Vibration Strength of Meditation App

The vibration when starting or ending a meditation activity is obnoxiously strong (maybe this is standard for all activities?). It doesn't seem to be affected by the watch's vibration level settings or have its own setting to control it. Is there anything I can do to turn it down or turn it off?

I would be willing to write my own meditation app with the controls I want, as long as it would register as a meditation. Is that an option? Obviously it would be a last resort and I would like to avoid going that far...
