We’ve found that it’s one of the most comfortable and accurate ways to track your bedtime. We’ve provided detailed summaries of our testing further down this guide. However, for those just getting to grips with the various sleep trackers available, below is a quick summary.
Sleep Tracking & Smart Alarm Apps
It continuously monitors your heart rate, respiratory rate, and heart rate variability (HRV) to provide insights into sleep quality. It excels in tracking overall sleep performance and recovery, offering valuable data for athletes and health-conscious individuals. However, it provides an average HRV for the night rather than a detailed graph throughout the night, which some competitors like is mad muscles safe the Oura Ring do better. Sleep tracking apps use data from wearable devices like fitness trackers that monitor movement, heart rate, and breathing patterns throughout the night.
Build the future of health
Compared to competitors, the Oura Ring app is similarly polished, offering sleek visuals and robust insights into sleep stages and recovery, with an emphasis on simplicity. Fitbit’s app also provides a user-friendly experience, with colorful charts and accessible breakdowns of sleep, activity, and health metrics. However, WHOOP excels in giving personalized coaching tips and deeper data interpretation, particularly for athletes and performance-oriented users, which may be more advanced than what Fitbit or Garmin offers in their apps. Note that some of the more science-heavy metrics, like menstrual cycle tracking, are only accessible via the Fitbit app, which comes pre-installed on the Pixel Watch. As well as my deep sleep, REM sleep, wake-up times, skin temperature, heart rate, blood oxygen.
- Log meals, caffeine, and alcohol intake to identify how diet choices impact your sleep onset and quality throughout the night.
- There was a nonsignificant trend for EarlySense Live to underestimate REM latency, while the other five devices all significantly overestimated REM latency.
- Sleep tracking apps are mobile applications that monitor your sleep patterns by collecting data on the different stages of your sleep cycle, such as light sleep, deep sleep, and REM (rapid eye movement) sleep.
- The combination of hardware sensors and advanced software algorithms provides comprehensive sleep insights that rival medical-grade equipment.
- I don’t really get any added value from having dropped another $400 for the new one.
- We’re all different in terms of when we do our best work, best workouts, and best sleep.
Apple Watch Sleep Stages

If you believe you may have sleep apnea, make an appointment with your doctor to discuss the next steps. The authors declare no financial or nonfinancial conflicts of interest. Additionally, none of the authors have any conflicts of interest related to the companies whose devices were evaluated in the study. All devices that differed in WASO from PSG did so whether calculated from SOL or LPS, indicating negligible differences in WASO between the two sleep latency thresholds. Further, all devices except the Fatigue Science Readiband and ResMed S+ had significant levels of proportional bias for WASO, from either one or both sleep latency measures.
Whoop vs. RISE Sleep App: Which Sleep Tracker Is Best?
These devices do similarish things — provide insight into your overall health by tracking your sleep, vitals, and workouts — but that is just scratching the surface. Even so, I was intimidated when I first started using these devices since there was a lot of data to digest, so I spent almost two months testing them out. I wore them around the clock (as recommended), to the office, to strength training and SoulCycle classes, on my daily walks, to bars and restaurants, and to bed. On a final note, there is a reason why lots of people love their Apple Watches. There are many more options and ways to use the Apple Watch compared to the Whoop and Oura – including triaging your email, voice responding to texts, and acting as an actual watch. The Apple Watch feels like an extension of your phone, first and foremost, an activity tracker, second – and only with extra apps – and a sleep tracker as more of an afterthought.
Statistical analysis
The best sleep tracking apps and devices for you will depend on your specific needs and preferences. The combination of Apple Watch Series 9 and Sleep++ app provides one of the most comprehensive and user-friendly sleep tracking experiences available. Our four-month testing period revealed impressive capabilities that rival dedicated sleep tracking devices. Through rigorous testing of Fitbit’s latest sleep tracking capabilities, we’ve found their 2026 sleep analysis tools to be substantially improved over previous versions.
Play soothing audio directly in the app to help you fall asleep faster and stay asleep longer. Log meals, caffeine, and alcohol intake to identify how diet choices impact your sleep onset and quality throughout the night. Track room temperature, noise levels, light exposure, and other environmental factors affecting your sleep. You have the ability to administer custom-built health and wellness questionnaires that athletes can answer on their smartphone or on the Weight Room View app. Early awareness can prevent long-term health problems and improve daily functioning.
Apple Watch Readiness Score
We also access the advice the product gives when it comes to improving sleep. Accuracy is impressive, though; your ear is an excellent place for an optical heart rate sensor as it’s less susceptible to light leakage, and blood circulation isn’t going to be disturbed by your sleeping position. This systematic approach helps ensure you’re getting meaningful data from your sleep tracking apps and devices while avoiding common pitfalls that can lead to inaccurate conclusions. Understanding how to properly use sleep tracking apps and devices can significantly improve their effectiveness. Through years of testing and working with users, I’ve developed specific strategies to maximize the benefits of these tools.
Best wearable sleep tracker
Tracking macros, calories, and hydration is crucial for hitting fitness goals, but logging and analyzing it daily can be tedious. With Garmin Chat Desktop, you can query your nutrition data from Garmin’s ecosystem (integrated with tools like MyFitnessPal) and get breakdowns that guide your meal choices. Timeshifter uses the latest in circadian neuroscience to create a personalized plan to help you conquer jet lag. By giving you simple, timed instructions on when to seek or avoid light, when to sleep, and when to use caffeine, it helps you rapidly adjust to a new time zone.

Whoop also provides weekly and monthly reports correlating your journal data, activity data and sleep data so that you can see the trends and make changes to improve your sleep and recovery. If your sleep tracking device also shows when you get those hours – even better. You should see that you spend less time in REM phases early in the night and have longer REM cycles towards the end of the night (early morning). The best sleep apnea apps provide valuable insights into your sleep patterns, but it’s important to remember that they cannot replace a sleep apnea test. Most devices (Fatigue Science Readiband, Fitbit Alta HR, EarlySense Live, ResMed S+, SleepScore Max) performed as well as or better than actigraphy on sleep/wake performance measures, while the Garmin devices performed worse. Overall, epoch-by-epoch sensitivity was high (all ≥0.93), specificity was low-to-medium (0.18–0.54), sleep stage comparisons were mixed, and devices tended to perform worse on nights with poorer/disrupted sleep.
