- Visual Habits: Keep your momentum going with calendar streaks and writing indicators that visualize your consistency.
- Journal Reminders: Personalized notification manager with flexible timing and frequency to keep your journaling habit on track.
- Smart Search & Filtering: Instantly locate memories by searching through content and dates, or use the advanced filter menu to combine multiple tags (such as
@Johnand#Travel) to retrieve highly specific entries.
Secure & Styled
