Need a way to pull reports of just the AFib positive readings

I love the app & it’s been super helpful but there needs to be an option to pull the reports for when afib is detected rather than having to go back into every record to get afib trending. Other than that it’s a stellar app to have.

Useful for detecting irregularity

Yes it is a useful app. I am a doctor using this app on myself. I think the best way to detect Afib is with a long term cardiac monitor such as an event recoder. Doctors can best analyze the heart rythm witha 12 lead EKG with leads connected to various parts of the body. An alternative is a rhytm strip which records just one lead. Some watches can record a true rhythm strip by detecting the electrical voltage between two locations on the body, eg two hands. But if you do not have that technology available this Afib monitor is a good option. It records the pulse from the 'pulse oximeter' feature which is usually used to measure blood oxygen saturation. The light refected through the skin fluctuates as the blood vessels are filled with blood with every heart beat. The key is, that by examining this waveform you can see whether the beats are equally spaced. If not, you may be experiencing some kind of abnormal irregular heart rythm. If so you can seek more precise medical testing from a professional. So yes this is a valuable tool.
The advertising on the free version is very obnoxious, covering the screen, without any way of clicking the adds off. Really horrible advertising of the worst kind and it totally dominates the app.

What does the “stress meter” mean?

The little stress meter at the bottom that shows the little heart over “relaxed”, “normal”, “elevated”, or “High” Stress …. What is this measuring and what is it supposed to be telling me? I’ve looked on your website, on this App Store, and done extensive Internet search for info related to this app and can’t find anything that explains this. There’s times I have a 65-70 bpm heart rate, but still says my stress level is “high”. But I can’t find any info that tells me what that “high stress level” means. Is that stress on my heart? Is it measuring emotional stress? Is it measuring heart variability stress? Etc.

Developer Response ,

Thanks for your feedback! Don't worry for the stress message, It helps the user to track the physical fatigue level for long-term. We will add the explaining in the next version. Thanks.
