This is a personalized app designed for guitar players. Since the age of guitar lovers is widely distributed, Neumorphism style is adopted to avoid the situation that some seniors have difficulty in understanding the flat interface because it is between Skeuomorph and flat design.
 

The functions include basic sheet music, tools and so on. The users can join the guitarist society just like the App name "Guitar Club", they can post related contents and interact with other guitar lovers. In addition, the users will get music recommendations according to the type of songs they play in the App.
