Good News & Not So Good News

by Ashwin K Whitchurch

The not-so-good news first. We would like to address the main issue here: delayed shipping. On April 3, 2020, we posted an update about unprecedented shipping delays caused by the still-changing COVID-19 pandemic situation. India’s "21 day lockdown" was extended to 30 days, then extended again to 44 days. As things stand, it is scheduled to end on May 18th, 2020.

DHL and FedEx have now resumed limited shipping, and we are working hard to ship at least a few items as soon as possible—hopefully some time this week. If we succeed, we expect items to ship out to backers by the first week of June. We will post an update as soon as we are able to get things moving.

And Now For Some Good News…

We are happy to announce the launch of our brand new HealthyPi v4 app for Android and our first ever iOS app! You can download the app from the the usual places: The Google Play Store for Android devices and The Apple App Store for iOS devices.

The current capabilities of the app include the display of calculated vital signs, including the following:

  • Heart-rate
  • SPO₂
  • Respiration rate
  • Temperature

In addition, it includes a Live View that shows realtime ECG and PPG signals.

Needless to say, we will be updating the app as we complete development on additional features. If you would like app functionality that does not yet exist, please let us know, and we will include it if possible.

Toward the beginning of the COVID-19 outbreak, we were contacted by healthcare professionals in Europe and the US who were looking to learn more about how they might use HealthyPi v4 in their work. One possible application that we’ve been discussing relates to respiration monitoring using Impedance Pneumography and its potential to identify subtle changes in respiration before larger issues can be detected due to falling blood oxygen levels. This is just one idea, and there are likely others out there.

If you have any ideas as to how HealthyPi v4 might help make even the slightest difference in the global response to COVID-19, we would love to hear about it so we can support the effort however we can. Please write to us!
