Gorgeous app, my favorite journaling app now!

Shuren Lee
The UI design is stunning, from the subtle gloom of the cards to spacial text-image composition, everything is just gorgeous. The interaction is smooth and stable, very thoughtful on user experiences.And the fact that this app takes up only 6MB is phenomenal. Hope for customizable theme (like background/text color) and PDF export.

Past journal lost
Jan 14

I like this the UI design, it could be a good journal app, however have faced two times my journal gets lost. The first time happens in the beginning of 2025, I suddenly found out that all my 2024 journals disappears. Very frustrating.The second happened just now, I wrote something in the morning and switched to some other app. In the evening I found what I wrote gone. I have to make a decision to move to other options this time. If it keeps lost my journals it is not usable.
