Which sensors can we use?

Bluetooth heart rate sensors that send RR intervals, the time between heartbeats. The Polar H10 chest strap is the one we recommend. If chest straps don't suit your clients, tell us what you use and we'll test it as part of the pilot.

What do staff need to run a measurement?

Chrome or Edge on a laptop, or Chrome on an Android tablet or phone. Live measurement does not work on iPhones or iPads.

Does a higher reading after a session prove the session worked?

No. An HRV change on its own does not establish that a method caused a benefit. Breathing, posture, time of day, and measurement conditions all affect the readings. What a consistent routine gives you is comparable readings across many sessions, which is a far better basis for a conversation with a client than a single number.

Is Open HRV a medical device?

No. Open HRV supports measurement and analysis for wellness and research workflows. It does not diagnose conditions or replace professional medical judgment.

For wellness centers and the brands that equip them

Show every client how their body responded.

Open HRV adds a short heart rate variability reading before and after each session, and keeps both in the client's record, session after session.

BeforeAfterExample data

A measurement routine that fits around a session.

The same four steps for every client and every member of staff, so readings stay comparable from one visit to the next.

Step 1
Open the client's record
On a laptop or Android tablet at reception or in the treatment room.
Step 2
Measure before
A resting reading of about three to five minutes with a Bluetooth heart rate sensor.
Step 3
Run your session
Stop there, or keep recording live to watch the readings through the whole session.
Step 4
Measure after
Both readings are saved to the client's record, ready to compare with every earlier visit.

What your center works with.

Some of this is in the product now. The rest we build with the centers that pilot it, around how their sessions actually run.

In the product today

A record for each client: Every reading sits under the client it belongs to. Personal details are stored encrypted.
Live readings with a signal check: Staff see heart rate and HRV as they record, and a quality indicator flags a noisy signal.
Full analysis after the session: Time-domain, frequency-domain, and non-linear HRV metrics, with a CSV and a PDF report for each recording.
Measurements from home: Send a link so a client can record with their own sensor between visits. It lands in their record.

Built with pilot centers

Scoped with you at the start of a pilot.

A before-and-after comparison for each session, like the example above
Your logo and colors on reports and the client view
A simpler screen for front-desk staff and for clients measuring at home
Sensor testing for your setting, including alternatives to chest straps

Start with one center.

A pilot is a fixed, paid project with a clear end. Pricing depends on your session volume and what we build for you, so we quote it per location.

Running several centers, or supplying equipment to them? We start with one location and plan the rest from what it shows.

Ask for a pilot proposal

Scope: One location, eight weeks.
Before we start: We agree what you want to learn and how we'll both know it worked.
Setup: A setup call, a walkthrough for your staff, and sensor checks on your equipment.
During: A named contact for questions, and fixes while the pilot runs.
At the end: A review of what the readings showed, then your decision about more locations.
