Best Sleep Apps in 2026, by Evidence

Last verified November 2, 2026. Every grade, FDA status and price on this page links to the source we checked. Where we couldn't confirm something, we say so.

We have not run our own sleep-lab tests on these apps; evidence and accuracy figures come from the studies cited below.

The short answer

If you have chronic insomnia, the app category with real evidence is digital cognitive behavioural therapy for insomnia (CBT-I). A 2020 meta-analysis of 33 randomised trials found it cut insomnia severity by about 5 points on the 28-point Insomnia Severity Index, with benefits still there a year later². Two CBT-I programs are FDA-cleared as prescription devices (SleepioRx and Somryst)^{4, 6}, and the VA's CBT-i Coach is free⁹. Meditation apps such as Calm have one decent trial for pre-sleep arousal and daytime fatigue¹⁰. White-noise apps have very low-certainty evidence¹². Sleep trackers measure sleep less accurately than they look, especially in people who sleep badly¹³. Most people need one app, not five.

Status snapshot: what FDA has reviewed

Almost every sleep app is sold as a "wellness" product with no FDA review. Two insomnia programs are different: they went through 510(k) clearance as computerized behavioral therapy devices for insomnia (product code QVO).

App	FDA status	Who it's for	How you get it
SleepioRx (Big Health)	510(k) K233577, cleared August 5, 20244	Adults 18+ with chronic insomnia, as an add-on to usual care5	Prescription from a licensed clinician5
Somryst (now owned by Nox Health)	510(k) K191716, cleared March 23, 20206	Adults 22+ with chronic insomnia7	Prescription; Nox sells it through employers, health plans and health systems7
CBT-i Coach (US VA)	Not FDA-cleared	Anyone; designed to support therapy with a clinician9	Free on the App Store9
Calm, Sleep Cycle, RISE and most others	Not FDA-cleared; general wellness apps	General use	Free download plus subscription

Cleared does not mean better for everyone. It means FDA reviewed the program for a specific use (treating chronic insomnia). It says nothing about trackers, sound apps or meditation apps, which are not reviewed at all.

Picks by use

We pick one app per problem, against five fixed criteria. They apply to every app, whether or not it pays us:

1. The use it's picked for has at least C-grade evidence (see the evidence map below), or the page says plainly that it doesn't.
2. Where FDA clears programs for that use, we name the cleared ones and how to get them.
3. We checked the current price and platforms on November 2, 2026.
4. The app does one job well. We dropped several 2023 picks that overlapped (see "What changed").
5. Commission plays no part.

Chronic insomnia: a CBT-I program

Grade A. CBT-I is the first-line treatment for chronic insomnia in adults in the American College of Physicians guideline (strong recommendation)¹. Digital versions work: in the 2020 meta-analysis, insomnia severity fell by 5.0 points more than with control conditions after treatment, 4.0 points at up to six months and 3.5 points at one year². Face-to-face CBT-I did a little better, by about 3 points². In the largest single trial (1,711 adults), digital CBT also improved functional health, wellbeing and sleep-related quality of life over 24 weeks, compared with sleep hygiene education³.

If you can see a clinician: ask about SleepioRx or Somryst, the two FDA-cleared prescription programs^{4, 6}. Neither lists a consumer price on the pages we checked; cost depends on your insurer or employer.

If you want to start on your own: the VA's CBT-i Coach is free. The VA describes it as a companion to CBT-I that is "intended to augment face-to-face care with a healthcare professional"⁹, so it works best alongside therapy, not instead of it. Evidence for using it alone is thin: a 33-person pilot trial in veterans found insomnia scores fell from about 18 to 11 over six weeks, but it had no no-app control group⁸.

See a clinician first if you snore loudly, stop breathing or gasp at night, fall asleep while driving, or have low mood. Those can be signs of a different sleep disorder, which an app can't diagnose¹⁴.

