This application can create the score for beginners of lyre Harp who are not familyre with score.
The problem with beginners playing songs is that they don't know which string the notes on the staff are.
For example, even if you study the position of C, you will be wondering which of C3, C4, and C5 to play.
This app does not use the staff notation, but instead uses "C4" and "G5" etc. described in Lire Harp.
Then you can easily understand which string to play.
Since the notes are displayed as those used in general score,
it is easy to read even for those who are accustomed to sheet music.
You can share the score on cloud, email etc.
You can also play the created score with the app, and can also play it as a simple instrument.
