"Brilliant - *****

Thank you for putting together a BEAUTIFUL opening app. I can't image anything better." -- by FraudAlert

"Excellent...NONE BETTER - *****

I love this app! It's 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."

"Awesome - *****

Easy to use. Easy to follow. Great for those indisposed multitasking opportunities... Strong work fellas!"

Customer Reviews

Exactly what I wanted

I was looking for a database of openings that I could easily study in spare moments. I have some books which talk about opening theory and variations, these are interesting but I am not yet at that level. The most useful things I have found are videos from the Saint Louis Chess Club and this app. Quiz mode is fabulous, and you can quickly flip from the quiz to full openings. The only criticism I have is that the search function is not robust (if I type "queen Indian" it will not find "Queen's Indian"). But it's still easily worth the price!

Even Great for Beginners

I'm far from at the point where I need to memorize even a handful of openings, and even I can benefit from this amazing tool. It's perfect for analysis, and for getting the hang of even the first three moves to see where you can develop from there. I'm sure as I progress, this will become ever more useful, but I'm already getting a lot out of Openings.

If I had one gripe about this app, it's missing support for landscape mode. Not only would that make it less annoying, it would allow the developer to use the screen more efficiently.

Chess player

The data base seems to be as good as any internet database I have used.

I mainly purchased the app for the quiz mode, which I like but is only good.

Sometimes it says your close, when you are correct. Sometimes it say good choice, when you are wrong.

Also, it would be awesome if you could see the rest of the opening you are working with, either with a continue button or way to start the engine.

A good app tho.

New update not as good.
Fonts too small
No quiz score or progress (difficulty bar gone).
Pieces don't fly into position, it was good to see the opening develop.

I would also prefer the old version.

Another update!
Getting better, but it sometimes tells you your right when your wrong, or close when you selected the correct answer.

Fix that, and the quiz mode would be awesome.

Great app!!
