Built by highly sensitive people, for highly sensitive people
Everything Sia can do for you
We know what it feels like when the world gets too loud, too fast, too much. That's why Sia opens on one question — how much room do you have? — and follows your answer.
Real support for real situations
This is what makes Sia different. Instead of generic advice, you get the way out of the exact situation you're in. Overwhelmed at a dinner party. Drained after a hard conversation. Overstimulated in a crowded space. We've been there, and we wrote something for each of those moments — 36 of them, in English and in German.
Now
The acute flow for the moment you're in, never more than two taps away. It says how many steps and how many minutes before you tap. No scrolling, no walls of text.
Before and after
Prepare for the next time, look back once it's over, and understand why this situation lands so hard on your nervous system. Because you process things deeply, and knowing the "why" genuinely helps.
Written by people who get it
Every situation is written natively in English and in German — never translated — by people who know high sensitivity from the inside and by experts who specialise in it. It's not clinical. It's not condescending. It feels like talking to someone who truly understands.
Example situations in the app
And more. Each one is written twice — in English and in German.
When you need relief right now
Your nervous system doesn't work on a schedule. The acute part of Sia is there whenever you need it, no appointment necessary, no account, free forever.
The sun
At the top of the home sits one light: the moment Sia thinks is closest to you right now — because you said where life is a lot, because it helped before, or because of the hour. Under it, two more.
Breathe with me
Always there, always free, never more than two taps away. When there is no room for anything else, one long breath with the screen is enough.
How much room?
Sia asks how much room you have. Barely any: only the breath. Some: short ways in. Plenty: the whole library. The light follows your answer.
A next time
After a moment that helped, Sia asks whether there is a next time. Name it — the meeting, the train, the family dinner — and the sun holds it until then. One quiet hello, only if you say yes.
Understand what helps you
You process things deeply. You want to know why something works, not just be told to try it. We respect that — this is the before and the after, and it's what Sia Plus is for.
Techniques that explain themselves
Every technique comes with clear steps and a simple explanation of why it works. No jargon. Just honest clarity about what it does for a highly sensitive nervous system.

My life · Me
Sensitive people need a place that feels safe. In Sia it's two: My life, where you see where life is a lot, and Me, where what you saved lives. Private, on your phone, no account.
My life
Six areas — body & senses, nights, calm, people, work, growth — that light up where you have been. Each opens on the moments that belong to it.
What helped
Sia remembers what helped. The moments you said worked come back first, so the way out is always where you left it.
A word after
After a moment, one gentle question: did it help? A tap is enough. Over time this is how Sia learns what works for you — no scores, no streaks.
What your weeks show
See when it gets much, in which area, and what helped then. Your own patterns, read from your phone alone. Part of Sia Plus.
Designed around you
Sensitivity isn't one-size-fits-all. Sia follows how much room you have today, where life is a lot, and what has helped before.
Smart Search
Find what you need instantly. Sia understands synonyms and related words, so searching for 'anxious' also finds results for 'nervous' or 'worried'.
A quiet arrival
Your first minute feels like a gentle conversation, not a setup screen. One question on the way in — where is life a lot? — and the home is already yours.
Home Screen Widgets
The breath and your named moment right on your phone's home screen. Support without even opening the app.
Your Look and Feel
The light dims when you have barely any room and opens when you have plenty. Larger text, less motion, a calm palette — small details that matter when you're sensitive to your surroundings.
Built on trust
When you feel deeply, trust matters. We built Sia the way we'd want an app to treat us.
Privacy First
What you answer, do and save stays on this phone. No selling, no surprises. Analytics only after you say yes, and never a word of what you wrote.
No account
Use the app without creating an account or sharing your email. Just open it and start.
Community Driven
Vote on upcoming features, suggest what's missing, and join the beta community to try things first. Sia grows with its people.
Works Offline
No internet? No problem. Every acute situation and the breath are on the phone and work without a connection.
