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.
Breathe Yourself Better with BreatheSync.

Great Concept, Need Improvement

The 2 Stars are for what this app intends to be. This app could help significantly improve well being for countless people—IF it worked! Please do what’s necessary to improve functionality of this app. It continues to freeze during the “Breathe In, Breathe Out” cycle. I’d rather download a Metronome app and use that because the disruption brought about in this app renders it useless for me. Please accept this as constructive criticism because if improved, this app could help so many people!

Same issue as “cool when it works”

When I first got this app, it worked well and consistently. Now it doesn’t work at all. So much potential and so disappointing. Hoping you can fix it...

Cool, when it works

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