A racing mind at bedtime: Calm

Grade C. Calm is a meditation app with sleep stories, soundscapes, sleep music and breathing exercises¹¹. In an 8-week trial of 263 adults with sleep disturbance, people asked to meditate with Calm for 10 minutes a day had less daytime fatigue, less daytime sleepiness and less pre-sleep arousal than a wait-list group¹⁰. The abstract does not report a between-group difference in sleep quality, and a wait-list control can't rule out expectation effects. So it's a reasonable wind-down tool, not an insomnia treatment.

Calm's in-app purchases on the US App Store were listed from $14.99 to $79.99 on November 2, 2026; the listing doesn't say which is monthly or annual¹¹. Headspace is a similar alternative; we found no comparable sleep trial for it in our searches.

Sleep schedule and sleep debt: RISE

Grade D for the app itself, built on sound lab science. RISE estimates your personal sleep need from up to 365 nights of data, then tracks a "sleep debt" over the last 14 nights, weighting recent nights more¹⁷. It also predicts daily energy peaks and dips from your circadian rhythm and suggests a bedtime and wake time¹⁶. The idea that sleep loss adds up is well supported: in a lab study, two weeks at 6 hours a night produced growing deficits in attention, while people's own sense of sleepiness levelled off¹⁸. We found no published trial showing that RISE's own estimates or advice improve sleep or performance. It costs $69.99 a year with a 7-day free trial, on iPhone and Android¹⁶.

Tracking with just a phone: Sleep Cycle

Grade C for detecting sleep in good sleepers, D for sleep stages. Sleep Cycle tracks sleep with sound analysis or the phone's motion sensor, flags snoring and sleep talking, and has a smart alarm that aims to wake you in light sleep¹⁵. A review of 11 validation studies found phone apps can detect sleep about as well as wrist actigraphy in healthy sleepers, but are poor at spotting wake time and at sleep stages, and Sleep Cycle performed poorly in clinical groups¹³. Treat its graphs as a rough diary, not a measurement.

It's a free download; Premium in-app purchases were listed from $2.99 to $57.99 on November 2, 2026¹⁵. Its App Store privacy label lists health, location, contact info and identifiers as data linked to you, and identifiers as used for tracking¹⁵. Recording audio in the bedroom also captures anyone else there.

Already wear a tracker: use its own app

If you already wear an Oura ring, a WHOOP strap, an Apple Watch or a Garmin, its own app will log sleep more consistently than adding a phone app on top. The same accuracy caveats apply. We compare them in best smart rings, WHOOP vs Oura vs Garmin and best recovery wearables. RISE can read data from these devices if you want its sleep-debt view¹⁶.

See the Oura Ring 5 · See WHOOP

Sleep sounds: no pick

A systematic review of 38 studies rated the evidence that continuous or white noise improves sleep as very low certainty, and called for better studies before it is promoted as a sleep aid¹². If a fan or rain sound helps you, Calm and RISE both include sounds, and many phones have a free built-in option. We don't recommend paying for a separate noise app. Our binaural beats guide covers that related idea.

Evidence map: graded by outcome

Grades: A consistent randomized trials or meta-analyses. B supported by randomized trials that are small or varied. C few or mixed trials, or trials showing no effect. D lab, animal or anecdotal only, or no trials of the app itself. X a safety signal or a way it can backfire.

