Fitness & Wellness Use Cases

Recovery Tracking

Daily morning HRV measurements to assess recovery status and readiness to train. No wearable sleep tracking needed.

Training Load

Monitor how training affects HRV trends over time. Help users optimize training and avoid overtraining.

Morning Readiness

Quick daily check-ins give users a readiness score based on resting heart rate and HRV.

Pre/Post Workout

Compare vital signs before and after exercise to quantify workout intensity and recovery.

Stress Assessment

HRV-based stress scores help users understand their stress levels and track improvement.

Breathing Exercises

Real-time feedback during guided breathing and meditation. See impact on heart rate and HRV instantly.

Fitness App FAQ

Common questions from fitness and wellness app developers

What vitals are most relevant for fitness apps?

Heart rate, heart rate variability (HRV), and respiratory rate are most commonly used. HRV is particularly valuable for recovery tracking, stress assessment, and training load optimization.

How accurate is the technology during exercise?

Our technology is optimized for resting measurements. For during-workout monitoring, we recommend resting captures before and after exercise. We are developing motion-tolerant algorithms for future releases.

Can this replace wearables in fitness apps?

For many use cases, yes. Daily morning HRV, recovery assessments, and wellness tracking work great without wearables. For continuous during-workout monitoring, wearables may still be needed alongside our technology.

What is the developer experience like?

We offer SDKs for iOS, Android, and web with clear documentation and sandbox access. Most developers start with our native app for immediate access, then integrate our SDK in days. We provide sample apps and dedicated support.
