Blackjack tables are everywhere in Las Vegas, but most players sit down without ever practicing the decisions that actually matter. Small mistakes add up fast, and even “fun” sessions can get expensive if you’re guessing your way through hands.
That’s where our guide on how to play blackjack, and blackjack trainer apps come in.
Practicing before a Vegas trip helps you lock in basic strategy, understand how table rules affect the house edge, and play with confidence once real money is on the felt. Some apps focus purely on drilling correct decisions, while others add bankroll tracking, rule calculators, or card-counting practice for players looking to go deeper.
The apps below are well-suited for players heading to the best Las Vegas casinos, playing online, or sharpening fundamentals between trips.
Below are 7 of the top blackjack trainer apps available for iPhone and Android, starting with our very own all-in-one Vegas companion that pairs blackjack training with real casino tools and trip planning features.
7 Of The Best Blackjack Trainer Apps Available For Android & iPhone
Las Vegas Jaunt
Las Vegas Jaunt stands out as the best blackjack-friendly Vegas app that helps players prepare before they ever sit down at a real table. Our built-in Blackjack Trainer lets users practice correct basic-strategy decisions, including splits, doubles, and insurance, so optimal plays become automatic rather than guesswork.
The app also includes Bankroll Buddy, a session-tracking tool that records every casino visit by game, property, and trip. Players can review win/loss stats, visual performance graphs, and exportable records that are genuinely useful for tracking results and organizing information at tax time.
Beyond blackjack, Las Vegas Jaunt expands into a full Vegas companion with practical casino utilities such as a resort-fee and parking checker, multi-game bet calculator, transport cost estimator, Vegas countdown, and interactive property maps.
It also offers trip-planning features, including day-by-day itineraries, saved shows and restaurants, and access to exclusive hotel, show, attraction, and deals not typically found on other apps.
We may be biased, but Las Vegas Jaunt is the complete app for all things Blackjack, and Las Vegas!

Blackjack Trainer 101
Blackjack Trainer 101 is one of the most established and well-regarded basic-strategy trainers available on iPhone.
It’s designed for players who want to drill correct decisions until basic strategy becomes instinctive, without the distractions of simulated gambling or flashy casino visuals.
The app offers multiple training modes, including random hands, soft totals, pairs, and targeted drills, making it easy to focus on specific weak spots.
Table rules are fully customizable, such as number of decks, dealer hit or stand on soft 17, doubling options, and surrender. This means practice closely reflects real casino conditions.
Every hand delivers instant feedback, confirming whether your decision matched the optimal strategy and reinforcing the logic behind it. With its clean interface and strong emphasis on repetition and accuracy, Blackjack Trainer 101 is particularly well-suited for beginners and intermediate players preparing for live or online blackjack sessions.
The app is free to download, but if you want to remove ads, you’ll have to upgrade to the pro version for $2.99.
Blackjack 21: Strategy Trainer
Blackjack 21: Strategy Trainer strips blackjack training back to the essentials, making it ideal for players who want to focus purely on correct decision-making.
Instead of simulating a casino environment, the app removes real and virtual money entirely, keeping attention on learning proper basic strategy without card counting or unnecessary extras.
Training is built around realistic hand scenarios that reflect what you’ll actually see at a live table. You’ll work through core decisions like Hit, Stand, Split, Double, and Surrender, with immediate feedback after every choice explaining whether it matched optimal strategy and why. The included strategy chart adjusts to different house rules, so practice aligns with the game conditions you plan to play. This straightforward, feedback-driven approach makes the app particularly effective for newer players who want to build confidence, tighten their fundamentals, and avoid expensive errors once real money is on the line.
However, if you want to make use of all the pro features, you’ll have to pay anywhere between $7.99 a month, $23.99 if you pay for the year, or $49.99 for a lifetime subscription.
Blackjack Trainer: All‑in‑One
Blackjack Trainer: All‑in‑One takes a broader, more analytical approach to learning blackjack by combining training, math, and theory in one place. Rather than focusing on repetition alone, it’s built for players who want to understand the mechanics behind optimal decisions and how table rules influence long-term results.
The app’s Basic Strategy Trainer includes structured guides, strategy charts, and quick drills designed to reinforce correct play across all hand types. What sets it apart is the House Edge Calculator, which lets users modify rules like deck count, dealer behavior, and surrender availability to see exactly how small changes affect the casino’s edge. For players ready to go deeper, the card-counting module introduces shoe tracking and explains how consistent counting can turn a standard blackjack game into a potential advantage. With clean HD graphics, offline support, and a comprehensive blackjack guide covering both live and online play, it’s a well-rounded option for players moving from fundamentals toward more advanced strategy concepts.
The price to use the app’s full features ranges from $3.99 to $4.99.
Blackjack Ace – Basic Strategy
Blackjack Ace – Basic Strategy is a free to download app built for players who want to dial in correct blackjack decisions under real-world rules.
It supports both American and European rules and focuses on basic strategy rather than simulated gambling. The app lets you customize table conditions, everything from the number of decks, dealer hit/stand rules, surrender options, and more. Then it automatically generates a strategy chart tailored to that exact game.
In practice mode, you’re dealt one hand at a time with instant feedback explaining the correct move and the strategy principle behind it. Play Mode runs full blackjack sessions so you can see whether your decision-making holds up over time, similar to a live casino. Detailed accuracy tracking highlights where you’re leaking EV, making it easy to spot weak situations and focus future practice where it matters most.
One thing to note is that this app is avaliable on Android only.
Blackjack Strategy Trainer
Blackjack Strategy Trainer (not to be confused with Blackjack Strategy: 21) is another lightweight Android app. It’s free to download and is designed to help players improve their blackjack decisions by learning directly through play.
Rather than separating training and gameplay, it corrects mistakes in real time, making it easy to tighten up your strategy without breaking your rhythm. The app supports fully customizable table rules, automatically adjusting basic strategy and providing a tailored in-app strategy card to match your chosen conditions.
In normal game mode, it plays like a standard blackjack session but flags any move that deviates from basic strategy so you can fix errors immediately. Quick Trainer Mode skips full hands and deals only starting hands with the dealer’s up-card, making it ideal for fast memorization and repetition. Free to use and ad-supported, it’s a solid entry-level option for Android players who want to sharpen their fundamentals before heading to a real casino.
Steve’s Blackjack Trainer Pro
Steve’s Blackjack Trainer Pro is a more advanced blackjack trainer aimed at players who want to move beyond memorizing basic strategy and start understanding long-term edge and discipline. It blends structured training with deeper analysis tools, making it a strong step-up option for serious learners.
The app includes interactive basic-strategy training with instant feedback, alongside card-counting practice modes that help users learn how shoe composition affects decision-making. Detailed hand histories, accuracy tracking, and session stats make it easy to review mistakes and measure improvement over time. Multiple training modes allow players to isolate specific scenarios or run longer simulated sessions to test consistency under realistic conditions. With a clean interface and a focus on data-driven improvement rather than gambling simulation, Steve’s Blackjack Trainer Pro is well-suited for players who already know the basics and want to sharpen their edge before playing in real casinos.
This app is available on both iPhone and Android, and costs $2.99 to upgrade to VIP Premium.
