Welly: Training & Recovery

Welly is the Apple Watch fitness companion that helps you train smarter, recover better, and understand what your body is ready for today.

It brings your training, recovery, sleep, stress, HRV, workouts, energy, and sunlight exposure into one system, then turns that data into clear coaching based on your personal baseline. Instead of generic averages, Welly learns what is normal for your body and helps you decide when to push, when to stay balanced, and when to recover.

Whether you are building fitness, managing fatigue, or improving your sleep, Welly helps you see how everything connects.

FEATURES

• Recovery coaching
Wake up to a personalized recovery picture built from overnight physiology, including HRV, heart rate, respiratory rate, wrist temperature, and blood oxygen trends. Welly helps you judge how ready your body may be for the day ahead.

• Adaptive training guidance
Get daily targets that adjust based on your recovery, training history, and current training load state. When your body is ready, targets rise. When you are under-recovered, Welly pulls things back.

• Training load and fitness tracking
See how recent training compares with your longer-term fitness base so you can understand whether you are in a productive, adapting, maintaining, fatigued, peaking, or overreaching state.

• Sleep analysis that adapts to you
Go beyond time asleep with sleep stage breakdowns, sleep scoring, schedule consistency, efficiency, and sleep debt. Welly measures your nights against your own history, not one-size-fits-all rules.

• Real-time stress and HRV
Track how your body shifts through the day using heart rate and HRV patterns from Apple Watch. Spot periods of activation, recovery, strain, and fatigue in real time.

• Energy tracking
See how sleep, stress, and activity shape your energy through the day with a continuously updated energy view that helps you time effort and recovery more intelligently.

• Workout insights
Turn workouts into meaningful effort data with heart-rate-based scoring, training context, and detailed workout analytics that feed your broader recovery and training picture.

• Sunlight and rhythm insights
Track daily sunlight exposure, morning light timing, and time to daylight after waking to better understand habits that support energy, routine, and sleep timing.

• Smart Alarm
Use Smart Alarm features designed around your sleep routine so waking up fits more naturally into your recovery habits.

• Timely, useful notifications
Receive morning summaries, stress alerts, training load updates, and progress signals that help you act on your data instead of just checking it.
