Reduce your stress using 100% natural biofeedback technique based on heart rate detection with your iPhone’s camera. A single training session will immediately lower your stress and help you sleep better. Regular use helps normalizing blood pressure, improves immune system and health in general.

Stress Doctor visualizes respiratory sinus arrhythmia (RSA) which, in layman’s terms, is the rising and falling of your heart rate when you breathe in and out. When you inhale, pressure in your chest drops and consequently your blood pressure drops as well. Your autonomous nervous system (ANS) instantly increases your heart rate to compensate for this. A couple seconds later, the other systems for blood pressure regulation kick in and your heart rate starts to fall back to your baseline.

Stress Doctor helps you synchronize your breathing with your ANS to achieve more balance and less stress.

Using one of the oldest techniques of deep breathing, you can now take a moment out of your day to decompress and be conscious of breath. Your outlook on the day will change, you can tackle more projects, you can stop yourself from letting your mood effect your interactions with others, or help yourself wind down to sleep.

This technique has proven beneficial effects on:

  • lowering stress
  • helping you sleep better
  • reducing asthma attacks
  • reducing anxiety
  • lowering blood pressure
  • strengthen your immune system

It takes some practice to master the technique. Invest 5-10 minutes daily and collect at least 200 balance points with Stress Doctor every week. Share your experience with family and friends.

Stress Doctor FAQ

How do I use Stress Doctor?

When will Stress Doctor be available for Android platforms?

It’s on our list of things to tackle in the coming months–and *hint hint* maybe even with a significant facelift. Stay tuned!

    This is not as easy as you make it out to be, or maybe I have not done it enough times.

    • Azumio

      It’s not easy, just rewarding! Keep at it and you will see progress and feel better.

  • Jeff

    Why can’t I find this in the AppStore? And the direct link from this page doesn’t work either. How can I download this?

  • Nik

    I also can’t find it in the AppStore. I’m very disappointed.

  • jerome

    I ve been waiting for month for you guys to launch that app for Android! Where are you about this???

    • Azumio

      We do not have immediate plans to launch Stress Doctor on Android at this time. That said, I wouldn’t rule out a new and improved version for both platforms down the road!

  • Nicky

    could you show a picture on how the graph is supposed to look when you are doing this right? I don’t get it. Do I breath in when the graph next to the orange square (my finger as seen by the camera presumably) goes down? And if so, what does the big graph mean? Does the big graph show real time results or is there a delay? More info please….

    • Azumio

      See the video above. The big graph is showing your average heart rate over a period of time (see the numbers on the left hand side). You want this graph to look like a sine wave, a smooth up and down pattern. When you do this correctly you will see a yin-yang symbol appear beneath the wave. Instead of focusing on the graph, try focusing on your breath: inhale and exhale deeply, to the count of five each. Soon the graph will begin to line up with your breath!

  • Steve T.

    Don’t want a new and improved application. I’ll just take the existing app on Android now, please.

  • OnBartending

    *raising hand* Question – the two hearts on the left side are blood pressure read outs? Systolic and Diastolic? I forget. My questions is how does this aid in achieving the overall goal? Also how can we use it in real-time to adjust our breathing? What information can we derive? Many thanks. I am enjoying the app!

    • Azumio

      That is showing what your minimum and maximum heart rate was over the period shown on the screen. The app does not read blood pressure.

    Thanks for making HRV-f available on the iPhone. It works well except that the algorithm for awarding points is much more stringent than the emWave or StressErsaser, so that users are easily discouraged. For example I monitored a patient simultaneously with Stress Doctor + emWave for 10 minutes. While scoring 90% High Coherence on the emWave she only earned 13 balance points on the Stress Doctor. (At roughly 6 breaths per minute for 10 minutes only 13/60 or 22% of her breaths were “on target”.) Similar results were obtained when compared with the StressEraser. I have temporarily stopped recommending the Stress Doctor because individuals who do well with the other devices in my office get discouraged and stop trying because of the scoring issue. A well adjusted target threshold is essential for success with biofeedback of any type. I look forward to a “tweaked” Stress Doctor.
