Great app for visualizing the heart rate data

I had been looking for an app to be able to make comparative plots of the heart rate data from the watch.
Unfortunately the data itself needs some filtering introduced by watch position and measurement inaccuracies leading to sudden instantaneous variations.

Need the following enhancements.
- 24 hour overlay plots for selected days, weeks etc.
- Manual identification and filtering out the positioning errors, to avoid false positives for arrhythmias.

Thanks again for a great app.
