Freebetrange: #1 App for Custom and GTO Preflop Ranges
If you want to become a winning poker player, preflop is where it all begins. Every hand starts preflop, and your decisions here shape everything that comes after. A strong preflop strategy helps you:
- Avoid common beginner mistakes
- Save chips in losing spots
- Win more when you have the edge
- Feel more confident going into the flop, turn, and river
Many micro-, low- and mid-stakes players struggle here because they don’t have a structured system.
That’s exactly where Freebetrange can help.
🔍 What Is Freebetrange?
Freebetrange is a modern browser-based poker app that helps you study, build, and memorize preflop ranges. You don’t need to download anything — just open the website and you’re ready to go. It works perfectly on both desktop and mobile.
The app is designed for all skill levels, but it’s especially helpful for players who are serious about improving and want a tool that’s both powerful and easy to use.
Freebetrange is divided into four main sections: Editor, Viewer, Trainer, and the GTO Library. Let’s take a closer look at each one.
🛠️ Editor – Build Your Own Preflop Ranges
The Range Editor is where you can create, import, or customize your own preflop charts. You can build ranges for any spot — open-raises, 3-bets, cold calls, and so on. You can assign different colors and frequencies to any hand.
This is great if:
- You want to build a personal strategy for a specific game format;
- You’re working on your leaks and want to experiment with different preflop ideas;
- You're just started with ranges and want to practise drawing them.
Building your own ranges is also a great exercise to better understand how preflop ranges are structured and why certain hands appear in specific spots. This kind of hands-on work helps reinforce good habits and deepen your overall strategy knowledge.
The interface is very clean and beginner-friendly.
👁️ Viewer – Study and Navigate Your Charts
The Range Viewer is useful to quickly navigate and study your custom or GTO strategies for various game formats. You can easily switch between positions, stack depths, or specific preflop scenarios like vs open, vs 3-bet, or BB defense.
In some poker sites where using preflop charts is allowed, you can also consider using the Viewer to check your charts while playing. But be careful — most sites prohibit the use of third-party tools during play, so always follow the platform’s policy.
Freebetrange Viewer is a great tool to explore your preflop strategy in a clear, visual way.
🎯 Trainer – Practice Your Preflop Decisions
This is one of the most useful tools in the app. The Preflop Trainer helps you memorize and internalize preflop decisions with two efficient learning modes:
- Classic mode – Make decisions with specific hands, just like you would at a real table
- Range mode – Draw full ranges for given spots and check the accuracy of your answers
You’ll get instant feedback and accuracy stats, so you can quickly identify leaks and improve.
The Freebetrange Preflop Trainer is a fast and intuitive way to practice. It’s one of the best poker trainers on the market — a perfect tool to sharpen your decisions and turn GTO theory into muscle memory.
📚 GTO Library – Pre-Made Solver-Based Ranges
The GTO Library gives you access to ready-to-use preflop strategies based on real solver outputs. This is great if you don’t have time (or budget) to run your own sims.
You can:
- Choose from different formats (Cash, Spins, MTTs)
- Study both full GTO and Simplified GTO versions
- Load the ranges into your account and train them instantly
This makes Freebetrange not only a personal range builder, but also a GTO learning platform.
