What’s the Best Alternative to Fitbit for Sleep Tracking? 

  • The RISE app is the best alternative to Fitbit for sleep tracking as it works out how much sleep you personally need and focuses on sleep debt and circadian alignment: the two metrics that, when improved, are proven to make the biggest difference to how you feel each day.
  • RISE gives you daily advice, tailored to your body, to improve your sleep, energy, health, performance, and productivity. 
  • You don’t need a wearable to use RISE, but if you have one, you can sync RISE with Garmin, Apple Watch, and Oura Ring directly and devices like Whoop and Eight Sleep indirectly through Apple Healthkit. If you’re still considering Fitbit, RISE syncs with that, too.

Fitbit devices are great for fitness tracking — the clue is in the name — but they’re not the best option when it comes to tracking sleep. 

There are plenty of other wearable devices to consider, but if you want to make a real difference to your nights and days, the best sleep tracker isn’t a wearable at all — it’s an app. 

Enter, RISE. 

The RISE app works out how much sleep you need and gives you daily personalized guidance to help you lower your sleep debt (how much sleep you owe your body) and get in circadian alignment (or stay in sync with your circadian rhythm, or body clock). 

Below, we share more on why RISE is the best Fitbit alternative for sleep tracking. 

Buyer’s Guide: How to Choose a Sleep Tracker

These questions will help you narrow down your search for a sleep tracker:

  • Does the sleep tracker focus on the right metrics? If you want more sleep and energy, you need to focus on your sleep debt and circadian alignment. Many sleep trackers don’t give you any information about them, or they do so inaccurately.
  • RISE uses sleep science algorithms to give you accurate information about your sleep debt and circadian rhythm. You’ll see these insights front and center in the app.
  • Does the sleep tracker help you improve those metrics? Look for a sleep tracker that gives you guidance on how to improve your sleep debt and circadian alignment, so you notice the difference in your sleep and energy levels.
  • RISE gives you advice tailored to how much sleep you personally need, how much sleep debt you have, and your circadian rhythm each day. Follow this guidance to lower your sleep debt, get in sync with your circadian rhythm, and feel the benefits in your daily life. Sleep tracker prices vary a lot. Compare prices, subscription models, and free trial periods to find the best value for money.
  • Does the sleep tracker come with useful features? Depending on what you want from a sleep tracker, consider features like sleep sounds, a smart alarm, heart rate tracking, or workout tracking.
  • RISE has sleep sounds, a smart alarm, suggested sleep times, and personalized sleep hygiene notifications — all features designed to help improve your sleep and energy levels.
  • How much does the sleep tracker cost? When considering if the price is worth it, think about how much you’d pay for more energy and productivity each day. Look for hidden costs and whether you need to buy a wearable device to make a tracker work.
  • RISE costs $69.99 a year, which works out to $5.83 a month. There’s a seven-day free trial during which you can find out how much sleep you need and try all of the app’s features.
  • Does the sleep tracker have good reviews? Compare user reviews and look out for industry awards and recognitions.
  • RISE has been named one of the best sleep apps for 2024 and has thousands of 5-star reviews from users.
  • Does the sleep tracker need a wearable to work? You’ll need to wear a wearable to bed to get Fitbit’s sleep-tracking data — the same goes for trackers like Whoop, Apple Watch, and Oura Ring. Consider the extra cost, battery life, and how comfortable a gadget will be to sleep with.
  • You don’t need a wearable to use RISE. The app can track your sleep through your phone. If you have a wearable, RISE can pull data from it.

Metrics to Track for Better Sleep and More Energy 

Here’s how RISE and other Fitbit alternatives compare on common sleep tracking features. 

Sleep Debt

Sleep debt is the amount of sleep you owe your body. The lower your sleep debt, the better your energy levels, mood, health, and productivity. 

Sleep debt is one of the most important metrics to track if you want more energy. But many tracking devices and apps — including Sleep Cycle, Oura Ring, and Whoop — either don’t track sleep debt or they use self-set sleep goals or generic sleep guidelines to work it out. This makes the data most likely inaccurate. Fitbit doesn’t track sleep debt, and it calculates sleep data in general by using a self-set sleep goal. 

RISE is different. 

