Serenity is a calm place on your iPhone to check in with yourself. Log how you feel with a quick rating and a few tags, answer a short daily check-in about sleep, energy and stress, and write a journal entry when you want to go deeper. The Home screen pulls it together into a simple wellness score and shows how things are trending.
When you need a moment, there are short guided exercises for breathing, meditation and grounding, and a supportive chat that suggests what might help based on how you've been feeling. Everything stays on your device and there's no account. Serenity isn't therapy, and if you describe a crisis it points you straight to people who can help.
