at the panel. The Alta HR sports a new heart rate monitor that constantly keeps tabs on your pulse, which can now be used to deliver more accurate calorie-burn estimates.
The Alta HR also has a sleep-tracking feature that works well most of the time. The device delves deeper into sleep analysis by incorporating your heart-rate data into its algorithms to estimate what sleep state you're in. The app also offers encouragement and education on how to get better sleep. Over time, the Fitbit system is supposed to learn your habits, sleep patterns, and activities, and tailor its advice to what it knows you're doing. However, its accuracy is hard to verify. One review found that the Alta HR's sleep-tracking feature was proven to be one of the most accurate and insightful. Another review found that the Alta HR's sleep-tracking feature was only accurate when set to normal mode, which only scores significant body movements while in bed as awake time. When set to sensitive mode, the device gave notably higher bias in estimating sleep metrics and lower accuracy.
