What's New in TensionRadar

1.3.0

October 29, 2026

New in Trends: Week in Review. See separate weekly summaries for SDNN, RMSSD and resting heart rate, with recorded-day coverage and clearly marked missing days. Compare the last seven completed days with the previous week when enough data is available. Understand your heart rate at a glance. See the measured heart rate and resting rate together, with a clearer explanation of the difference. Matching wording across iPhone, Apple Watch and heart-rate widgets makes readings easier to compare. The score breakdown also adapts better to larger text.

FAQ

What is the TensionRadar wellness score?

The 0-100 wellness score is an estimate based on your personal HRV history, with heart rate included when available. It uses references for the same HRV statistic and time of day to provide context. The score is not a diagnosis and does not directly measure emotions.

Does TensionRadar require an account?

No, TensionRadar does not require an account to use its features. All health data is processed directly on your devices, ensuring your privacy.

What devices is TensionRadar compatible with?

TensionRadar requires iOS 18 or later and an Apple Watch that records HRV. It is designed for use on both iPhone and Apple Watch.

How often is TensionRadar updated?

The app was last updated on October 29, 2026, with version 1.3.0. Apple controls when measurements and background updates arrive, so readings and alerts are not continuous or guaranteed to be immediate.

Can I purchase additional characters for TensionRadar?

Yes, additional characters beyond the included Nimbus are available through an optional Character Pack purchase, processed by Apple.

Is TensionRadar a medical device?

No, TensionRadar is a wellness tool and not a medical device. It does not diagnose or treat any conditions. Consult a healthcare professional for medical advice.

Does TensionRadar have ads?

No, TensionRadar does not contain any advertising or cross-app tracking. Your privacy and a focused user experience are prioritized.

How does TensionRadar handle my health data?

Health data is processed on your devices. TensionRadar does not send HealthKit measurements, HRV or tension scores, or journal content to third-party services like RevenueCat.