RISE calculates your sleep debt by working out your sleep need — this is how much sleep you personally need. The app uses a year’s worth of your phone use behavior and sleep science algorithms to do this. 

Generic guidelines don’t cut it as everyone’s sleep need is different. 

When we looked at the sleep needs of 1.95 million RISE users aged 24 and up, we found they ranged from five hours to 11 hours 30 minutes. 

The RISE app can tell you how much sleep you need.
RISE users’ sleep needs.

To work out sleep debt, RISE compares how much sleep you need to how much sleep you get. 

RISE uses one of three methods to track your sleep duration: 

  • Tappigraphy: Phone use, which can be more accurate than tracking body movement for some sleepers.
  • Acoustic sleep monitoring: Using your phone's microphone to track sound.
  • Mattress-based actigraphy: Using your phone’s accelerometer to track movement. 
  • Data from a wearable (if you have one): RISE syncs with Apple Watch, Garmin, Fitbit, or Oura Ring. If you forget to wear or charge your wearable, RISE will automatically use tappigraphy to track your sleep.

RISE calculates your sleep debt over the course of 14 nights and gives you one clear number to focus on.

We dive into the best sleep debt trackers here.

Circadian Alignment 

Circadian alignment is when your circadian rhythm is in sync with the light-dark cycle. Your circadian rhythm is your internal body clock that dictates your sleep schedule and energy levels across the day. 

Syncing up with it can help you get enough sleep and it’ll boost your energy, productivity, and physical and mental health independent from sleep. 

Many sleep apps and trackers — like Sleep Cycle — don’t give you any information about your circadian rhythm. 

Others — like Fitbit, Whoop, AutoSleep, and Oura Ring — give you some insights into your circadian rhythm with recommended sleep times and sleep consistency scores (how regular your sleep patterns are). 

RISE takes this one step further and gives you insights you can use all day and night. 

RISE predicts the timing of your circadian rhythm each day using your recent sleep times, inferred light exposure, and algorithms built on the SAFTE model, which was developed by the US Department of Transportation and the Department of Defense.

You’ll see: 

  • When your body naturally wants to wake up and go to sleep 
  • When your energy levels will rise and fall across the day 
  • The best time to do your most challenging tasks, take a break, take a nap, work out, and wind down for bed 

We explain how RISE works out your circadian rhythm here.

Time Spent in Sleep Stages

Many sleep monitors tell you the amount of time you spend in light sleep, deep sleep, and REM sleep. That includes Apple Watch, Garmin, Whoop, and Samsung Galaxy watch. Fitbit estimates the amount of time you spend in different sleep stages based on your movement and heart rate patterns.

RISE doesn’t track the amount of time you spend in different sleep stages. Although, if you’re interested in this data and have an Apple Watch, RISE can pull sleep stage data from your smartwatch to the RISE app so you can view it in the app alongside RISE’s sleep tracking. 

But here’s why RISE doesn’t track sleep stages.

Firstly, how much time you spend in each sleep stage doesn’t really affect how you feel day to day. There are no recommended amounts to aim for and, in reality, we all need a different amount of each sleep stage, which changes nightly for a variety of reasons. 

Plus, research shows sleep trackers — including Fitbit and other wearables — aren’t entirely accurate at working out which sleep stage you’re in. Even sleep experts disagree sometimes — in polysomnography (sleep studies), experts agree on results only about 80% of the time. 

Instead of worrying about sleep stages, focus on getting enough sleep on a regular schedule — another reason low sleep debt and circadian alignment are so important — as this will ensure you get enough of each sleep stage.

Sleep Quality

Sleep quality is another common metric. You’ll find it tracked by Garmin, Apple Watch, AutoSleep, Sleep++, and the Withings sleep mat, among others. 

Fitbit gives you a sleep score based on your heart rate, sleep stages, and time spent awake in bed. With Fitbit Premium, you’ll get monthly sleep analysis based on 10 metrics, like deep sleep and sleep start time.

RISE doesn’t track sleep quality itself, but there’s a good reason for that.  

Firstly, there’s no set definition for sleep quality. Sleep tracking apps and devices often give you a sleep score based on their own scoring system that includes multiple metrics. This score probably won’t impact how you feel during the day (placebo effects aside) because it’s made up of so many metrics, it’s hard to improve it, even if it did make a difference. 

