You can set the volume standards both on the watch or the paired phone.
To set it on the Watch:
- Open the Settings app
- Swipe with your finger, or turn the Digital Crown (the round button on the edge of the watch) to scroll down to “Sounds & Haptics”
- Ensure the Alert Volume is, say, 50%. Tapping on the speaker icons will lower or raise the volume of the alert. Alternatively, you can turn the Digital Crown to change the volume.
- Ensure Silent Mode is off.
- Scroll down to “Haptic Strength”. It has three settings: off, medium (1 bar), and strong (2 bars). Make sure it’s not off.
On the paired iPhone:
- Open the Watch app
- Tap “Notifications”. Scroll down the list of apps until you find Time Timer. Ensure its notifications are enabled (switch is green).
- Tap on General. Check that “Do Not Disturb” mode is off, or if you’re Mirroring iPhone, the scheduled time is out with the hours you’re testing the app.
- Tap the back button twice until the title bar reads “My Watch”
- Tap on “Sounds & Haptics”. Changing the Alert Volume here will produce a test click sound on the Watch. Note that setting the volume here doesn’t change the slider on the Watch, so it’s possible to have the Watch Alert Volume at 100% and the same setting on the iPhone at 0%, and you won’t hear anything. Setting Alert Volume to 50% should be sufficient.
- Check the “Haptic Strength” setting below “Silent Mode”. This setting mirrors the same on the Watch - changing it on the phone will immediately change it on the Watch and vice versa.
- Ensure Silent Mode is off. Like the “Haptic Strength” setting, this is mirrored between Watch and iPhone.
