📝 About this app
Already breathed today?
Probably! We are always breathing, but mostly unconsciously. What a pity!
Because we can achieve so many positive things for ourselves through breathing:
When you breathe at your optimal breathing rate, your heartbeat synchronizes with your breathing and beneficial, balancing and healing processes are set in motion that bring both your psyche and your body into optimal balance.
BreathTuner is the first and only app that allows you to find your personal and optimal breathing frequency. It is also called resonance frequency and is determined by analyzing breathing and heart rate variability (HRV) simultaneously.
Take the basic test and you'll know how to set your Apple Watch for Breathe (Meditation) to get the most benefit for you! Or do you use one of the many Breath-Pacers or do daily exercises to improve heart rate variability? Even then, you should use BreathTuner to find out at what breathing rate your HRV is optimal. No other app can currently give you this fully automated functionality. Did we mention that the basic functionality costs next to nothing?
BreathTuner uses scientifically proven algorithms, is based on the latest research and uses high quality and proven HRV technology from our HeartBreath app. BreathTuner guides you through a series of simple exercises while being paced by the soothing breath sounds of the VaYou Biofeedback app. The BreathTuner measurement is at once a relaxing and even meditative exercise that enjoyably centers your mind on the flow of your breath. In doing so, the app measures your abdominal breathing and heart activity, and it does it all using only your iPhone! For this, we went to the technical limits.
You don't need an extra sensor, but you can use a chest strap like the Polar H10 as an alternative for pulse detection. This captures a real ECG and we analyze it for the HRV calculation. But BreathTuner works just as well with the finger pulse measured via the iPhone camera.
And if you want to become a BreathTuner Pro-User, even more detailed analysis is available via an In-App Purchase. You can then determine your individual breathing resonance frequency with very high accuracy!
BreathTuner was developed with the utmost care by the makers of the apps HeartBreath HRV and VaYou Breath Biofeedback. You get a quality product at the cutting edge of scientific research with the most beneficial breathing sounds available in the world today.
BreathTuner integrates with the Apple Health app (Mindful Minutes).
To breathe costs nothing, also air is fortunately still free and BreathTuner is at your disposal - almost free! Awaken your full potential - and use your individual and optimal breathing frequency - best right here, right now.
In this spirit - all the best on the way to you and don't forget to always take a deep breath - your BreathTuner
