With a simple touch on the calendar or the + button, users can record the events of the day and choose from five levels of emotion. The app also offers customization options for emotions.

Additionally, users can set their own notification messages to remind them to record their day at a fixed time, helping them maintain a consistent diary.

Murmur also provides a statistics function, which displays the number of diary entries recorded for each period. This feature will be further updated in the future, promising more insights into users' recording habits.

Overall, Murmur offers a convenient and secure way to keep a voice diary. It is a user-friendly app that allows users to record their day, customize emotions, and view past entries with ease.
