Ask HN: Have you had any real benefits from apps like Headspace, Fabulous, etc?

There are so many apps which promise scientific benefits like relief from stress, better habits, etc.

Unfortunately most of them are free for only 7 days or 10 days and followed with a steep cost. I'm okay paying if there are any real benefits but the reviews are really mixed on the play store.

So just wondering what you guys think? Has any such app has had real life benefits? What do you think?
