What the Skin Resonance app does now: a new player, headphones or speakers, and the October 2026 update

The app had two updates this month, and the second changes how it looks and plays. Here is what they add, and a tour of everything else inside, for anyone who has not opened it for a while or is deciding whether to.

Skin Resonance is a web app of sound-led routines for skin that is reacting to stress, poor sleep or a hormonal week: binaural beats and solfeggio tones generated live, arranged into timed steps, with room for the mask, serum or gua sha you already own. It costs €12 once, and every update since launch has arrived in the app people already have. October brought two updates. The second, in the second week of the month, changes how the app looks and how a routine plays. The first added slow breathing, dark mode and playing with the screen off. Both are below, newest first, followed by everything else that was already inside.

A new look, and a player that fills the screen

The app is calmer to look at. Four tabs along the bottom, Routines, Build, Saved and Log, replace the long single page, and each routine card shows when it is for, how many minutes it runs, and a strip of coloured bands, one for each step, so you can see the shape of a routine before you start it.

Press Start and the routine fills the screen in a warm, dark clay. A ring around the timer fills as the step runs, and a thinner ring outside it fills over the whole routine. Inside the ring sits the time remaining and a slow wave drawn from the sound itself, which drifts across at an unhurried pace rather than flickering at the beat. Under the ring are the steps as a row of bars, then back, pause and skip, then the instruction for the step you are on and any tool it calls for.

Back works the way it does on a music player: one tap restarts the step, and a second tap straight after goes to the step before. Tap any of the bars to jump to that step. Hide shrinks the player to a small bar so you can look at something else without stopping, and End asks before it ends a routine, so a stray tap in the dark does not cost you the session.

Headphones or speakers, your choice

There is now a Headphones or Speakers switch at the top of the Routines tab and on the player, and the app remembers which you chose. On Headphones, nothing has changed: the binaural steps play as two tones, one in each ear, and the beat between them is made inside the head.

On Speakers, the same steps play as a pulsed tone instead: a single tone, an octave higher, whose loudness rises and falls at the beat rate, so the rhythm survives being played out loud. This is an alternative, not the same thing. A pulsed tone is an ordinary sound that anyone in the room can hear, and the studies on binaural beats do not carry over to it automatically, so headphones remain the better choice when you have them. The solfeggio tones and the soundscapes sound the same either way. You can switch in the middle of a step, and the sound changes over with a short fade.

Sound mix, and the whole routine on one panel

Below the player, Sound mix sets the volume, and then the tones and the noise bed separately, so you can bring the frequencies forward or let the brown noise carry more of the session. The soundscape and the level are there too, so nothing needs changing before you press Start. A second panel, This routine, lists every step with its notes, the tip for the routine and the tools it uses, with Change beside them, and the buttons to save or print it.

Smaller changes

The level once called Sound and rest is now called Sound only, which says what it is: the routine with no skincare steps. Older entries in your log show the new name. The tool lists, where you tell the app what you own, now have a None option on every list, so you can say you have no active device or no mask and the routine adapts.

A routine now ends with two soft notes, falling gently, so you know it has finished without opening your eyes. They are left out where they would do harm: after Tired, dull skin, and after any routine that ends in deep delta or a sleep fade, the routine ends in silence so it does not wake you. If you would rather have silence every time, the menu has a switch, Chime when a routine ends.

The app also has a new icon: the player in miniature, a ring and a slow wave on the same clay. On some phones the icon on the home screen takes a while to change. There is no need to remove the app to hurry it, and on an iPhone removing it would also remove your log and saved routines.

If you prefer a lighter screen, the player now comes in cream as well as clay, in the colours of the Routines page; choose it under Player in the menu. And the log now fills itself. Every routine you play for a minute or more is recorded with the time it actually played, so pauses and skipped steps do not count, and the Log tab shows your last fourteen days as a bar chart. When a routine ends you can add a note on how it felt, as before.

Earlier in October: slow breathing, dark mode and the screen off

The first update added a slow-breathing routine at 5.5 breaths a minute: five and a half seconds in through the nose, five and a half out, the pace the heart-rate-variability research points to (Lin and colleagues found it produced the highest heart-rate variability of the rates they compared; Lehrer and Gevirtz set out why in their 2014 review). A circle grows for the in-breath and shrinks for the out-breath, with the words breathe in and breathe out inside it, and the first four breaths are shorter, so you are led down to the pace rather than dropped into it.

A voice guide welcomes you, counts you into the first breath, marks halfway and brings you out at the end; it can be switched off. Under the breathing sit the 7.83 Hz bed from the other routines, a low tone that rises and falls with each breath, and the stream soundscape, which swells a little on every in-breath so that you can close your eyes and follow it by ear. It runs five, ten or twenty minutes, and on Android a Vibrate switch gives a short buzz at each turn of the breath, so the phone can lie face down. The research behind the pace is on the slow breathing page.

The same update brought dark mode, which follows your phone's setting and can be pinned in the menu under Appearance; the player itself is always the warm clay. The five soundscapes were level-matched so they sit at the same loudness under the tones. And the app now keeps playing when you lock the phone, with the routine's name on the lock screen and buttons to pause, skip and go back, so headphone buttons work too. If a particular phone does not behave, a switch in the menu, Keep playing with the screen off, returns the app to how it was.

Everything the app already did

There are fourteen routines, one for each state your skin might be in: slow breathing, tired and dull skin, stress breakouts, puffiness, cellular rest, tension and tightness, hormonal balance, period week, perimenopause and menopause, ageing and elasticity, pre-event glow, post-treatment recovery, post-travel recovery and seasonal change. Each has two levels. Sound only uses the frequencies alone; With skincare builds the same routine around the tools you own and tells you when to use each one during the session. Slow breathing runs five to twenty minutes and the other routines thirty-five to seventy, in timed steps, and the last step fades gently so it can carry you into sleep.

The sound is generated in real time on your phone rather than streamed: binaural beats over a tuned brown-noise bed, solfeggio tones as the carrier frequencies, a low-pass filter and click-free fades, pauses and step changes.

The Build tab makes a routine from scratch: every sound in the app is listed with a line on what it does; pick the ones you want, set the minutes for each, drag them into order, and start it or save it by name. Routines you like can be saved by name and found again in the Saved tab. Every session is logged for you, with a note if you want one, and the Log tab builds into a history you can look back over. Everything you enter stays on your device. There is no account, no sign-in, no ads and no tracking, and after the first visit the app runs entirely offline.

Suggest a feature for the next update

The app keeps changing after you buy it, and the people who use it are the best guide to what it should do next. If there is a routine you would like added, a length that would suit your evenings better, a soundscape you miss, or something in the app that gets in your way, write to hello@skinresonance.com, use the contact page, or tap Contact & feedback in the app's menu. Every suggestion is read, and the ones that come up most often shape what is built next.

How the update reaches you

Skin Resonance is a web app, so there is nothing to install and no version to buy. Open it from your home screen or your private link and the new version is there, with a short note of what changed if you are coming from an older one. If your phone still shows the old app, open the menu and choose Check for updates. Your saved routines, your log and your settings carry over untouched. Everything in these updates, and everything that comes after them, is included in the €12 you paid or will pay once. If you do not have it yet, the free ten-minute routine plays in the same player, and the app itself is one page further on.
