AbacusPro

 
 

Abacuses from three different time periods are included. The modern Japanese “Soroban”, the traditional Chinese “Suanpan” and the next generation suanpan.

 

A great addition to your collection of Educational, Utility and Novelty apps

The soroban is my flagship abacus with visual features to aid the novice or casual user. Choose between a 15 digit numeric display or individual number boxes.


Set the desired decimal point location for those calculations requiring decimal math. Great for classroom instructional use.

A fourth and treasured abacus is included. It is the rare and highly sought after Lee Kai-chen ‘Improved’ Abacus, circa 1950.


This distinctive calculating device is 3 abacuses in 1. Two 9 rod sorobans sit above a traditional suanpan. The suanpan includes a moveable vernier with decimal point and ‘thousands’ commas. Proficient users can do complex calculations easily with this amazing device.

AbacusPro has ‘extras’ such as numeric displays and reset buttons for clearing the beads to zero. Rapid bead movement is guaranteed to please even the most accomplished users.


Numeric displays were enhanced to aid those with impaired vision.

While AbacusPro will not instruct in the use of this timeless calculator, it is an invaluable instructional tool.


I provide several web and YouTube links that will pique your interest. With practice you can become proficient at math and mental calculations.

Make great use of this ancient wonder on your high tech device.
