This "Handy Abacus" is an application based on a Japanese abacus. This handy 5 rows and 5 columns structure gives better usability and also demonstrates closer to a real bead movement. It can be used for every day grocery shopping or for beginners who just start learning or keep practicing whenever they have free time.

It is designed to

1) display / undisplay numeric value of bead position
2) adjust a decimal point by moving a black point on the center bar.
3) add / remove a gravity effect on beads
4) quick reset beads by pressing a button
5) reset upper or lower beads by moving a finger along with beads closer to the center bar
