I think sports chest straps get overlooked even talking about this space. DCraimaker is a very active and does deep statistical analysis and recording for comparing many types of chest straps and wrist straps. Worth checking out. [3] The polar H10 has been compared to medical grade heart rate monitors and has is as good if not better. https://pubmed.ncbi.nlm.nih.gov/31004219/ https://pubmed.ncbi.nlm.nih.gov/31004219/ shows an evaluation for EKG. Polar also has sdk to develop apps. It's the "gold standard" but there have been more and more advances in the space. But the polar h10 has stood the test of time. If you're into fitness, and happen to have a polar H10 you can get tons of data from just wearing the strap overnight. Via this recommended android app. It supports mqtt as well. You can see live or you can record to file. There's no cloud involved and you can export directly from app. https://play.google.com/store/apps/details?id=com.j_ware.polarsensorlogger https://play.google.com/store/apps/details?id=com.j_ware.pol... [1] My tried and true app I have been using for workouts that's also gives me a Pulseometer RR. It doesn't do EKG but I have recording of over 18 hours no problem. Its a little out of date, in terms of not getting updates. But it is solid. It also does hrv and again local exports to csv. https://play.google.com/store/apps/details?id=com.beetlesoft.pulsometer https://play.google.com/store/apps/details?id=com.beetlesoft... [2] Chest strap = EKG, wrist! = ekg as it's optical *excluding the apple watch, however chest/electrodes will always be accurate than wrist/optical sensory not to mention battery life. [1] Details SUPPORTED: Verity Sense: - HR, PPi, Accelerometer, Gyro, Magnetometer and PPG OH1: wrist - HR, PPi, Accelerometer and PPG H10: Chest - HR, RR, ECG and Accelerometer H7/H9:CHEST - HR and RR Application also supports sensor data forwarding using MQTT-protocol. -- [3] https://www.dcrainmaker.com/2021/12/polar-h10-heart-rate-monitor-very-long-term-in-depth-review.html/amp https://www.dcrainmaker.com/2021/12/polar-h10-heart-rate-mon... -- I did leave off garmin products intentionally. They don't share ekg and at that price range I would suggest a Polar H10. Polar has a an sdk available for their products. I found one but study but there's plenty to validate that it is indeed medical grade if you search. I know many sports fitness studies that have used polar H10. You need bluetooth for ekg data. Ant+ only does hrv (with app), RR and basic HR data. If anyone has a windows PC app that logs and shows live EKG data for the polar H10, I would love to your suggestions. I have Golden cheetah and have experimented with android emulators but most seem to lack a proper bluetooth stack.
