Right now, users can only access the values presented in the app itself and not the raw waveform data.
Unfortunately, we are unable to share raw waveform data this at this time.
At this time, we don't have a way to export customer data, but are coming out with an API Q1 2019 that will give access to the same data displayed in the app.
We expect to release an export functionality around the same time, though we aren't sure how it will look yet.
If you’d like, you can sign up to be notified when this is available here: http://biostrap.link/api-notify
In regards to an SDK, we currently do not have one available, but with enough interest may consider in the long term.
