A Pixel Drop is a quarterly software update from Google that enhances its devices with new features without needing any hardware upgrades. The latest Pixel Drop in September brings several software improvements to Google's smartwatches, though more significant Android updates are expected with Android 17 QPR1 later in the year. According to 9to5Google, all Pixel Watches starting from the second generation now include Gemini Personalization. This feature allows the built-in assistant to use past conversations and data from apps like Gmail, Calendar, or Photos to better respond to user requests. The newer Pixel Watch 3 and later models also gain a one-handed gesture—pinching with two fingers—to scroll through notifications when the other hand is busy. The Pixel Watch 4 receives an improved "raise to talk" gesture, which activates Gemini more precisely when the user raises their wrist to their mouth. The Pixel Drop also includes an updated Wear OS for the Pixel Watch 2, 3, and 4, though the Pixel Watch 5 had already received its update in early September. However, some of Google’s most significant health-related features are not part of this update. Instead, they are introduced through Health Guardian, a new platform announced in August with the Pixel Watch 5. This includes tracking insulin resistance trends, which estimate how well the body manages sugar over several weeks without requiring blood tests. These features will be available this autumn on the Pixel Watch 3, 4, and 5, as well as the Fitbit Air band. The Pixel Watch 5 is highlighted for its blood pressure tracking, which Google claims is trained using data from billions of minutes of cardiac and movement activity. Google emphasizes that these health tools are meant for general wellness and should not replace medical devices or professional advice. They caution against using them to manage diabetes or adjust treatment plans. While Apple has been offering blood pressure alerts since 2025, Google appears to have an edge with its insulin resistance tracking, which is still uncommon in other devices. However, in France, some of these features may not be available. Google has already limited certain functions of its Pixel devices in the country, known as the Hexagon in French, indicating potential regional restrictions on these new health features.
