We are working on this. Measure doesn't show low frequency signals (eg
1hz-50hz) very well. This was a design trade-off at that point of time. We
can definitely do better than that.

There are other things also that I'd like to add to Measure (or to a
separate version of it) to make it better suited for health applications.
Suggestions welcome.
