Apple Watch Ultra 3 VS Peloton Tread+

Apple Watch Ultra 3 Peloton Tread+
Verdict DROP IT DROP IT
The Reality The feature has a real, documented history of simply not being available to US buyers. After the US International Trade Commission ruled the blood oxygen sensor infringed two Masimo patents, Apple disabled blood oxygen sensing on US-sold Apple Watches in January 2024 to keep selling the watch at all, and it stayed off for roughly a year and a half. In August 2025 Apple restored a redesigned version -- but the workaround processes the sensor's raw data on a paired iPhone rather than the watch itself, and results can only be viewed on the iPhone, not the watch face. The ITC formally closed the case in April 2026, ending Masimo's ability to revive the ban, but the underlying legal fight ran for over two years. CPSC's official recall record documents a serious real-world hazard: the Tread+'s rear opening could pull under an adult, child, pet, or object during use. Peloton received 72 initial reports of pull-under incidents, including the death of a 6-year-old child and dozens of other injuries such as broken bones, serious cuts, and a brain injury, before the May 2021 recall. By the time the recall was finalized, the total had grown to 351 incident reports, including 90 injuries in addition to the one death. CPSC and Peloton jointly announced the recall of roughly 125,000 units, and Peloton offered full refunds through November 2022. In 2023, CPSC approved a rear-guard repair as an additional protective measure for the same entrapment hazard.
SHORT ANSWER

Apple Watch Ultra 3: Apple Watch's blood oxygen feature was legally disabled for US buyers for about 20 months (January 2024-August 2025) after Apple lost a patent case to Masimo, and its restored version now only works by processing data on a paired iPhone rather than the watch itself.

Peloton Tread+: CPSC's official recall record shows a 6-year-old child died and 90 others were injured after being pulled under the Peloton Tread+'s rear opening, leading to a 2021 recall of roughly 125,000 units and a 2023 rear-guard repair program.
