ReJournal - Mood Logger

ReJournal is a free, open-source mood tracker and journaling app for Android. Unlike subscription-based mental health apps, it stores all data locally on your device, nothing is uploaded to the cloud. It is designed for anyone who wants a private, ad-free way to track daily mood, build habits, and identify emotional patterns.

"Your soul will feel rejuvenated"

• Log your mood (1–5 scale) along with Energy, Productivity, Stress, and Sleep sliders
• Tag your day with activities - pick from defaults, add your own custom tags, and give each one its own icon
• Rich text notes: bold, italic, underline, strikethrough, bullet/numbered lists, and custom text colors, plus a full-screen "Expand Note" mode
• Attach photos and voice memos to any day (that you can freely download to your own device)
• Mark a day as a Favorite with a tap of the heart icon
• Add some Micro-Wins everyday to boost your morale (e.x Made my bed, completed an assignment etc)
• Edit or delete any past entry, or back-fill a day you forgot to log

Day Logger 1 (The theme can be adjusted in settings!)

Day Logger 2 (Log your day in every way possible!)

• Month calendar view - each day colored by mood, depending on the emoji/color you picked, with small icons marking Important and Favorite days
• Year pixel view - your entire year at a glance, one tiny colored square per day
• Trend chart - a mood line graph for the current month, properly spaced by real calendar dates, with filters for mood, sliders, and activities. Tap it to expand into a full, swipeable view of the entire month
• Mood Constellation - turn your trend into a starry, artistic night-sky view where star size reflects how much you logged that day, and save it as an image
• Personality Tests - Do one of our many personality tests to learn more about yourself
• Mixtapes - Each week becomes a mixtape that you can view in organized shelves with other mixtapes. The average of your mood becomes the unique music genre for that week
