Smartbands and/or APPs with FINE-detailed "heartrate" history.?
Inside APP i can view
1) active data to current seconds
2) history data down to minutes
I want to review data down to seconds. need it to better diagnosed medical (hard to diagnose need constant monitors just to hope to capture it)
I have Medical condition and need to review data after episodes. my problem is i caught/recorded health concern but need a greater detailed heartrate log. this it is a major tool (better than nothing when at DRs)
smartband RAM is only good for a day (data must be saved on APP or over-write)
