How to Choose an Insomnia App (2026)

Quick answer: The best insomnia apps of 2026 are behavioral programs built on CBT-I, the first-line treatment for chronic insomnia. Six apps are built on that protocol: SleepioRx, Somryst, Rest, Sleep Reset, Stellar Sleep, and CBT-i Coach. Answer the questions below to discover which is the best fit for you.

Full disclosure: we build Rest, one of the apps in this tool. We've tried to be straight about where it wins and where it doesn't.

The American College of Physicians recommends CBT-I (Cognitive Behavioral Therapy for Insomnia) as the first treatment for chronic insomnia, ahead of medication, in its 2016 clinical guideline. The American Academy of Sleep Medicine says the same [1]. CBT-I works on the habits that keep insomnia going after the original trigger has passed: staying too long in bed, naps, a bed your brain has learned to lie awake in.

The first test of any real insomnia app is whether it runs on those principles or if it just helps you wind down with meditation and sleep sounds. Calm, Headspace and BetterSleep are in the second group. The six that pass the test are ranked, with a table and a profile each, in our article the best CBT-I apps.

What Each Question Means

1. What Do Your Insomnia Nights Look Like?

Insomnia shows up in three ways: trouble falling asleep, waking during the night and not getting back to sleep, and waking up too early, and many people have a mix of all of those. CBT-I works on all of them with the same core tools (a sleep window, a fixed wake time, rules for the time you spend awake in bed), so your pattern doesn't rule any program out. It does say when you'll need the help most: at bedtime, in the middle of the night, or in the morning when the schedule is set.

2. How Long Have Your Sleep Issues Been Going On?

Three months is the clinical line for insomnia [2]. Under it, short bouts can settle on their own, which means a full program may not be needed. Past it, the pattern itself is what keeps the problem going, which is the layer CBT-I was built to change [3].

3. Have You Tried a Sleep Program or CBT-I Before?

A first program and a second one are different situations. If you've never tried one, you don't yet know how you respond to a sleep window or to getting out of bed at 3am. If you started one and stopped, the question is what made you stop, usually the weeks when sleep gets worse before it gets better, or being left alone between sessions.

4. Do You Have a Prescription or Coverage for a Sleep Program?

Two of the apps, SleepioRx and Somryst, are prescription digital therapeutics cleared by the U.S. Food and Drug Administration (FDA). You can't download them from the app store: a doctor prescribes them, or an employer or health plan offers Sleepio with no prescription involved, and either route can make them free. Without a prescriber or coverage they aren't an option.

5. iPhone or Android: Which Insomnia Apps Run on Your Phone?

Not every program runs on both platforms. Rest is iPhone-only, with an Android waitlist; while the other programs run on both platforms. Your phone also decides whether the sleep log can fill itself from a watch: on iPhone, Apple Watch and anything synced to Apple Health can feed it. Programs still ask you to confirm the log each morning, because trackers count sleep well and time awake poorly [4], and time awake is what the schedule decisions depend on.

6. Who Should Run Your Insomnia Program?

Every program here teaches the same CBT-I components; who delivers them is the real difference. A human coach reads your diary and replies on a schedule. An AI coach can be there at any hour, by text or voice, and reads the log every morning. A self-guided course gives you the lessons and the schedule and leaves the doing to you. Some people don't want a program at all, only help settling down at night, which is what wind-down apps are for.

7. When Do You Want to Be Able to Access the Help?

Programs differ in when the help arrives. Weekly sessions, or a coach who replies every few days, suit people who want a plan and then room to run it. Help at 3am means someone, or something, to talk to while you're deciding whether to stay in bed, which only an always-on coach can offer.

8. How Much Are You Willing to Spend per Month?

U.S. prices, as of October 2026. The field runs from free (the U.S. Department of Veterans Affairs (VA) apps, Rest's free tier, and Sleepio when a plan covers it) to around $50 a month for a coached app, around $200 for a self-paced course, $297 per 28 days for a human coach, and about $400 cash-pay for a prescription program. Health savings and flexible spending accounts (HSA/FSA) cover some of them. Each profile below gives the exact price.

What Each Insomnia App Result Means

Sleepio (SleepioRx)

Big Health's program has the deepest evidence of any insomnia app: a placebo-controlled trial, then trials with 1,711 and 3,755 participants [5]. The UK's National Institute for Health and Care Excellence (NICE) recommends it in primary care, and the FDA cleared it as SleepioRx in 2024 [5]. It runs as six weekly automated sessions, tailored from a sleep test and the diary you keep in between, with reminders, relaxation audio, an article library and the option to pause. Access is by download code from a provider or sponsor; cash-pay is around $400.

