User Reviews

Users praise the app for its fast, visual openings interface and access to grandmaster games for study, plus clear move-strength insights and an affordable workflow. However, multiple reviews cite a lack of onboarding, unclear metrics, and confusing usability, along with bugs that affect game positions and lists. Overall, it’s a strong, value-conscious openings study tool that needs better guidance and bug fixes to fully realize its potential.

Pros

Fast, informative openings interface with instant visibility of winning moves and easy replay of grandmaster games.
Effective study workflow: practice variations and gauge the relative strength of moves within an opening.
Rich collection of master games tied to openings provides practical, real-game examples to study.
Affordable and simple to use, offering good value for an opening-focused study tool.

Cons

Poor onboarding and guidance: no clear instructions and unclear metrics (percentages), making it hard for beginners.
Bugs affecting reliability: games can appear in the wrong position and the game lists can freeze or stop working.
Confusing, hard-to-follow interface without sufficient help or tutorials.

Recent reviews

Awesome interface! You can instantly see which opening moves result in game wins, and conveniently practice the numerous variations. One of my favorite features is that you can see and replay games by chess masters using each opening. I’ve been playing chess for decades, and this app helped me “get” the openings in a few weeks better than any other training or coaching over the years! Well done to the developers! Hope they keep the app going.
