FreeBetRange is a powerful tool for mastering preflop that works right in your browser. It includes a Range Builder, Viewer, and Trainer with two study modes.
You can:
- build your own ranges from scratch,
- use our own GTO Library with 100,000+ preflop ranges,
- or import ranges from solvers and other tools (PioSolver, HRC, etc.).
🧠 CORE FEATURES (more information in the user manual)
You can practice both GTO ranges and your own custom ranges using two efficient learning modes:
Classic mode:
In every "hand," you'll be dealt 2 cards, and you have to make a decision.

Mobile:
Range mode:
You'll try to replicate the original range and check the accuracy of your answer.

Review detailed training stats, including a heatmap of all played hands for each range.

A fast, intuitive way to navigate through your preflop strategy. Instantly visualize every spot with a clean, customizable layout.

Mobile:
Also, a multi-range mode allows you to view and compare multiple ranges at once.

Full control over your strategy β create your own trees, edit solver outputs, or import ranges from other tools.

A vast collection of ready-to-use preflop strategies for all major poker formats: Cash games, MTTs, Spin&Go, and Mystery Battle Royales tournaments (MBR).

Each solution includes a full preflop tree: for every possible spot, the app shows a GTO-range for how all hands should be played.
You can add any strategy to your account and then use it in the Editor, Viewer, or Trainer.
Solutions are grouped by type:
- GTO β original solver ranges (for deep study)
- Simplified GTO β same strategy but weights rounded to 0/25/50/75/100% for easier memorisation and practice.
Freebetrange is fully optimized for mobile devices. You can install it as a PWA app and use it as any other app on your phone.

Any feedback, comments, and suggestions are welcome here in this thread, or in our Discord community.
Good luck at the tables!

Ive tried to import 3 Simple Preflop Ranges into 1 Matrix, but im getting frequency Errors when trying to add 3rd Range.
I could only manage to combine 2 Ranges into 1 Matrix so far, is combining more Ranges via Import Feature possible?

Hello! You can import 3 ranges in 1 matrix as well, but for that we recommend turning off the "Round frequencies" setting.
Nice tool β do you have plans for MTT-specific ranges with ICM considerations, or is this primarily cash game focused?
Weβve just added a new MDA (Mass Data Analysis) section to Freebetrange.
Itβs based on 300M+ real cash game hands and uses a statistical reconstruction pipeline to estimate full preflop ranges (not just raw showdown data, which is biased). The result is stable, realistic population ranges for different player archetypes (regs, fish).
You can filter by stakes, table size, ante, room pool, and player type, then navigate the full preflop tree spot by spot.
Main value: instead of guessing or relying only on GTO, you can see how the pool actually plays and build exploit strategies on top of that.
