Data Platforms & APIs

The connective tissue of the field: device APIs that expose data on request, health platforms that sync workouts and vitals across systems, and the open file formats and wireless protocols beneath them. These technologies decide whether data from many sources can be combined into one coherent picture, and they shape what developers can build at all.

Data Platforms & APIs technologies

A living interface to device data.

Device API

A documented interface that lets a tool request data from a device on demand, in a predictable structure, with clean authentication. Where a file format is a static agreement, an API is a living one. The quality of these interfaces shapes what an ecosystem of third party tools can become, and every hour a developer does not spend reverse engineering is spent on something users see.

Cloud or local service

Workouts and vitals, synced.

Health Data Platform

A system that syncs workouts and vitals across phones, watches, and sometimes clinical records, acting as a central store many apps can read and write. The convenience of one coherent history comes with a duty of stewardship, since the platform concentrates intimate data whose location, access, and retention become central design questions.

Cloud and mobile OS

A shared language for sessions.

Workout Data Format

An open file standard for recorded sessions: an agreement about which fields exist, what they are called, what units they use, and how time is represented. When two systems share it, one can read the other's output without custom code. A merely adequate format with broad adoption reshapes the field more than a better one that stays niche.

Open file standard

How devices connect at all.

Wireless Protocol

The connectivity standards that let a sensor pair with a phone or gateway in the first place, governing how devices talk before any data can mean anything. Where data formats decide what messages mean, protocols decide whether a connection happens at all. Their adoption quietly determines which devices can work together across vendors.
