# Connected health device companion

The app beside a connected device: readings, context, and sharing that people actually use.

**Who it serves**

Device makers and care programs whose product is only as good as the companion app.

Illustrative example

-   Phone: today's readings with device status
-   Web: thirty-day trend and care-team sharing

The problem

## What goes wrong  
without it.

A device that measures well still fails if pairing is fragile, readings arrive without context, and sharing a summary with a clinician takes screenshots and email.

## What the product would do

1.  Pair and manage the device, including battery and firmware state.
2.  Show readings over time with the context needed to act on them.
3.  Share a summary with a clinician or caregiver, with consent controls the user understands.
4.  Prompt for missed readings; stay quiet when nothing needs attention.
5.  Export a dated report in a format a practice can file.

## Decided before any screen

-   What the data model owes to standards, so observations can reach care systems later without a rewrite.
-   Which readings justify a prompt and which never should. Alert fatigue is a product decision, not a setting.
-   Where consent, sharing, and revocation live, and how they are evidenced.

Why it suits the method

## Specified once.  
Built in parallel.

Well-bounded screens behind one strict data contract. The record and the sharing rules are specified once; the many views of them can be built in parallel and verified against the same acceptance criteria.
