Google Health 5.10: Delete Logs by Chat and Readiness Score

Learn how to delete Google Health logs by chatting with the Coach and understand the updated Readiness Score in version 5.10 for Android and iOS.

October 10, 2026 Yum News

Google Health 5.10 is a small but practical update that rolled out this week for Android and iOS. The biggest day-to-day change is the ability to delete certain logs by talking to the Health Coach. The Readiness Score also now pulls in more sleep signals for a more personalized daily number.

This guide walks through the new features using only details confirmed in Google’s release notes and Help Center pages. Menu names can differ slightly by device, so search Settings if a path does not match exactly.

What Google Health 5.10 actually adds

Version 5.10 brings three changes:

Delete logs by chatting with the Google Health Coach for daily entries you logged through the Coach (workouts, meals, weight, and symptoms). Medical records are excluded.
Readiness Score updates that use additional signals from your sleep for a more personalized experience.
Irregular Rhythm Notifications expanded to Japan on supported Pixel Watch and Fitbit devices.

The update is fully available on iOS and still rolling out gradually on Android. No subscription is required for the chat-delete feature or the Readiness Score itself.

Delete logs by chatting with the Health Coach

Previously you had to open a log detail screen and tap the trash icon. Now you can ask the Coach directly.

Open the Google Health app and tap Ask Coach (or the chat button). Type or speak a clear request such as:

“Delete the run I logged this morning.”
“Remove the breakfast I logged yesterday.”
“Delete the weight entry from today.”

The Coach confirms the action. It only works for daily entries you logged with the Coach. It does not delete medical records or data that arrived from a connected app or device without going through the Coach.

If the Coach asks for clarification (for example, which of two runs), reply with the extra detail. After it finishes, the log disappears from your history.

You can still delete the traditional way if you prefer. Open the log details and tap the trash can in the top right.

How the updated Readiness Score works

Your Readiness Score is a daily 0–100 number that shows how recovered your body is. It compares your recent data against your own baseline.

Google’s Help Center lists the main inputs:

Sleep — quality and patterns over the past week.
Heart-rate variability (HRV) — variation between heartbeats, measured overnight.
Resting heart rate (RHR).

In 5.10 the score uses additional sleep signals so the number better reflects how your sleep is affecting recovery. The exact new signals are not listed publicly, but the goal is a more personalized daily reading.

Score bands remain the same:

Score	Label	Meaning
65–100	High	Ready for harder effort
30–64	Moderate	Normal activity is fine
0–29	Low	Prioritize recovery

You need seven nights of sleep data before the first score appears. Consistent wear for about a month builds a stronger baseline.

View the score each morning in the Today tab or on supported Pixel Watch and Fitbit devices. A high score does not force you to train hard; it is one signal among others.

Set up Irregular Rhythm Notifications (Japan)

Irregular Rhythm Notifications analyze heart-rhythm data in the background while you are still or sleeping. The feature looks for signs of atrial fibrillation (AFib).

With 5.10 it is now available in Japan on Pixel Watch and Fitbit devices. Users outside Japan already had access on supported hardware.

To set it up:

Open the Google Health app.
Go to the Health tab.
Find the Irregular Rhythm Notifications option and follow the prompts.
Confirm your device is supported (check the Help Center list for the latest models).

The feature runs in the background. You receive a notification if it detects an irregular pattern. It is not a medical diagnosis; follow up with a clinician if you receive an alert.

Tips for using the Coach and Readiness Score together

Log workouts and meals through the Coach so the chat-delete option is available later.
Check Readiness Score before planning intensity. A low score after poor sleep is a useful reminder even if you feel fine.
Wear your device consistently at night. Missing sleep data delays or weakens the score.
If you do not want proactive Coach messages, open Settings → Coaching and choose No Coach insights. You can still chat when you want.
Medical records and data synced from other apps stay under the normal deletion tools in Your data in Google Health.

Troubleshooting

Coach does not delete the log. Confirm you originally logged that entry through the Coach, not through a third-party app sync. Try a more specific phrase (“the 5 km run this morning”).

Readiness Score is missing. You need seven nights of sleep data. Keep wearing the device overnight and check again tomorrow.

Irregular Rhythm option is absent. Confirm you are in a supported region and on a supported device. The Japan expansion is new with 5.10; older app versions will not show it.

Update not visible. Check the Play Store or App Store for Google Health 5.10. Android rollouts can take several days.

Conclusion

Google Health 5.10 makes two everyday tasks easier: correcting a mistaken log with a quick chat and getting a Readiness Score that better reflects your recent sleep. The Irregular Rhythm expansion is region-specific for now, but the rest of the update is useful on both Android and iOS.

Update the app, try the chat delete on a test entry, and check your morning Readiness Score. Small changes in logging and recovery signals compound over weeks of consistent use.
