# Roadmap

> What is coming to the NEUROFIT Vitals SDK after 1.0.0.

Items here are in development or planned. None carries a committed date, and licensees under maintenance receive
them as SDK updates when they ship. Ask [contact@neurofit.app](mailto:contact@neurofit.app) if one of them
matters to your timeline.

## Coming soon

### Estimated VO2max from a 3-minute stair test

A guided 3-minute stair-climb test that uses the same fingertip reading before and after the effort to estimate
VO2max, the standard measure of aerobic fitness. Same on-device design, same result type, a new session kind.
Heart rate recovery after the effort is part of the same work.

## In development

* **Repeatability thresholds for `VitalsChange`.** The "beyond typical measurement variation" constants (10 ms
  HRV (RMSSD), 5 bpm heart rate, 2 brpm breathing rate) come from the chest-strap agreement study. A back-to-back
  repeatability analysis is under way and will replace them with same-person, same-session figures.
* **Validation study growth.** More participants, with a focus on Monk skin tones 7, 9 and 10, and a blind test of
  the finished system on new participants. The [Metrics](/metrics) page is updated as the report is.

## Planned

* **Camera preview views for the wrappers.** A React Native component, a Flutter widget and a Capacitor view for
  the fingertip preview, so wrapper apps can show the red glow without native code.
* **Java sample app** alongside the Kotlin one.

## Not planned for the SDK

Anything that needs a network call or remote configuration. The SDK stays on-device; those layers belong to your
app.
