Common questions

What's the time commitment?

We ask that you ship LungDx in production within 90 days. This isn't a strict cutoff - we want to ship with you. If your timeline shifts, just let us know.

What if my app isn't health-specific?

Apply anyway. We've seen compelling integrations in fitness, corporate wellness, sleep, and even research tools. The key question is whether respiratory metrics are meaningful to your users - if yes, we want to hear it.

Can my CTO talk to your CTO before we apply?

Yes - reach out here and we'll arrange it. Some of our best conversations start before the application form.

Is the SDK production-ready?

The SDK is stable and running in production for our first cohort of beta partners. We don't call it GA yet because we're still calibrating pricing and adding a few features. The measurement model itself is validated - the SDK APIs may have minor breaking changes before 1.0.
