I'd like to monitor my heartrate throughout the day, and do some analysis/visualisation of the data myself. As such, I'm hoping to find something that meets the following requirements:
Must-have:
- Not the "contact" version where you have to manually touch the watch to take a reading
- Stores data and exports data to a text format, or a third party API that can do this
Nice-to-have:
- Strapless
- Rechargable
Has anyone else had experience with solutions for this sort of experiment?