How you feel about your sleep can make a difference to your well-being, however, so you can self-rate your sleep quality in RISE.

Heads-up: Looking to diagnose a sleep disorder? Your best bet is to speak with your doctor or a sleep specialist. Metrics like sleep quality or the amount of time spent in certain sleep stages can’t help. Sleep debt can be useful to highlight sleep loss. Some sleep trackers, like Apple Watch, track your blood oxygen levels, and others, like Fitbit, can detect snoring. These features can help a doctor detect signs of sleep apnea.

Which Sleep Trackers Help You Get More Sleep and Energy? 

If you’re looking for an alternative to Fitbit for sleep, you’re probably looking to get more sleep and energy. In that case, look for features that help you lower your sleep debt and get in circadian alignment — the two metrics that, when improved, make the biggest difference to how you feel. 

Many sleep trackers don’t help you improve these metrics, or they only partially do with limited features like bedtime consistency tracking or manually tracking behaviors that might impact your sleep. You’ll find these features in trackers like Whoop, AutoSleep, and Fitbit. 

Here’s how RISE helps: 

  • 20+ sleep hygiene notifications: Find out the best time to do the sleep habits that help you fall asleep faster and wake up less often. You’ll learn when to have your final coffee each day, when to get and avoid bright light, and when to stop eating each day.
  • Recommended sleep and wake times: See when your body naturally wants to sleep and wake up or get a personalized bedtime based on your sleep need, chosen wake time, and sleep debt. This bedtime will slowly shift earlier to help you get used to sleeping more.
  • A prediction of your energy levels: See when your energy will most likely rise and fall each day and schedule your tasks to match, boosting productivity.
  • Sleep sounds and guided relaxation exercises: Unwind and fall asleep faster with guided exercises and a selection of soothing sounds. 
  • A smart alarm clock: As you’re setting your alarm in RISE, you’ll see if your wake time will add to sleep debt. Come morning, get woken up with soft sounds or vibrations.

Other Useful Features

The list of Fitbit alternatives is long, so deciding which other features you’re looking for in a tracker can help you narrow it down. 

Other features to consider include snore detection, heart rate monitoring, and tracking of your heart rate variability (HRV), blood oxygen saturation (SpO2), body temperature, and stress levels. You can also get activity tracking, which comes with many fitness trackers like Fitbit, Whoop, Oura Ring, Garmin, and Apple Watch.

RISE offers unique features to improve your sleep and energy like: 

  • Partner Connect: Sync up with a partner or friend to view each other's sleep debt. Know when to go easy on each other and when they need a gentle nudge to stay on track.  
  • Calendar integration: See your daily energy peaks and dips in your calendar, so you never miss your most productive times or schedule important meetings during your afternoon slump
  • See RISE insights on other devices: Access RISE on the app, the iPhone home screen widget, or on your Apple Watch or iPad.
  • Sync with wearables and sleep apps: RISE syncs with Apple Watch, Garmin, and Oura Ring directly, devices like Eight Sleep Mattress and Whoop indirectly through Apple HealthKit, and with apps like Sleep Cycle and AutoSleep. And if you do decide to get a Fitbit, RISE can sync with that, too.

We can’t compare reviews for every Fitbit alternative out there. But here’s what RISE users have to say: 

  • “This app has changed my life. I never realized how much sleep I actually needed, and how sleep loss accumulates to detrimental effect. Since I got my debt under control, I have more energy, am no longer crashing or napping, drinking less coffee, and my days feel more productive. If you think this app is expensive, it’s really not, for what you get in return.” Read the review

And here’s what users have to say about using RISE and Fitbit together: 

  • “After the first two days of using this app, I already felt a significant boost in my energy! No more falling asleep in class! I also love seeing my energy levels because they are actually freakishly accurate. I also love that I can import my Fitbit data.” Read the review.
  • “The RISE app has been very helpful with managing my sleep habits and energy schedule. The seven-day trial alone has been a significant help. The support team is very responsive and helpful if you have any questions. I love the integration with Fitbit and Google Fit smart devices.” Read the review.

Beyond happy users, RISE has recognition from some big names in the sleep industry. 

Sleep Foundation and Sleep Doctor both named RISE one of the best sleep apps for 2024. And Apple nominated RISE for a design award and named it an Editor’s Choice app.
