This app provides fitness and lifestyle insights for informational purposes only, helping users better understand their activity, recovery, and training patterns over time.
The app aggregates fitness, activity, and sleep data to present clear, non-clinical metrics and trends related to daily readiness, training load, and recovery. These insights are designed to support awareness and consistency, not to diagnose or predict medical conditions.
Vitals & Recovery
The app tracks Vitals, which combine:
• Readiness — a daytime recovery indicator based on recent activity and physiological trends
• Sleep — a nighttime recovery indicator derived from sleep duration, efficiency, and consistency
Together, these metrics help users observe how training and rest patterns relate to perceived recovery over time.
Training Guidance
The app includes a workout recommender that suggests weekly and daily training mixes aligned with widely accepted fitness and longevity-oriented best practices.
Daily recommendations may include combinations of:
• Higher heart rate activity
• Lower heart rate activity
• Strength training
• Rest or lighter days
Recommendations adapt based on recent training history, progress, and fitness trends. All suggestions are informational and optional, and users remain fully in control of their training choices.
Advanced Workout Analysis
Workouts are analyzed using fitness-focused metrics such as:
• Time spent in heart rate zones
• Training distribution trends
• Heart rate patterns over time
• Informational AI-generated insights to help summarize observed patterns
These analyses are intended to help users better understand how different types of activity relate to their overall training balance.
Body Age (Non-Medical)
The app includes a non-medical Body Age–style score, designed as an informational, trend-based fitness indicator, not a biological or medical assessment.
This score reflects multiple fitness and lifestyle inputs across areas such as:
• Cardiovascular fitness
• Metabolic and physical activity patterns
• Recovery and sleep consistency
Key contributing inputs may include resting heart rate, VO₂max estimates, training time in different intensity zones, strength training volume, daily steps, lean body mass percentage, sleep duration, sleep efficiency, and sleep consistency.
The score is intended to support relative comparison and trend tracking over time, not medical interpretation.
Private, On-Device Coaching
On supported devices with Apple Intelligence enabled, the app offers a fully on-device, private health and fitness coach.
All interactions are processed locally, with no data leaving the device, allowing users to reflect on their goals, routines, and progress in a private and secure way.

Great app for tracking workouts I have a Bluetooth heart rate monitor it it seemly connected to the watch for easy phone less HR viewing. I searched for an hour trying to find an app with this functionality and this I the only one I found that was free.
Improved sharing to instagram with transparent content and direct to app dialog
Fitness score is more precise across historical data
Community URLs from web shares now work first time, no double tap needed
Multiple other functional and visual bug fixes and improvements
