Productivity apps don’t work for me because of anxiety, what actually helps?

finally realizing my productivity issues aren’t about focus or planning and are about anxiety instead. when my body is on edge, no task system or cheat code is going to work for me. i see headspace recommended a lot, i have it, i use it, and it's fine for winding down at the end of the day, but my baseline is still too high. now i'm going down the nervous system regulating rabbit hole and am researching everything from apollo neuro to the leaply app while i'm looking for tools that focus on calming my stress response. what are the most helpful apps that help you focus and stay productive? not really into hacks, quotes, or anecdotes, but tools for anxious people like me.
