Journal App: Mood Diary

About this app

Journal App makes checking in with yourself a simple daily habit. Log your mood with a single emoji, jot down what happened, and track anything else that matters: sleep, exercise, medications, or custom categories you create yourself.

Over time, your entries turn into insights: a colorful calendar of your moods at a glance, and trends that help you spot patterns in your mental health and habits.
