Not bad. But not perfect as the iOS version.

Bugs, glitches, crashes, etc.
Not very bad but not very good, to be honest.

Enjoy using both Mac & iOS version

Both versions of this app are enjoyable to use. Opening up the Mac version and finding all my favorite words from iOS magically present was a delightlful experience.

I appreciate that the developer keeps up to date with the latest Apple technologies and frameworks.

Word of The Day needs improvement.

Hello LookUp team.

The LookUp dictionary is good. However, there is an area where it needs improvement. This area is in the Word of the Day.

The 'Word of Day' with pictures appears in bold letters which is good, but the meaning of the word appears in very tiny letters which makes it unforcomtable to read. To read the meaning of one 'Word of the Day', you have to click on the word so as to be able to read the meaning in bolder letters.

In summary, increase the font size of the meaning of the words in the Word of the Day section. It will be more attractive to read.

There is a huge difference in font size between the 'Word of the Day' and the meaning of the word in the 'Word of the Day' section.

Kindly fix this. Thanks.
