Technology media Android Headline published a blog post yesterday (July 18), reporting that Google plans to launch "Notification Cooldown" and a new strength training experience on the Pixel Watch 4 smartwatch.
In the March 2025 Pixel feature update, Google launched a new feature called "Notification Cooldown" for Pixel smartphones.

The latest news says that this feature will be extended to Pixel Watch 4, and may be further extended to other smartwatches through Wear OS 6.
IT Home Note: On Pixel phones, this feature will reduce the volume and minimize reminders for up to 2 minutes after receiving a large number of notifications in a short period of time. Notifications received during this cool-down period will still be displayed in the notification drop-down bar.
On Pixel Watch 4, this feature will dynamically reduce the tactile feedback of each notification to avoid continuous vibration of the user's wrist.
Strength training
Google is using Pixel Watch 4 to help users train smarter and introduce a new strength training experience. Users can use the new training plan builder (Workout Builder) to design their own training methods. This feature enables users to create interval training, warm-up and relaxation plans to maximize sports performance and reduce the risk of injury.
Pixel Watch 4 also offers Fitbit Premium services, where users can get AI-generated daily running suggestions to help users surpass themselves.
Users can perform these sequenced training with real-time guidance to reach their goals. After the training, Google will also provide advanced metrics and posture insights, including cadence, step length, vertical oscillation, ground contact time, vertical ratio and ground contact balance.
