Maum Diary is a private, offline-first emotion journal designed to help you understand your emotional life over time. Record how you feel each day, write a short note, and watch your emotional patterns emerge through beautiful visualizations - all without ever sending a single byte to a server.
KEY FEATURES
Daily Emotion Logging
Select from a range of emotions to describe how you feel today. Add a one-line journal entry to capture the moment in your own words. Use custom tags to organize entries by themes like work, relationships, or health.
Emotion Heatmap
See your emotional history at a glance on a calendar heatmap. Each day is color-coded by emotion, so you can immediately spot patterns, cycles, and shifts in your mood over weeks and months.
Weekly and Monthly Summaries
Maum Diary automatically generates summaries of your emotional week and month. Discover which emotions appeared most, how your mood shifted over time, and what moments defined each period.
Emotion Mosaic
Your recorded emotions come together to form a mosaic - a visual portrait of your emotional journey. The longer you use the app, the richer and more personal this mosaic becomes.
Emotion Replay and Insights
Replay your emotional timeline to revisit how you felt day by day. Gain insight into recurring patterns, triggers, and progress so you can better understand yourself.
Cute Character Companions
Choose a character companion that grows alongside your journaling habit. Each character adds warmth and personality to your daily recording experience.
PRIVACY FIRST - 100% OFFLINE

DARK MODE

MULTILINGUAL SUPPORT
