Overview
- DigiTimes reported Monday that Apple is planning a complete Apple Watch Ultra 4 redesign with a major sensor upgrade, though Apple has not confirmed the details.
- The report says a new high blood pressure notification is under FDA review and would use the optical heart-rate sensor to flag abnormal blood-vessel responses to each heartbeat, distinct from the hypertension alerts added in 2025.
- Taiwan-Asia Semiconductor, cited as Apple’s exclusive sensor supplier, expects large-volume orders beginning in July, a timeline that lines up with a typical September product launch.
- Market observers quoted in the coverage expect the redesign to lift Apple Watch shipments by about 20% to 30% versus 2025, which would reflect stronger demand for health-focused features if regulators clear them.
- The articles note Apple’s longer-term work on noninvasive blood-glucose monitoring that still needs government approval, and they frame Ultra 4 as the first big external refresh since the Ultra line debuted in 2022.
