The Virtual Coach
It's like having a world-class trainer right in your pocket. Finish our onboarding, and you instantly receive a complete, customized program that adapts to you in real-time using cutting-edge coaching logic.
- Flexible Compliance Gates: Evaluates your calorie and macro consistency within range-based zones rather than demanding absolute perfection.
- Psychological & Recovery Triggers: Reassures you during sudden scale spikes, flags extreme calorie deficits, and warns of metabolic slowdown.
- Active Body Recomposition Hold: Holds macros steady if your lift volume and strength increase while weight stalls, letting you build muscle and burn fat.
- Supportive Ghost Check-Ins: Reaches out automatically with personalized support and advice if you stop logging, keeping you on track.
Beautiful Visuals & Biofeedback
Tracking your progress goes far beyond just body weight. We've designed gorgeous, interactive charts and logging tools to help you understand your biological trends at a glance, without administrative overhead.
- 7-Day Rolling Averages: Toggle between raw scale weight and a 7-day moving average to filter out daily water weight spikes.
- Subjective Biofeedback Tracking: Log daily ratings for sleep quality, energy levels, and hunger to stay in sync with your recovery.
- Interactive Charts: Visual representations of your macro distribution, progressive training volume, and strength milestones over time.
- Health Integrations: Seamless synchronization with Apple HealthKit and Google Health Connect.
