Steps
- Open Settings > Notifications.
- Find App icon badge.
- Choose All notifications, Dismissed notifications or No badge.
- If your phone needs it, turn on Show a notification with app icons.
Good to know
- The number counts from the last time you opened the app.
- The badge needs the notifications permission. See "How to allow notifications so alarms and the app badge work".
- Some phones, such as Samsung, show badges only while a notification is present.
