Hmm. As I understood it the app is for mindfulness. It’s meant to actually just journal your thoughts and feelings throughout the day, nothing more.
The triggers, like workouts or recent activity are just a way to automatically get a prompt to journal about it. Say after a concert or maybe a hike up a mountain. If you allow journaling suggestions, that’s what you get.
When you customize it, you have the option to enable Activity, where it will suggest you journal after some kind of physical activity.
