## What is Optimal HRV?

Are you feeling stressed, burned out, or just not yourself? Optimal HRV is the guided biofeedback app that teaches your body to calm down — for real. Backed by a Harvard Medical School mindfulness expert and trusted by athletes worldwide.

Optimal HRV pairs real HRV data with live biofeedback, so every session trains your nervous system to handle stress better — not just tells you that you're stressed.

Why HRV and Biofeedback Training Work
Your Heart Rate Variability (HRV) is a window into how well your body handles stress, anxiety, and recovery — and biofeedback is how you train it to improve. Together, they show you what's happening inside your body, then guide you to change it in real time.

With Optimal HRV, you can:
• See how stressed — or relaxed — your body really is, using real HRV data.
• Learn what actually helps you recover, from sleep to workouts to busy workdays.
• Use live biofeedback to train your body to relax faster, right as it's happening.
• Discover your own personal "perfect breathing rhythm" through guided sessions.

Features You'll Actually Use
• Daily Check-Ins — take a quick reading each morning, or anytime you want to see how you're doing.
• Your Perfect Breathing Rhythm — a simple test finds the exact breathing pace that works best for you.
• Live Feedback While You Train — a simple on-screen guide shows you when you're doing it just right.
• Calming Mindfulness Sessions — guided practices created with a Harvard Medical School mindfulness expert, covering stress, anxiety, pain management, athletic performance, and more, with calming narrations in your choice of voice.
• Easy-to-Read Progress — see your trends over days, weeks, and months, no data expertise needed.
• Video Tutorials — learn HRV concepts and techniques at your own pace.
• Make It Yours — adjust sounds, pacing, and reminders so training fits your life.
• Available in 14 Languages — use Optimal HRV in your native language.
• Device Testing — quickly verify if your heart rate monitor works with the app.
• Great for Teams Too — employers and coaches can track group wellness together (Dashboard access needed).

Why Optimal HRV Works with External Sensors (Not Apple Watch)
We choose precision over convenience.
Apple Watch is great for daily wellness, but Optimal HRV is built for serious HRV training. That's why we connect directly to an HRV monitor via Bluetooth — they deliver millisecond-accurate R‑R intervals that wrist sensors can't match.

What that means for you:
• More accurate data – better insights, better decisions.
• Real-time streaming – no gaps, no guesswork.
• Reliable results – trusted by athletes and coaches worldwide.

### 2/5 — Doesn't work

*2026-08-12*

My device passes the compatibility test with flying colors, but hrv readings no longer work. Worked fine for months, and the heart rate monitor works with other apps. Trying to submit an issue with logs doesn't seem to do anything. I regret paying for this subscription.

### 1/5 — Wasted hours of my life trying to get to work

*2026-02-05*

A waste of time. I purchased the lifetime subscription but am unable to access despite hours of troubleshooting with support. This product is not release-ready; it’s an alpha version that needs several more iterations

### 1/5 — Total rip off

*2025-06-03*

Costs $10/mo to use the device at all. Not worth. Stay away

### 1/5 — Basic functionality broken

*2025-06-01*

None of the biofeedback & mindfulness sessions work. There's no audio beyond a voice saying the title and it doesn't work at all if you turn off "show heart rate & track HRV".  To do the onboarding you’re forced to watch videos and ads to get the information.  No written text is provided. Someone needs to QA the app before release.

### 1/5 — No way to log in except Google or Apple?

*2024-11-13*

I am not seeing a way to sign up and log in with my email and a password, the only way is with a Google or an Apple password and I prefer not to use those.

### 1/5 — No way to log in except Google or Apple?

*2024-10-13*

I am not seeing a way to sign up and log in with my email and password.

### 2/5 — works okay but terrible UI

*2024-07-03*

There is a lot to be desired from this app still. I’m surprised it is such low quality given the expertise of the team.

For example:
-  in the biofeedback session it should show the time elapsed/remaining. 
- The “feedback” HR graph is awful and doesn’t show the interpolated curve, just some stepwise measurements. It could really use auto scaling too! Not much better than paced breathing.
- I have slightly larger fonts enabled in my OS settings and it makes this app look awful. Lots of the text gets cut off, but I figured out I can scroll.

### 1/5 — Makes you log in every day

*2024-01-09*

Even when ticking “remember me” you still have to log in manually every day, and app often crashes after a reading when typing 😤

### 1/5 — Just another thief masquerading as a tech company

*2023-05-17*

There is a list of approved devices on their website. There is a number of . The Viiiiva (stupid name, I know) is listed on their website as approved, It is connected to my phone via Bluetooth 4.0 and when I try to use the app it doesn’t work. I suspect it would work perfectly if I spent another $50 on their proprietary measuring device. I don’t have the money. I’m trying to treat my ptsd while still paying off my cancer bills.

### 5/5 — Victoria

*2022-06-16*

I started using the biofeedback training about 6 months ago and have seen my HRV steadily improve! I also love to use the morning reading to gauge what I can take on that day. It’s an amazingly accurate indicator of what’s happening in my life both emotionally and physically. I feel empowered by this information and have built increased capacity and resilience using the mindfulness and biofeedback components. Thank you for such a useful app!
