The short answer
Best app for panic attacks
The best app for panic attacks is the one that opens straight into a guided breathing flow with no quiz, no profile, and no paywall. The breathing technique with the strongest recent evidence is cyclic sighing, and because its evidence comes from daily practice, the acute tool and the maintenance practice should be the same technique in the same app. Stillee is built that way, and the panic flow is free, forever.

What to look for
The criteria that actually matter.
A 2023 Stanford randomized controlled trial compared three controlled breathing techniques against mindfulness meditation across a month of daily practice. Cyclic sighing, which is two short inhales through the nose followed by an extended exhale through the mouth, outperformed the others on mood improvement and reduced respiratory rate. It is the breathing pattern with the strongest recent RCT evidence against an active mindfulness control. Across the clinical literature, controlled breathing and grounding are the two interventions with the most consistent acute effect on panic symptoms.
-
One tap from a visible button, no nested menus
Panic shrinks the window for decisions. The button has to be on the home screen, not behind a tab. If you have to look for it, you will not use it.
-
No paywall on the panic flow
A subscription gate in front of someone in acute distress is a design failure and an ethical one. The acute relief surface should be free, always, for whoever needs it.
-
Evidence-based breathing as the default
Cyclic sighing is the technique with the strongest current evidence for acute mood shift. Box breathing and 4-7-8 are reasonable alternates. A pattern with no clinical backing is a red flag.
-
Reality-anchor prompts for dissociation
A substantial minority of panic attacks include depersonalization or derealization, the feeling of being outside the body or the room. Standard breathing alone does not help with this. The app should include grounding prompts that ask you to name what you see, hear, and touch.
-
A direct line to crisis support
A real person on the other end of a phone is sometimes the right answer. The app should have a single-tap path to a crisis line in your region and, if you set it, to a trusted contact.
-
No quiz, no profile, no waiting
The first frame is the breathing. Personalization happens later. If the first thing the app asks you is your name, it was not built for this moment.
-
The daily practice lives in the same app
An attack is ten minutes; most of the work happens in the days between. Many people end up running two apps, one for the attack and one for the daily practice, and the practice is what gets dropped. Look for an app where the technique you reach for mid-attack is the one you can practice daily, so the two reinforce each other.
Where Stillee fits
What we built, against those criteria.
The panic button lives on the home screen
Tell Stillee about panic once, in onboarding, and the button is there — in the same place, every day after. Settings can turn it on or off at any time. You do not navigate. You tap it.
Cyclic sighing is the default pattern
The Stanford-tested technique opens the flow. Two short inhales through the nose, a long exhale through the mouth. The visual leads the rhythm; you do not have to count.
Three routes for three textures of panic
Racing, drifting, spiraling. You pick the one that matches what is happening. The flow adapts. There is no wrong answer.
Free, forever, no payment before you start
The panic flow opens without payment and without a profile setup. The part of the app that has to work when nothing else does was built that way on purpose.
One technique, both jobs
The Stanford evidence for cyclic sighing comes from five minutes of daily practice, not from emergencies. In Stillee the same pattern opens the panic flow and ships as a daily breathing Shape, so the breath you reach for mid-attack is the one you already know. The aftermath flow, the journal, and the programs carry the longer work.
FAQ
The questions people ask after they ask the first one.
What helps a panic attack in the moment?
The two interventions with the most consistent acute evidence are controlled breathing, specifically an extended exhale, and grounding through the senses. The Stanford 2023 trial found that cyclic sighing, which is two short inhales followed by a long exhale, produced a larger mood improvement than mindfulness meditation over the same period. If derealization is present, reality-anchor prompts (naming what you see, hear, and touch) help to reconnect with the body and the room.
Is it safe to use a meditation app during a panic attack?
A guided meditation that asks you to close your eyes and observe your thoughts can sometimes deepen panic, especially when dissociation is part of the experience. The right tool in the acute moment is a breathing flow or a grounding exercise, not a body scan. An app designed for panic should know the difference. Stillee opens the panic flow with breathing, not introspection.
What is cyclic sighing?
Cyclic sighing is a controlled breathing pattern. You inhale through the nose, take a second smaller inhale on top of the first to fill the lungs, then exhale slowly through the mouth. Five minutes a day for a month produced larger mood gains than mindfulness meditation in a 2023 Stanford randomized controlled trial led by Andrew Huberman and David Spiegel.
When should I call a crisis line instead of using an app?
If you are thinking about harming yourself, if you cannot keep yourself safe, or if the panic is not lifting after twenty or thirty minutes of focused breathing, please reach a person. In the US, call or text 988. Outside the US, findahelpline.com lists local services. An app is a companion, not a substitute for a human voice on the line.
How is the panic flow different from regular meditation?
The panic flow opens at the breathing screen with the rhythm already starting. There is no introduction, no choice of teacher, no setup. The interface dims to night colors. After the acute moment passes, the flow surfaces a short reflection and a way back to the rest of the app. It is one specific tool for one specific moment.
Do I need a separate app for daily practice between panic attacks?
No, and the split is worth avoiding. The evidence behind cyclic sighing comes from daily practice: five minutes a day for a month in the 2023 Stanford trial, which is what improved mood and lowered resting respiratory rate. In Stillee the same pattern opens the panic flow and ships as a daily breathing Shape, and the aftermath flow, journal, and multi-week programs carry the longer work. The technique you trust at the worst moment works better when it is the one you already practice.
Is the panic flow really free?
Yes, forever. The full library and the multi-week programs are included in the subscription. The acute relief surface is not.
