Built for real product work

From first payload to production scale.

The provider-specific complexity stays inside the component. Your app gets typed data, explicit lifecycle controls, and room to grow.

New in v0.5

Build against believable data before the first device connects.

Synth creates deterministic workouts, sleep, heart rate, HRV, SpO₂, steps, recovery, and summaries in the exact normalized model used by live providers.

Developer experience

TypeScript from OAuth to query.

One client for connections, events, time series, summaries, sync, backfills, and lifecycle cleanup.

Operationally ready

Safe sync and clean exits.

Durable backfills, deduplication, provider-aware summaries, and a cascading delete path for user data.
