Biofeedback is the future and the future is now - for everyone. No additional body sensors are needed anymore! Just take your iPhone and start VaYou.

VaYou Breath is innovative sound biofeedback. The app connects you directly with yourself by transforming your abdominal breathing into dynamically generated sounds.

It is very simple! You breathe relaxed and VaYou generates sounds from it - directly shaped by your breathing. With the help of real-time biofeedback, your breath, mind and heart increasingly flow as one.

VaYou Breath integrates with Apple Health by updating your values for resting heart rate, respiratory rate, and mindful minutes.

Key VaYou benefits

• Biometric Integration - VaYou provides advanced real-time breath and pulse detection without the need for additional wearables or expensive medical sensors.
• We have gone to the technical limits. VaYou converts the iOS motion/acceleration sensor data stream into high quality biosignals for breath and pulse (pulse only in lying position).
• In order to support the relaxation process, the VaYou algorithms learn from your biosignals and derived parameters how to best design the sounds so that they are most effective for you at that moment.
• No online connection needed while using - activate airplane mode for an undisturbed and healthy experience!

No other app or desktop software provides biofeedback like VaYou Breath.

Just listening to the breath-generated sounds leads you into a very personal flow experience. Your consciousness is more and more "absorbed" by the process, your thoughts come to rest. The mental state can be described as relaxed and calming breath mindfulness. It is almost automatic to "stay with the breath", easily and effortless.

Unlike with apps where you have to understand and follow spoken instructions, with VaYou Breath you can "switch off" right from the start. The resulting flow experience brings body and mind into harmony and this has a regenerating effect.

The regular use of VaYou Breath can have a generally positive effect on body and mind. Some of the reported effects are
• Calming the flow of thoughts
• Reduction of stress levels
• Self regulation of the heart and breathing activity
• Increase of creativity
• Improvement of mood
• Improvement of sleep.


Put on good headphones and choose one of the perfected Sound~Flows. Then select the duration, press START and place the iPhone on your lower abdomen, just below the navel. (It's usually better to loosen a belt if you wear one and slide the iPhone halfway into the belt line of your trousers or skirt.) Keep breathing and listening!

LIVE 1 and LIVE 2 is the app's main biofeedback mode. To be even more flexible, there is also a PACING mode, in which an adjustable breathing rhythm is played, which you simply breathe along. Without the need to look at the screen.

It is actually very easy to get into your personal "Flow~Breathing" and to experience and enjoy the balancing positive effect.


▪ The VaYou biofeedback algorithm that turns your breathing movements into amazing Sound~Flows
▪ The "Flow Journey" Sound~Flow, which guides you through a universe of different breath~sound experiences up to 30 minutes duration
▪ The "Four Fully" Sound~Flow for very effective and recreational short breaks
▪ All other Sound~Flows can be downloaded as in-app purchases within the app. And of course you get them for your LIFETIME, even if you change or loose your device.


• No subscription, no automatic renewal
• No hidden costs or unnecessarily large packages
• You only pay what you really like and want.

What’s New

Version VaYou 2.18.0

VaYou 2.18.0 is here with bug fixes and improvements.

It may be a good time to point out the following:
Breathing with VaYou activates the parasympathetic nervous system, which among other things controls all regenerative processes. It is also known as the “inner care system”.
You can “trigger” this yourself again and again by breathing with VaYou.
And if you activate your inner care system again and again, you also promote your ability to feel and act empathically.

Enjoy life in health ~ enjoy being flow ~
it's possible !

We want to really thank You for using VaYou ~ the #1 breath biofeedback app on the App Store.

Worth every penny

I never review apps but this one is too good not to. Helps me relax in a short amount of time. The sessions are addictive so I actually look forward to meditating and always feel better afterwards. I’ve tried several meditation apps and some are better than others. This is my favorite so far. There are a couple of sessions that come with the purchase price and a few others you can buy in the app if you want them.

Developer Response ,

Dear user FoxxyOx,
thank you so much for your positive feedback! We love it!
Regarding "addictive" - we haven't heard of anyone who has actually overdone it. Furthermore, VaYou~Biofeedback has no unwanted side effects at all ;-)
We wish you many more pleasant and profound VaYou times!

Incredible! I love it!

This app is incredible! I have autism and I’m trying to go off my Prozac so I wanted to download an app to help me start meditating. Today I was so anxious that I was nauseous and shaky. The first session was so nice I did a second one and after I felt not only calm, but happy and was smiling even. I’m going to start using this app at least once everyday!

Developer Response ,

Dear VaYou~user, thank you for your affirmative review! We would love to hear about your further experiences at! We already have evidence that regular daily use of VaYou Biofeedback can have an effect similar to a mild psychotropic drug. In any case we wish you many more enriching and deepening VaYou experiences! Lukas

Fantastic app!

By far the best relaxation app that I have tried...and I've tried quite a few. This app is intuitively easy to use, and the meditation programs it offers get me "in the zone" every time. Don't take my word for it. Try it for yourself!

Developer Response ,

Thank you for your positive feedback!
