## What is YUBI Number?

YUBI Number is a piano fingering app for all piano beginners. 

The app is divided into 2 steps. 

In STEP1, you will learn the finger numbers with your finger movement. As you practice with this app, you will get used to fingering while playing. 

In STEP2, you will practice playing the keyboard followed by correct fingering. You can also learn the notes and their positions on the keyboard. You will be required to play the notes as per the correct fingering displayed on the screen. 

Both sections have3 levels of difficulty (easy, normal, hard) based on the speed of the indication displayed on the screen. Easy mode is already good enough practice to do. 

You will see if you play correctly or not by hearing. Please make sure to turn off the silent mode while playing the app. As for the hard mode, you will hear the sounds only when you play correctly. 

This app enables you to practice fingering where you don’t have a piano or keyboard.

### 1/5 — Buggy

*2022-09-26, version 1.0*

The fingering on circles works, but the piano keys and finger numbers don’t show up in the piano keys section, it’s just blank.
This app is very buggy and doesn’t work properly on my updated iPad.
