freddy connects the health and fitness data you already track (wearables, rings, CGMs, sleep trackers, and training platforms) and makes it available to ChatGPT. Ask about your sleep, recovery, training load, heart rate, steps, or workouts and get answers grounded in your own history. Connect a source once and freddy keeps it in sync and normalizes it across devices, so every conversation can draw on your real data. Your data stays private: it is accessible only to you, revocable at any time, and never sold or used for advertising.

Skills 3
- connect-a-source
Use when the user wants to connect a wearable, ring, CGM, training platform, or gym log to freddy, or asks why a newly connected source shows no data yet. Not for disconnecting or for querying data.
- long-term-trends
Use when the user asks how a metric recorded in their freddy account changed over months or years — history charts, progress since a date, seasonal patterns, year-over-year comparisons. Not for a single week (use weekly-health-review).
- weekly-health-review
Use when the user asks for a weekly summary or check-in of the sleep, heart, training, or body data recorded in their freddy account. Not for multi-month or multi-year questions (use long-term-trends) or single-metric lookups.
Things to ask
- “How did I sleep this week?”
- “Show my resting heart rate trend, week by week”
- “Give me my weekly health review”
