I love this app! Its fast, beautiful, and comprehensive. Makes it very easy to practice and learn all the most common (and rare) openings. The author is active on improvements, and takes user recommendations to heart. HIGHLY RECOMMENDED!!!" -- by ECHOOooo


"Great opening tool - *****

There are very few apps that I will take the time to review. However, this is one app that I use every day. It sharpens my opening knowledge Nd would be worth far more than the price at which I purchased it. Kudos."

Pros and cons of Chess Openings Pro app for iPhone and iPad

Chess Openings Pro app good for

Awesome App. Nice would be a Reset button to begin a new opening analysis.
This Opening software really helps to better understand the dschungel of opportunities coming up during your first draws ...
Hi , I love your app. I use it all the time. Would you consider adding a note field so that users can add their own notes about the opening? That way I could remind myself about strategies or just basic opening variation goals or plans. Love the app but it would sure be more useful.
This is an amazing application for many reasons ... Properly learn to use it and you will have one of the best Chess tutor programs ever. Truly amazing !
Great program - just what Ive been waiting for for iOS. Start moving pieces and it tells you what opening youre in. Very handy.
I never buy apps, but am glad to have been tempted by this one. Remarkable!

Some bad moments

What a bunch of amateurs. Is it really a big deal? Yes. Am I impressed with this app? no.
Most lines go just 5-6 moves deep, and there are no full games. It is basically useless for anyone rated over 1400.
The program doesnt allow you to begin an opening and thereafter make your own moves. I would prefer that I be able to play my own game after the opening as if I were playing a human.
I had a difficult time just figuring out how to study the openings - much less studying them. This app makes it manageable.
Great app and easy to use. Sometime I when I pick the right choice it says my answer is wrong and the correct choice is the one I picked. Please fix. Also I dont show the name of the openings after awhile.
I paid money for this app and discovered this. This app does not support Horizontal view. It only supports Vertical view. iPad apps should support both.
