When you're stressed, your heart and breathing get out of sync. BreatheSync gets your breathing and heart back in sync fast, so that you feel more relaxed and think more clearly. (No external sensor required.)

BreatheSync is a simply designed iPhone app that helps you get in sync wherever you are. It picks up your pulse through your finger on the iPhone camera lens, analyses it and gets you breathing in sync with your heart. We call this synchronised biofeedback breathing. You'll call it 'a great way to feel great fast'.

After only 1-3 minutes you will feel more centred, more relaxed and more able to think clearly. BreatheSync directly affects your Autonomic Nervous System which helps reduce your stress levels.

It is also the world's first biofeedback breathing app that also gives you a well-being score, your WQ, so you can track your progress. Your WQ is based on your pulse rate variation, which is affected by your nervous system, and gives a good indication of your inner well-being.

People around the world use BreatheSync everyday -

1, To reduce stress

2, To relax

3, To get in the zone (to perform, to create or to produce)

4, To alleviate anxiety

5, To aid mindfulness and meditation

6, To prepare for sleep

7, To lower blood pressure*

8, To increase self-control

9, To improve their immune system

10, To measure and track their inner well-being

11, To feel good fast

Get in sync now. Follow your heart.

Ratings and Reviews

Cool, when it works


Detects finger less than 1% of the time. How can you possible trust the read results based on that.

Barely works


Doesnt work more than it does. starts and stops a lot, regardless of finger position or pressure.....UPDATE Does not work whatsoever now

Love It


I love that it is simple to use and I can do it very quickly at work for a quick break to help me calm down and relax. Quick is the key word! Maybe I can eventually work my way up to longer breathing breaks. I have an extremely stressful job and this is something doable to help me lower my stress. The reminders are great. I also like that it responds to my heart rate and adjusts the breathing rate to what is right for my body instead of imposing a generic breathing rate that might not be right for me. I like the look, feel and sounds. They are simple, calm and relaxing. I like that there is a simple visual cue and calming aural cue. I would love more data to possibly identify stressful times of the day, week, month etc. so that I might be able to put more preventative measures in place during these times. I'm looking forward to a version for Apple Watch.
