User Reviews

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 However, recurring UI bugs (split/drawing issues, obscured cards) and occasional incorrect or outdated strategy guidance reduce reliability.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Strategy guidance can be inaccurate or outdated in updates (some moves are wrong, surrender rules contested).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).

Recent reviews

Could use more features but is very strong at what it does.

Haven’t played BJ in a while. BJT is an excellent way of refreshing my skills

I did a seven day trial, put a reminder in my calendar to cancel and they STILL billed my card for a one year subscription. Totally outrageous and borderline criminal. I have reached out to them, we will see if they do the right thing or not.
