## Review summary

The app is a solid basic-strategy trainer that helps beginners learn, practice quickly, and prep for Vegas, aided by helpful stats. However, recurring UI bugs (split/drawing issues, obscured cards) and occasional incorrect or outdated strategy guidance reduce reliability. The value hinges on a subscription for pro features, and some users report pricing concerns and billing problems. Overall, it’s a strong learning tool with notable usability and accuracy issues to address.

### Pros

- Effective basic-strategy training with explanations and game-type customization.
- Speeds up practice, helps users gain confidence, and improves decision-making.
- Affordable value for training relative to real-world play and Vegas prep.
- Strong progress tracking and analytics to visualize improvement and weak hands.
- Wide range of practice options and scenarios for versatile learning.

### Cons

- Frequent bugs that block essential actions (split options sometimes greyed out or blurred, and top card obscures numbers), hindering practice accuracy.
- Strategy guidance can be inaccurate or outdated in updates (some moves are wrong, surrender rules contested).
- Pro features require a subscription, with concerns about pricing and a missing one-time purchase option.
- Billing issues and customer-support concerns (trial cancellations and unexpected charges).
