Guides to health wearables, scores and ownership

Start with heart rate variability

HRV is the signal most recovery scores are built on, and it is also the most widely misread. Two guides cover it: one on the measurement itself — how optical sensors capture beat-to-beat intervals, why the overnight window matters, and what separates a useful tracker from a frustrating one — and one on the physiology and the decisions, covering what raises and lowers HRV and how to use it when choosing whether to train.

Both are written to be read once and used for months. Neither requires you to own a Vybe device.

• What an HRV tracker actually does — measurement, conditions, baselines and how to choose a device.
• Heart rate variability, explained — the physiology, what moves it, and how to make training and rest decisions with it.

Choose a wearable and a business model

Three practical guides cover the questions people often discover after comparing sensor lists: what screenless design changes, how recurring wearable memberships affect access and cost, and what health-data ownership should mean in practice.

Each guide separates general evidence and official competitor terms from Vybe's own pre-launch product position.

• Screenless health wearables — comfort, continuous wear, battery and attention.
• Health trackers without a required subscription — total cost, cancellation and access to included insight.
• Health data privacy and ownership — HIPAA limits, consent, export and deletion.

Understand device claims and alerts

Six source-backed explainers address questions about available wearables: what WHOOP's recovery colors mean, the conditions behind Garmin solar and GPS battery claims, what titanium watch specifications establish, what a smartwatch ECG alert can and cannot tell you, and why ISO 22810 and MIL-STD-810H describe different things.

These are independent educational articles by Vybe Health, not official support pages, clinical reviews or laboratory tests. Third-party features do not describe Vybe's planned capabilities.

• WHOOP recovery scores — inputs, personal baselines and the limits of a daily percentage.
• Garmin Fenix 7 solar charging — exact models, operating modes and sunlight assumptions.
• Smartwatch ECG alerts — optical notifications, ECG recordings, inconclusive results and follow-up.
• Water-resistance standards — activity guidance, test conditions and the limits of a label.
• Garmin Forerunner 965 battery life — GPS modes, heart-rate settings and manufacturer runtime limits.
• Titanium smartwatch materials — case, finish and cover-glass distinctions without a scratch-resistance ranking.

Why these guides exist

Vybe's position is that people should be able to understand their own physiology without paying a monthly fee for the explanation. That applies to the education as much as the product: these guides are free, complete and not gated behind an email or a membership.

Vybe is pre-launch. Its intended ownership model includes wellness interpretation with the device and no required consumer subscription. Its stated privacy approach is Bluetooth-first data flow and consented sharing.
