What are your favorite features in a self-help or wellness application?

I've been using different self-help apps recently for improving my focus and managing stress, and it got me thinking about what features truly make an app stand out. Some have beautiful interfaces, while others offer very specific guided practices. Personally, I find comprehensive progress tracking incredibly motivating, but I'm curious what other people value most. What are your favorite features or functionalities in a self-help or wellness application that genuinely help you make progress or feel better?
