Frequently Asked Questions

Is my data secure?

+

Yes. Antheartide uses AES-GCM encryption and stores all biometric data locally on your device.

What is the .antheartide file format?

+

It is a proprietary secure container used to share sessions between devices. It includes your raw data and metadata, protected by app-level encryption.

Do I need a specific chest strap to use the app?

+

No. The app works with any standard Bluetooth Low Energy heart-rate chest strap, with your Apple Watch via HealthKit, or with an optional iPhone camera reading.

What is HRV?

+

Heart Rate Variability (HRV) is the variation in time between each heartbeat. It is a powerful indicator of your body's recovery state and overall health.

How is HRV calculated?

+

Antheartide calculates HRV using the RMSSD method, a reliable standard for rhythmic evaluation.

Can I share data with a professional?

+

Absolutely. You can export PDF reports or share the secure .antheartide session file directly.

Which devices are supported?

+

Antheartide supports iPhone 11 and newer. For heart-rate accessories, any standard Bluetooth Low Energy (BLE) compatible chest strap will work, in addition to Apple Watch via HealthKit.
