I appreciate moving away from cloud for personal health data like this.

Can you clarify why the ideal world you hint at would have the device sending any data to you?

I thoroughly applaud your approach.

I've been dealing with some cardiac issues that were brought on / exasperated by a covid infection, and it's been challenging finding solutions that let me monitor my own biometrics while hiking without sending anything to the cloud. It's shocking that it's a non-trivial endeavor to pair a medical grade wearable with a smartphone and get differentiated granular alarms / alerts for user defined events (BPM within user defined bands, blood oxygen levels below a certain threshhold, etc..)

If your python SDKs work wirelessly, I'd seriously consider creating a RPI based system to do those things and be able to leave the smartphone at home while I hike.

When you're ready with Aidlab 2, can you contact me? I work for a national health service and I'm keen to learn more, buy, and generate some public anonymized data sets. joel@joelparkerhenderson.com. Thanks and good work! <3

I watch "Quantified Scientist" (https://www.robterhorst.com/), in which Rob compares various watches and smartbands on how they measure sleep and heart rate - against golden standards.

By any chance, were you able to talk with him so he can measure it?

Any information on how comfortable the strap is? I am wearing a Garmin HRM Pro for one hour a day during workouts and it is not very comfy. I know a lot of athletes are moving to way less precise optical hand straps just because of the comfort issues with chest straps. I would not wear a chest strap for longer periods of time, unless I absolutely had to.

Nice idea. Wonder if you can use web Bluetooth to connect a web page directly to it?

Having glucose would be cool too.

Very commendable approach!

Are you using Movesense as the chest movement sensor per chance? I've been looking into breathing rate lately, but haven't made the jump just yet.

Plans for blood glucose?
