HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (3.6 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

2 of the 4 and 5 star reviews.

★★★★★ For me, this is easy to learn chess and to do chess.
★★★★★ The puzzles, the program that makes human mistakes on purpose, and adjusts itself to provide you an attainable but challenging goal, is awesome. The other chess program simply destroys me, and it never tells me a move…

初心者です

puzzleはまだ自分には難しいですが、1、2ヶ月勉強するにつれて、「このmoveは良くないよ」のコーチングメッセージが出ないまでになりました。中年からchessを始めた自分にとっては、勝つとモチベーションアップするこの上ないうれしいアプリです。

★★★★★Sep 24, 2014
Great but needs an update

This app's fantastic but crashes now with iOS 8. I hope the developer updates it soon because it really is a great tutor.

★★★★★Dec 10, 2013
パズルを目当てに購入

チェスをうまくなるためにはタクティクス(詰将棋のようなもの)をこなすのがよいと聞き、パズルが1000個あるので購入。攻守の動きを練習できてよい。インターフェイスも見やすくスムーズでとても良いと思う。ただオープニング定石は含まれていないのでtChess Proで。

★★★★★Apr 21, 2013
素晴らしい

アプリとして非常に完成されている。英語表示だけど、俺の英語力でも分かるので問題ない。 有料は他にdead spaceやFFTとか入れたけど、満足度は一番高い。 Request I'd like you to add the function to play this game with listening BGM in my ipod(≒iphone).

★★★★★Feb 25, 2013
Great way to learn and play

I love this software - for playing, for entering games I am studying, for the problems and for challenging it to get my rating against it up. I like it better on the iPad for playing but love using it on the iPhone for recording my club games. Wish list. I seem to have trouble getting a screen capture when I press two iPhone buttons. I would also like to be able to send ohm files to it and to classify the stored games or search by opening. But I have no complaints. Love it.

★★★★★Nov 29, 2012
Very good

I like this chess soft. For me, this is easy to learn chess and to do chess.
