Description

Did you know that our nervous system provides insight into our mental fitness and emotional health?

Heart rate variability (HRV) is a key measure of the health of our nervous system and how it responds to daily stressors and emotions in our environment.

Research has demonstrated that consistent meditation can help increase HRV.

Zendō assists you with your training to improve your mental fitness by providing real-time biofeedback and meditation techniques.

Track how your meditation experience is altering your physiology and improving your mental fitness over time.

Zendō requires permission to Apple Health app to measure your HRV and other health indicators during meditation.

The app creates a Mind & Body workout for each meditation session, working in concert with Apple Activity app and other developer apps that work with HealthKit.

HRV recording requires Apple Watch.

What’s New

Version 7.5

Now with no tracking. We removed the Facebook + Google SDKs. Reducing the download size of the app and the size of its karma. We added a new community experience to the Discovery tab too.

Frustrated

This is an app I would love to love, but . . . The instructions seem sketchy at best. Zendō’s support hasn’t gotten back to explain several issues. If the watch app is supposed to record HRV through the day per the onscreen instructions, it’s not working. I don’t understand HRV expressed as X(ms) and Support doesn’t either. When I meditate the iPhone app doesn’t show HRV over the length of the meditation (20+ minutes). It shows heart rate, and movement though. If this is an app to record HRV, it seems it should track that instead of a single number for the entire meditation with the abbreviation “ms” after it (with no interpretation).

The quest goes on for an app that works and that is explained probably.

Sorry that you are having a poor experience.

We’ll go back to the support team to see where we dropped the ball answering your questions.

Based on what you have written here, let me clarify a few things.

1: Apple Watch records HRV through the day, Zendō only records HRV when you explicitly start a session.

2: HRV is a computed property from heart rate. As your heart rate varies, the HRV increases. It is the variation in the heart rate that matters. When engaging in mindful breathing, you will see the heart rate graph develop a nice sine wave in sync with your inhale + exhale with an associated rise in HRV.

3: For this reason, the charts in the current version focus on displaying things that feed into the HRV calculation (heart/breath + movement) for each meditation. These are available in the Activity tab.

4: Once you complete your meditation session, we report back the SDNN in milliseconds and then add that to the Health app.

5: With this data in the Health app, Zendō provides a number of charts over the HRV dataset that can show you how you are progressing over time. If you only have one datapoint for HRV for a given time period in those chart, that is because you aren’t wearing your watch enough or correctly for it to take HRV readings when not using Zendō.

Hope that helps. We appreciate the feedback and will see what we can do to make how we display information more intuitive and our support process better.

It used to be good

I was appalled by this app forcing you to give it full access to write on your Heath app. If you don’t, the app crashes on your watch and fails to work. This change occurred after an update. It’s been months without a fix. I finally deleted it.

Developer Response ,

we are sorry. we were trying to ask for a new permission in that release -- and messed it up some people.

we just touched up those lines of code.

maybe try again?

be well.

Simple

Your app is uncomplicated and straight forward. It focuses on HRV and gives simple guidance to to measure, record, and improve. I’m experimenting with it to see if I can see a difference in my HRV when I listen different entrainment recordings while meditation to your app. It would be nice if there were a way to add comments to a particular recorded activity. Loved the breathing guidance.

Thanks for using the app and the feedback!
