It is very easy to use.

First Click the Add PDF Button to add new files to the app.

And then the PDF Files list will be updated.

Then click the file to view pdf with metronome!

If the pdf is non 1-page file. The page controller will be setted.

Now you can play metronome with bpm controlled.

If the control UI is annoying to see the pdf file, you can simply drag down the control section to hide it!
