Take your FibriCheck readings. Note what was going on. Compass finds what the possible cause is of your symptoms.
Compass does not diagnose. It organises your data so you and your doctor can see the patterns clearly. In plain language, never a medical conclusion.
Most investigations run 4 to 12 weeks, depending on how often you have symptoms.
Measure daily, and also when you have symptoms.
Sleep, stress, coffee, meals, symptoms…
Compass weighs episodes against lifestyle, over time rather than one moment.
A structured report that links your symptoms to their lifestyle, grounded in known science, and ready for your doctor.
One measurement is one moment. Compass lines your episodes up against what your days looked like, and focuses on the connections research already links to heart rhythm, like alcohol, sleep, stress and caffeine. So the patterns it shows you are the ones known to matter, not chance.
Your Compass report shows what your episodes correlate with. The clinical findings live in your FibriCheck report. Together they are structured, readable, and built to walk into an appointment with.
The lifestyle that your symptoms tended to follow.
In plain language, never a medical conclusion.
Suggested next steps, ready to share.
And if no clear trigger stands out, that is a useful answer too. It tells you and your doctor something as well.
Compass compares the times you had an irregular rhythm against the times you did not, using only your own data. It checks what tended to come before your episodes — caffeine, poor sleep, stress, alcohol — and whether each shows up more often before an episode than by chance. Compass only highlights a link once it has seen it enough times to be reasonably confident.
It uses a case-crossover design, an established method in medical research for studying what triggers health events.
No. Compass is an organised logbook for your heart. It does not diagnose. It gathers your measurements and context into clear insights you can discuss with your doctor. The decision about what it means stays with you and your doctor.
That still helps. A result of no obvious pattern rules things out and gives your doctor a structured starting point instead of a vague complaint. Compass cannot explain every cause, but it can help you see what is and is not connected.
No. Not every rhythm disorder or symptom has an explanation that can be found this way, and Compass will never pretend otherwise. But where there is a real relationship between your episodes and something in your daily life, Compass is built to bring it to the surface.
No. Compass is in addition to your normal care, not a replacement. If anything urgent appears in your FibriCheck measurements it is handled the way it always is. If you ever have severe or sudden symptoms, seek urgent care and do not wait for Compass.
Yes. The Compass pilot is free to join and you can leave at any time. It is clearly labelled as a test, and your feedback shapes what FibriCheck builds next.
Try Compass first and start making sense of your symptoms. You'll get free access to Compass, a structured report to share with your doctor, and the chance to shape a tool built for people like you. Your feedback can make a difference! Rough edges are expected, but your data stays yours and you can leave at any time.
We've received your details and will be in touch as we open the next round of Compass pilot testing.
