### 5/5 — Great tool to learn the abacus on your own

*2018-12-26, version 2.2*

After having graduated many years ago, I decided to learn to use an abacus as a precursor to delving back into math. I’ve read a couple of books on using an abacus (e.g., “The Japanese Abacus”) but never felt like I understood what they were saying.  This tutorial is well written (although several grammatical errors make it clear that it was translated) and provides a great explanation of using the abacus. I finally understand what the other books I read were trying to say but were unable to do in as clear a fashion as this tutorial. I’m also a bit leery about the two-hand method but I’m definitely going to give it a try. I only have two minor annoyances.  First, I wish the Abaculator had the option of allowing the user to manually step through the explanation with a “next step” button rather than having to pause and continue the explanation. This, however, is a minor point. Also, it would be nice to have the “Abacus Trainer” functionality (I.e, practice problems) in the app rather than being a separate app. Nevertheless, I’m happy to finally have found an abacus tutorial that I understand.

### 1/5 — No training

*2017-06-12, version 2.2*

My daughter is in level 2. I bought this app as a summer training course. We kept on reading, there is no games, that makes it really boring. Very disappointing....

### 5/5 — Would give 6 stars if possible!

*2013-07-13*

An absolutely astonishing product! Very polished and stable with no crashes to date. This is by far the best and fastest way to learn Soroban. If I had one complain it would be regarding the abundant grammatical errors present throughout the application. Having said this, I have high hopes for this application and I am sure a future update will iron out the small errors.