Outcome	Grade	Best evidence	Notes
Digital CBT-I for chronic insomnia	A	33 RCTs, 9,364 people: Insomnia Severity Index −5.0 points after treatment, −3.5 at one year2. 1,711-person RCT: better functional health and wellbeing at 24 weeks3.	Most trials used structured programs (several weeks of sessions), not a sleep tracker
Digital vs face-to-face CBT-I	B	Face-to-face was about 3 points better on the ISI, within the authors' non-inferiority margin2.	A therapist is better if you can get one
CBT-i Coach used on its own	C	Pilot RCT of 33 veterans; scores improved but there was no no-app control8.	Designed to support a clinician9
Meditation app (Calm) for sleep-related symptoms	C	One RCT, 263 adults: less fatigue, daytime sleepiness and pre-sleep arousal vs wait-list10.	No between-group sleep-quality result reported in the abstract
White or continuous noise for better sleep	D	Systematic review of 38 studies: very low certainty12.	Can still mask disruptive noise; evidence is weak
Phone app measuring sleep and wake	C	Similar to actigraphy for sleep in healthy users; poor at wake time; worse in clinical groups13.	Not a substitute for a sleep study
Phone app measuring sleep stages	D	Accelerometer apps correlated poorly with polysomnography stages13.	Ignore "deep sleep" percentages from a phone
Sleep-debt apps improving energy or performance	D	No trials of the apps found. The underlying lab science on cumulative sleep loss is strong18.	Useful as a prompt to keep a regular schedule
Trackers making sleep worse	X	Case series: some patients became anxious about their data or spent longer in bed to raise their scores ("orthosomnia")14.	Stop tracking if it makes you anxious

How to choose a sleep app

• Start with the problem. Trouble falling or staying asleep most nights for months is the problem CBT-I was built for. Feeling tired despite enough time in bed is a reason to see a clinician, not to download a tracker.
• One app is enough. A CBT-I program already includes a sleep diary and wind-down techniques. Stacking a tracker, a sound app and a meditation app adds screen time at bedtime.
• Check what it measures. Phone apps infer sleep from sound or movement. They can't tell lying awake quietly from sleeping very well^{13, 14}.
• Read the privacy label. Sleep audio and health data are sensitive. Check the App Store privacy section before granting microphone access¹⁵.
• Count the yearly cost. Several apps renew automatically after a short free trial. Set a reminder before it ends.

Safety: who should see a clinician first

• Loud snoring, pauses in breathing, gasping, or morning headaches: these can mean sleep apnoea, which needs a proper sleep study. Phone apps can't diagnose it¹⁴.
• Insomnia alongside depression, anxiety or another health condition: talk to a clinician before starting a self-guided program.
• Severe daytime sleepiness, especially if you drive for work: get it assessed rather than tracked.
• If tracking makes you more anxious about sleep, stop. That pattern has a name in the sleep literature¹⁴.

Myths

• "My app says I got 40 minutes of deep sleep." Phone apps are poor at sleep stages¹³. Treat stage numbers as noise.
• "FDA-registered" or "clinically proven" on an app store page. Only two insomnia programs on this page are FDA-cleared^{4, 6}. Look for the K number.
• "You can't feel sleep debt, so you don't have it." In the lab, people's sleepiness ratings levelled off while their performance kept getting worse¹⁸.
• "White noise is proven to improve sleep." The certainty is very low¹².

FAQ

What is the best app for insomnia?

A CBT-I program. The FDA-cleared options (SleepioRx, Somryst) need a prescription^{4, 5, 6}. CBT-i Coach is a free starting point⁹.

Do sleep tracking apps work?

They give a rough picture of when you slept in healthy sleepers. They are much less reliable for wake time, for sleep stages and for people with insomnia¹³.

Is Calm or Headspace better for sleep?

Calm has a randomized trial in adults with sleep disturbance¹⁰. We didn't find a comparable trial for Headspace. Pick the one whose voice and content you'll actually use.

Is RISE worth $69.99 a year?

If a sleep-debt number gets you to keep a regular schedule, it may be. It isn't an insomnia treatment and its estimates aren't independently validated. See our RISE review.

Can a sleep app diagnose sleep apnoea?

No. Some apps flag snoring, but snoring alone doesn't confirm or rule out apnoea. Ask a clinician about a sleep study¹⁴.

Do I need a wearable?

No. For insomnia, a written or in-app sleep diary is what CBT-I uses. A wearable adds data, not treatment.

What changed in this update

The 2023 version of this page listed seven apps, including Noisli, Pzizz and Endel. We dropped the three sound and music apps because the evidence for noise as a sleep aid is very low certainty¹² and they overlapped with Calm and RISE. We added CBT-I programs, FDA status and evidence grades, and removed testing claims we couldn't document.
