HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (9.9 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.

Ist okay

Die App zeigt einfach und pragmatisch die Eröffnungen an. Das kompakte Design passt. Allerdings wäre eine Funktion bei den Lesezeichen sinnvoll, um Eröffnungen speichern zu können. Das suchen jedes Mal nervt. Man kann nur Spiele mit den Eröffnungen speichern. Macht tatsächlich kaum Sinn.

Gold beginning

Missing possibility to play own moves ….

Praktischer Eröffnungs-Explorer

Schön ist vor allem, dass man für jede Stellung Partien von Großmeistern findet, in denen genau diese Stellung vorkam. Außerdem kann man Stellungen als PGN exportieren und in anderen Apps anschauen. Ein schönes Feature das noch fehlt wäre eine Möglichkeit, eigene Züge zu machen und diese durch eine Engine bewerten zu lassen. außerdem wäre es schön, wenn man PGNs auch importieren könnte.

Praktikable Eröffnungsschachschule

Nach kurzer Zeit hat man das „handling“ des Schachprogramms erfasst. Durch die Vielfältigkeit des Schachprogramms bekommt man einen guten Kenntnisstand in die verschiedensten Schacheröffnungen. Sehr praktisch und hilfreich sind die beinahe unzähligen Schachpartien zu den jeweiligen Eröffnungen. Das Schachbrett ist klassisch dargestellt und von der Größe im Verhältnis zur Bildschirmgröße optimal. Kann ich nur empfehlen. Technische Probleme habe ich mit diesem Schachprogramm keine. iPad Air 3. Generation IOS 15.5

★★★★★Jun 13, 2021
In Ordnung

Von mir nur ein Stern. Mann kann hier zwar viele Eröffnungen sehen, aber danach das Spiel nicht beenden. So ist das nur nervig und entspricht nicht meinen Erwartungen. Sehr schlecht.

Not worth the money

When I buy a chess opening app I want to see the full name of the opening in the title. This is not the case on my iphone, because there is only one line for the name of the opening. And as many openings have a quite long name, the text is just cut off at the and of the line. There is no way to get the full text. Very bad!!!
