Common questions from fitness and wellness app developers
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.
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.
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.
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.
