Signal Coach

Personal nutrition, training and recovery coaching over WhatsApp.

Signal Coach is a private beta. Members message the coach in ordinary language to log meals, weight and workouts, and receive daily calorie and protein targets that adapt to what they actually eat and how their weight is trending. With a member's permission it connects to WHOOP to factor sleep, recovery and strain into that day's guidance.

Wellness guidance only Signal Coach is not a medical device, doctor, registered dietitian, or emergency service, and it is not a substitute for professional medical advice. Do not use it for emergencies, diagnosis, medication changes, or treatment decisions.

How to join

Membership is by invitation. There is no public sign-up: an invited member receives a link that opens WhatsApp with their invite code, and messaging the coach with that code is what creates their account. Anyone can ask the coach to stop messaging them at any time, and any member can ask for their data to be deleted.

Data

The coach stores what a member tells it and, where connected, the WHOOP metrics it uses to generate guidance. It does not sell member data or use it for advertising. The full detail is in the privacy policy.
