        "heading": "When to choose RingConn Gen 3",
        "body": "Gen 3 combines a larger size range, vibration alerts and a portable charging case. Its longer battery estimate matters if you want the ring on through several nights without thinking about a dock. It is more expensive in the reference dataset and its vascular insights are not diagnostic measurements."

        "heading": "When to choose Amazfit Helio Ring",
        "body": "Helio is the lower-reference-price way to add a ring to an existing Amazfit setup. It can make sense if you know which Zepp trends you want and one of the three sizes fits. Without that ecosystem or a verified local offer, the low reference price is not enough to recommend it."
      },
      {
        "heading": "What would change our choice?",
        "body": "Decide whether you are buying a primary overnight tracker or supplementing a watch. That question changes how much the charging case and longer range are worth. Neither battery estimate establishes better accuracy; for medical concerns, do not use apnea patterns, vascular trends or recovery scores as a substitute for professional assessment."
