How it works
Delta reads your biometric data, scores what it means for today, and delivers a clear morning brief — so you always know what to do.
Connects to Oura Ring, Apple Health, Peloton, and more — pulling sleep, HRV, readiness, workouts, and activity into a unified daily picture.
Proprietary algorithms compute daily scores for recovery, acute and chronic training load, and session strain — contextualized to your baseline.
Each morning, Delta generates a concise coaching brief: what your numbers mean, whether to push or recover, and what to focus on today.
Log meals conversationally — just describe what you ate. Delta parses macros and calories and keeps a running daily tally alongside your other metrics.
Integrations
Delta reads from your existing health ecosystem. No new hardware required.
Privacy
Delta collects health and biometric data solely to generate your personal coaching briefs. Your data is encrypted in transit and at rest, stored on infrastructure hosted by Supabase (AWS). It is never sold, rented, or shared with advertisers or other third parties.
The only external processor that touches your data is Anthropic (Claude AI), which receives anonymized daily metric summaries — not raw health records — to generate brief text. You can disconnect any integration or delete your account and all associated data at any time.
