Google Health 5.10 adds a chat-based way to correct daily entries logged through Health Coach. Instead of finding a mistaken workout or meal in the app, users can ask the coach to remove it in a conversation. The update is rolling out for Android and iOS, alongside changes to Readiness Score and expanded irregular rhythm notifications in Japan.
Health Coach can remove mistaken entries
Google says users can ask Health Coach to delete daily entries they logged, such as workouts, meals, weight, or symptoms. Its example request is: “Delete the run I logged this morning.” The feature is limited to daily entries and does not cover medical records, so it should not be treated as a way to erase every kind of health information connected to the app.
The change builds on Google's evolving Health Coach experience. Earlier, Google Health 5.06 added a setting to hide the AI coach from the Today tab. The new feature addresses a different problem: correcting information already entered, rather than changing how prominently the coach appears in the app.
Readiness Score uses additional sleep signals
Google says Readiness Score now uses additional signals from sleep data to make the result more personalized. The announcement does not specify which signals were added or how much they influence the score, so the update does not provide a detailed explanation of the revised calculation.
Irregular rhythm notifications expand to Japan
Google Health 5.10 also brings Irregular Rhythm Notifications to Japan on supported Pixel Watch and Fitbit devices. The feature checks heart-rhythm data while a user is still or sleeping for signs that may indicate atrial fibrillation (AFib). In Japan, users can set it up from the Health tab in the Google Health app.
The version 5.10 rollout began on October 9, 2026, and is expected to reach users in phases over about a week. Timing can vary by carrier and device. Google's official Google Health 5.10 announcement has the release details.
The deletion option also raises a useful question about how people manage information shared with AI health tools. Saganote has also covered OpenAI Health in ChatGPT and connected health data, alongside practical advice on protecting data when using AI chatbots.
