Admittedly my iPhone 5s has a pretty small screen, so this may be tricky:
Very little of the note titles are shown when looking at a list of notes. A lot of space is taken up with the date. It’s sometimes difficult to think what the note might be about as the titles are so truncated.
A simple change that would help a bit , would be abbreviating the day of the week: Last Fri; rather than Last Friday.
And remove the time.
More radical, reduce the font size of the title and put the date under the title.
