Best 4-7-8 Breathing Apps for Sleep

4-7-8 breathing is easy to describe and annoying to do. In through the nose for four, hold for seven, out through the mouth for eight. The description takes ten seconds. Doing it in the dark, accurately, for ten minutes, without watching a clock, is the part an app is actually for.

Most breathing apps are built for the daytime version of this problem — an animated circle you watch on a bright screen during a break at work. At 1am, with your eyes shut and the phone face down, almost none of that matters. This is what does.

What to look for

It counts for you, out loud or by touch. If you have to look at the screen to know where you are in the cycle, the app has handed the timing back to you. A voice, or a vibration pattern on each phase, is the difference between doing the technique and watching a visualisation of it.

It works with the phone face down. The most comfortable way to run a breathing drill in bed is with the phone on your chest or beside you, screen off. That means haptics, and it means haptics you can turn down: a phone on your chest under a duvet transmits vibration completely differently from one held in your hand.

The screen does not stay lit. A bright display next to your face for ten minutes is working against the thing you opened the app to do. Ideally it dims as the session runs and goes dark when it finishes, by itself.

It does not sell to you at 3am. This is a real problem. Sleep apps have among the worst paywall reputations on the stores — across 240 competitor reviews we pulled in September 2026, price and paywall complaints were the single largest category, ahead of crashes and bugs. Being shown a subscription screen at three in the morning, when you opened the app because you could not sleep, is the reason.

It tells you the truth about the evidence. 4-7-8 is a slow-breathing technique. Slow breathing with a long exhale has a real physiological mechanism — an extended exhale raises vagal tone and lowers heart rate — and that mechanism is well studied. The specific 4:7:8 ratio is not: there is no good trial showing 4-7-8 beats other slow-breathing ratios for falling asleep. An app that says “clinically proven” about the ratio is telling you something nobody has established.

It is honest about free. “Free” that means three minutes and then a wall is not free. Look for an app that gives you the technique at a length that actually helps.

What does not matter

Streaks and badges. A sleep app that gamifies bedtime is giving you one more thing to perform at, at the exact moment the goal is to stop performing.

A sleep score in the morning. Nothing you can do about it, and for a lot of people a bad score becomes tomorrow night’s worry. Orthosomnia — anxiety caused by sleep tracking — is a documented thing.

A huge sound library. Fine if you want sounds. It is a different product from a breathing app, and libraries are where subscription pricing tends to live.

Where Sleep Switch fits

Sleep Switch is an Android app built for the eyes-closed case specifically. Its 4-7-8 drill counts every phase for you — with a voice, or with an adjustable haptic pulse so you can follow it with the phone face down — and the screen dims as it runs and turns itself off at the end.

It is free at every length up to fifteen minutes, and it will not show you an offer between 2am and 5am, at all, by design. Every technique carries a label in the app saying how well studied it is: 4-7-8 is marked “mechanism studied”, which is the accurate description — the long exhale is supported, the exact ratio is not.

If 4-7-8 turns out not to suit you, two others are in the same app: Soft Exhale, which is just a longer breath out than in without the counting, for nights when 4-7-8 feels like homework; and Even Breathing, resonance breathing at one steady slow pace. There are also six non-breathing techniques, including the cognitive shuffle for when the problem is a racing mind rather than a racing pulse.

A note on the ratio

Andrew Weil popularised 4-7-8 and the counts are not arbitrary: the exhale is twice the inhale, which is the part most likely to be doing the work. If the 7-second hold makes you uncomfortable — and it does for plenty of people, particularly with any respiratory condition — shortening everything while keeping the exhale longest (4-4-8, or even 3-3-6) keeps the mechanism and loses the strain. You are not failing the technique by doing that.

If breathing exercises consistently make you feel short of air or panicky, stop, and mention it to a doctor rather than pushing through.

And if breathing is not the problem

Slow breathing addresses arousal. If you are already calm and your head is simply generating content — replays, plans, an argument you did not have — breathing will not touch it, and cognitive shuffling is the better fit. If you have been awake for a long stretch already, the answer is neither: get out of bed.