Somryst

The first insomnia app the FDA cleared, in 2020. It's built on SHUTi, a web program whose randomized trial of 303 adults took time to fall asleep from about 44 to 24 minutes over nine weeks [6]. Somryst is that nine-week automated course for adults 22 and older, prescription only. There is no coach to talk to, and coverage is inconsistent.

Rest

Rest is the first fully AI-led program built on the principles of CBT-I. It runs as a daily conversation, by text or voice, with a coach available around the clock. Each morning the coach reads your sleep log, adjusts your sleep window as your sleep efficiency improves, and works with you on the hard nights and the daytime habits; tell it you're traveling or ill and it suspends the rules that don't apply until you're back. It is available in both English and Spanish, iPhone only, $29.99 for the first month and then $49.99 a month [7].

In Rest's 2026 real-world outcomes study, the 318 users who completed eight weeks went from 75% to 88% sleep efficiency and cut time to fall asleep by 52% and time awake at night by 49%; that is a company whitepaper covering the people who finished, with no control group, not a trial. Rest is not a clinical treatment or a substitute for medical care.

Rest, Free Tier

The same app without the coach. Free: the personalized sleep-restriction schedule and the algorithm behind it, the full education program, the nightly sleep log with Apple Watch fill-in, sleep metrics and trends, relaxation audio, and a private link to share your data with your clinician [7]. The AI coach and the daily check-ins are the paid part.

Sleep Reset

An app on CBT-I principles plus a named human coach who messages you inside the app on weekday business hours and updates the plan every few days. Its completer study of 564 people over 12 weeks reported sleep efficiency rising from 82% to 89% [8]. $19 for the first week, then $297 per 28 days, HSA/FSA eligible; iPhone and Android.

Stellar Sleep

A self-guided daily course of five to ten minutes through stimulus control, sleep restriction, cognitive restructuring and relaxation [9]. A web quiz routes you to the app or to an insurance-billed clinician; the app needs an access code. Price is listed at $188 a month, varying by program. HSA/FSA eligible. Its effectiveness figures are the company's own. iPhone and Android.

CBT-i Coach and Insomnia Coach

Two free apps from the VA, built with the Department of Defense and Stanford, for anyone, veteran or not [10]. CBT-i Coach is a diary and toolkit designed to sit alongside CBT-I you're doing with a provider; Insomnia Coach is a five-week self-guided plan for people without one. Nothing adapts day to day. iPhone and Android, English only.

Calm, Headspace or BetterSleep, Alongside a Program

They are mainly wind-down libraries. Calm's eight-week randomized trial in adults with sleep disturbance found less pre-sleep arousal than a wait-list control [11]. Headspace's 2025 trial in people with clinical insomnia found remission around 12 to 14%, well below what digital CBT-I trials report, and its authors say the program was not designed as CBT-I [12]. BetterSleep's only effectiveness figure is a company survey [13]. None of the three runs a sleep window or stimulus control. Prices vary from $12.99 to $14.99 a month, or $59.99 to $69.99 a year [13].

The wider field is in the best sleep apps.

Before You Start Any Insomnia Program

Sleep restriction makes the first weeks harder. It shortens your time in bed to rebuild sleep drive, and in a four-week study of 16 patients, objective sleep fell by 91 minutes on the first night and daytime sleepiness stayed elevated through week three [14].

Don't drive or do safety-critical work while you're that sleepy. A program that gives you a sleep window should say so, and should move the window as your sleep and your daytime functioning change instead of handing everyone the same schedule.

Insomnia is also sometimes a symptom of something else. Loud snoring or gasping in sleep, an evening urge to move your legs, overwhelming daytime sleepiness, a major change in mood, or a sleep problem that is new or getting worse fast all call for a clinician before, or alongside, any program.

Frequently Asked Questions

Do insomnia apps actually work?
Digital CBT-I does. A 2016 meta-analysis of randomized trials of internet-delivered CBT-I found faster sleep onset, less time awake at night and lower insomnia severity across studies [15]. The result depends on the app running CBT-I and on you finishing the program. Meditation and sound apps help with winding down and don't deliver the behavioral core.

Is there a free insomnia app?
Yes. Rest's free tier on iPhone includes the personalized sleep-restriction schedule and the education program; the AI coach is paid. Sleepio can be free when an employer or health plan covers it. CBT-i Coach and Insomnia Coach, from the U.S. Department of Veterans Affairs, are free to anyone on iPhone and Android.

Is Calm good for insomnia?
Calm lowers pre-sleep arousal and makes bedtime easier, and a randomized trial supports that. It has no sleep window, no stimulus control and nothing that adapts to your sleep log, so if insomnia has lasted months, use it alongside a behavioral program.

Which Insomnia App Should You Start With?

If you've cycled through sleep stories and sleep scores and your insomnia hasn't changed, the tools were built for a different problem. If a daily conversation with a coach you can text or talk to, on the principles of CBT-I, is the form you'd stick with, that's what Rest is built for.
