Blackjack simulator for practicing card counting and testing strategies

Hi everyone,
I've been studying blackjack advantage play and card counting for a while and noticed that many training tools are either very basic or mainly designed for casual players.
So I decided to build my own blackjack training simulator.
It includes:
• Card counting training with True Count
• Full blackjack gameplay trainer
• Simulation mode for testing strategies
• Detailed statistics tracking (ROI, wager, win rate, TC filtered stats)
• Replay system with mistake analysis
The app is called "TrueCount - Blackjack Trainer" and it is currently available on the Microsoft Store.
I'm mainly looking for feedback from people who practice card counting or advantage play.
If anyone here trains with simulators I'd love to hear what features you think are most useful.
The PRO version is currently free until March 20 if anyone wants to try all the features.

One more feature I forgot to mention:
It can simulate different betting strategies and compare results over many hands. You can also set stop conditions, such as stopping at a target profit, a maximum loss, or after a certain number of hands.
It also supports TC/signal-based analysis, including threshold splits and TC buckets.

I’m interested, but the terminologies, such as ROI and TC filtered stats, are unfamiliar to me. We often use expected value (EV) and variance per 100 hands to describe the simulation results. Can you make a website for me to try out?

Thanks for the feedback.
I agree that EV and variance per 100 hands are commonly used metrics when discussing blackjack simulations. I'm currently making some adjustments to the app, and I may include EV and variance per 100 hands in a future update if everything goes smoothly.
At the moment it's a desktop application available on the Microsoft Store, so there isn't a web version yet.
Besides the basic simulation results, the app currently allows comparing different players or strategies, testing betting ramps, and applying TC filters to the results. It also includes some session-based analysis such as stop-win / stop-loss simulations and cumulative result plots across trials.
If you have experience using other blackjack simulators, I'd be very interested to hear which statistics or analysis features you find most useful.

I’ve intensively tried another blackjack simulator called blackjack-hack that was developed by Phil. The only thing I’m not very sure about this simulator is how the variance is calculated in the software part. The game of blackjack includes two parts, the main game and the insurance bet. If we neglect the insurance and play the main game only, there is an EV and a variance of the main game; however, if we play both the main game and the insurance game, there is a combined EV and a combined variance of the whole game. I want to know how you would treat this combination.

Good question.
At the moment my simulator does not include the insurance bet. Each round currently models only the main game (including doubles and splits), and the net outcome of the round is recorded directly from that.
So in the current version the EV and variance come purely from the main game. If insurance were included, then as you mentioned the total EV and variance would be the combination of the two parts (main game + insurance), either through the variance decomposition or simply by recording the combined per-round outcome in the simulation.
The main reason I haven't implemented insurance yet is that I'm building the application alone, and adding it would require quite a bit of additional work in the backend: the game flow, strategy logic, and the interaction with counting systems would all need to be extended.
Also, my understanding is that insurance is negative EV most of the time unless the count is high, so I prioritized other parts of the simulator first.
If the simulator ends up being useful to enough players, I would definitely consider adding it later. My current idea would be to include insurance as part of the strategy logic so that different insurance strategies could be tested and compared in simulations. But realistically that probably won’t happen in the short term.
