FibriCheck Health is a module in the FibriCheck app that can give you extra information about your heart health. It’s available for Essential, Premium and Free Trial users.
Overview of the FibriCheck Health metrics
| What does it show? | What does it mean for you? | How can you unlock it? | |
|---|---|---|---|
| Morning HRV | It shows the tiny variations in time between your heartbeats. | More variation generally means your body is adapting well to stress, sleep, or activity. | It becomes available after your first morning measurement (between 5:00 and 10:00). |
| HRV-CV | It shows how consistent your HRV is from day to day. | It’s better to have a stable recovery pattern than a fluctuating one. | It becomes available after 5 morning measurements (between 5:00 and 10:00) within a 7-day window. |
| Heart age | It shows an estimate of how your heart is doing compared to your biological age. | Slow-moving number that shows you whether your heart health is improving or not. | It becomes availableafter 5 regular (green) measurements in the last month |
| Resting heart rate | It shows your heart rate when you are fully at rest. | Keeping track of it over time shows whether your fitness is genuinely improving. | It becomes available after you log sitting or sleeping as your activity |
Good to know:
- We only use regular heart rhythm results
Irregular (orange or red) or low-quality (blue) measurements are never used. - We need you to measure on a daily basis
When you miss a week, your health values will be blurred because we can’t update them.
The FibriCheck Health metrics explained
Heart rhythm variability (HRV)
Heart rate variability is the small variation in time between each heartbeat. More variation generally means your body is adapting well to stress, sleep, or activity. It's a live read on how your heart is coping with daily stress, in all its forms and is one of the clearest signals of how your heart is doing today.
To get the most reliable HRV result, it’s best to take a measurement between 5AM and 10 AM, ideally right after you wake up and before you’ve had coffee or started moving.
Every day, we'll ask a few quick questions about sleep, alcohol, exercise, and how you're feeling. This way, you can see how your activities and habits connect to your HRV.
Heart age
Once you completed 5 measurements, your heart age is unlocked. It shows an estimate of how your heart is doing compared to your biological age. This number is built from your measurements and HRV, and shaped by your daily habits. It's a wellness indicator, not a medical diagnosis.
Better sleep, regular movement, less stress, and consistent morning measurements. They all show up in your heart age over time.
Your heart age updates as you keep measuring, and your habits change. It shifts gradually, not overnight. Checking in regularly shows you what's working, and gives you an early, motivating signal to keep going.
Resting heart rate
Resting heart rate is how many times your heart beats per minute, when you're fully at rest. It reflects how efficiently your heart works.
A lower resting heart rate generally means your heart doesn't have to work as hard to keep a steady beat. This is a sign of better cardiovascular fitness.
Your resting heart rate is only calculated when you log sitting or sleeping as your activity, so it reflects a genuine baseline, not a reading affected by movement.
Unlike HRV, resting heart rate typically shifts slowly, over weeks, not days. Keeping track of it over time shows whether your fitness is genuinely improving.
