User Reviews

Overall, users praise Chess Opening Blunders for its strong, varied puzzles that sharpen tactical play and its replay/analysis features, plus real-player annotated lines and a focus on reducing opening blunders. Many reviewers find it unique and preferable to other puzzle apps, and several report noticeable rating improvements. However, several consistent complaints emerge: the difficulty is uneven, with some puzzles far too hard for average players and others too easy; the opening-theory content is deeper than the branding; the interface can feel clunky; and some puzzles lack explanations. Users want more guidance and more content.

Replayable games with built-in analysis and multiple annotated lines by real players.
Unique app for opening/blunder training; praised as better than some alternatives.
Helps reduce opening blunders and improve opening play.

Cons

Puzzles can be too hard or too easy; difficulty is inconsistent and not suited for all players.
Opening theory depth is excessive; puzzles start late in the game, not aligned with the opening-blunders focus.
Interface feels clunky or not polished.
Some puzzles lack explanations or hints, leaving players guessing.
Difficulty ratings are inconsistent (some high-rated puzzles are very hard, others easy).
