I spent the last few months trying to build what I think is the best free blackjack tool out there

Hi, I've spent the last few months building a blackjack training app to be as good and feature-rich as I can.

I think what I like most about my app is that everything is integrated together. You can match your local casino's rules on the Learn page, see the house edge, explore strategy charts, and apply that exact setup to your practice session, or share it with someone else.

As you practice the app tracks your mistakes, estimates which ones cost you the most, and creates targeted drills to help you fix them. It also shows where your betting doesn't match your chosen bet spread.

A few highlights:

Interactive strategy charts: Shareable charts for 1–8 decks and common casino rules, with Hi-Lo deviations that update with the true count.

Bankroll Lab: Estimates risk of ruin, EV/hr, and session swings, backed by hundreds of millions of simulated hands across different table settings.

Competition for fun: Correct-play streak leaderboards, a daily shared shoe, and weekly ranked bankroll challenges with badges to earn.

Almost everything in the app is free and ad-free. There's an optional supporter tier that adds cosmetics and a few advanced training tools like being able to customize your own deviations.

So far I've gotten pretty encouraging feedback with over 3 million hands played so far, but I'm always looking to improve the app, and I'd love to know what people here think!

I believe I tried this simulator earlier this year and I just tried it again. This is the best blackjack simulator I’ve ever seen. Everything looks beautiful except one minor thing. The visual image of the discard tray needs to be redesigned, so that players see the shorter side of the card rectangle.

Great work!

Thanks a lot! Yes, I remember you gave a lot of useful feedback early on.

Thanks for the discard tray suggestion, I'll look into it!
