Intelligent Readiness: We use your Apple Health data (HRV, Sleep, Activity) to dynamically adjust today's intensity or duration. If you’re fatigued, Theron gives you an easier session.

Scientific Foundation: Training protocols are based on peer-reviewed sports science to ensure optimal periodization and peaking for your target race.

Dynamic Plan Adjustments: Missed a swim? Your plan immediately restructures the upcoming week to ensure you stay on track without double-counting or unnecessary stress.
