After months of development, we're shipping our biggest Whistle update on May 26th. The centerpiece is a fully agentic AI coach that builds personalized training plans for almost any fitness goal. Thanks to multiple sub-agents, a custom memory system, and our own training intent framework, the coach pulls in your training load, sleep, recovery, and even the weather, adapting to your schedule and preferences rather than handing you a rigid plan. Workouts sync directly to your Apple Watch with custom targets and guidance, ready to start. Privacy was a core design decision from day one: the coach asks permission before accessing any data, and nothing is ever stored on our servers.
