Tactics for Android

First a "tactic" in this app is 1 MOVE, so 1 "puzzle" could count for as many as 5 "tactics" so you may not get 100 puzzles for 99¢, second, not all are tactics, some puzzles are just for the best move, which can be confusing if you're looking for a tactic.

There are no instructions on how to use this app.

At a certain point the app will crash EVERYTIME you key in a move.

This is the most confusing, least functional chess tactics program I've ever seen for iOS; there's no reason in the world this software should've been released in this lousy condition. It's embarrassing how badly ChessBase is adapting to the new world of tablet computing and mobile apps.

Not sure what they're thinking putting this on such a respected brand. Input is clunky and it sometimes takes several tries for a move to register. Some of the variations seem a bit odd too. It may have just been the frustration building up, but it seemed to ask you to perform menial tasks such as find the pin when there was a mate on the board. Tactics are a decent training tool IF you can go back and figure out why something was played. Otherwise it is an exercise in futility. A tactics trainer should let you play around with the solution so you understand what just happened. This doesn't include that, it doesn't give variations when you've solved the problem, and you can't even stop and look at the board when you've found the solution. It just takes you to the next task without giving you time to learn from the puzzle. The result is a waste of time.
