I really love how Akiflow looks and feels, especially the rainbow gradient for daily goals. Love the customisation options available too, such as hidden sidebar elements / collapsable sidebar.
However, I feel that there's a lot of UI/UX sections that can be optimised, because there's still plenty of visual clutter. (Love how Sunsama dumps most settings behind the user's profile name,)
Here are some suggestions on how the UI/UX can be cleaner.
