It looks quite all right.

The abacus which created by chinese. The earliest known written documentation of the Chinese abacus dates to the 2nd century BC. In the famous long scroll Along the River During the Qingming Festival painted by Zhang Zeduan (1085–1145 AD) during the Song Dynasty (960–1297 AD), a suanpan is clearly seen lying beside an account book and doctor's prescriptions on the counter of an apothecary's. The abacus, also called a counting frame, is a calculating tool used primarily in parts of Asia for performing arithmetic processes. Today, abacuses are often constructed as a bamboo frame with beads sliding on wires, but originally they were beans or stones moved in grooves in sand or on tablets of wood, stone, or metal. The abacus was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Africa, and elsewhere.

Okay, but nor responsive enough

I've tried all the abacus Programs I could find on iTunes and this is one of two that I keep on my iPhone. I like the decimal point option, but that is the only reason I keep it around. It is not responsive and I have to keep swiping and pressing at beads to get them to move. It is too slow to use for basic calculations.
