Poker players constantly ask me what tools I recommend to improve at Pot-Limit Omaha. There’s no shortage of options — from free GTO trainers to full-featured equity solvers. But with so much noise out there, how do you know which PLO tools are actually worth your time?
In this guide, I break down the best PLO tools in 2025 — the same ones I personally use or have tested. You’ll find a mix of free and paid resources, including options for 4-card and 5-card PLO, along with tools for training, calculating equity, and even solving GTO strategies on your own terms.

MonkerSolver: Full GTO Control Without Subscriptions
While PLO Mastermind is the most complete plug-and-play solution on the market, some players prefer a more customizable approach. Whether you’re looking to avoid monthly subscription fees, want full control over your solver trees, or simply want to extend your study beyond what commercial trainers offer — MonkerSolver is a powerful alternative. It’s especially valuable for players who enjoy digging deeper into PLO GTO strategy and building their own solutions from the ground up.
MonkerSolver Paid PLO Solver
The full version of MonkerSolver unlocks advanced capabilities not found in subscription-based trainers:
- Full preflop and postflop solving
- Multi-way solving support
- ICM modeling for tournament sims
- Customizable tree construction
- Unlimited simulations
- Integrated trainer (beta)
- One-time license — no monthly fee
For serious students of the game or those building their own sim libraries, MonkerSolver offers unmatched control and long-term value.

MonkerSolver Free PLO Solver
MonkerSolver also offers a limited free PLO solver mode, primarily for solving turn and river spots. While this version can be powerful, it requires building or importing your own ranges — a process that can be tedious and error-prone without external tools.
That’s why many players pair it with a commercial trainer like PLO Mastermind, which allows users to export GTO ranges directly into MonkerSolver. This combination gives you a fast, flexible way to solve turn and river nodes using accurate GTO-based ranges.
Equity Calculators: The Missing Piece in Your PLO Study Stack
While commercial trainers and solvers are extremely powerful, they’re often missing a crucial component: an equity calculator.
Why does this matter? Because equity calculators allow you to go beyond scripted spots and analyze how ranges perform across board runouts, understand blocker dynamics, and review actual equity distributions — skills that sharpen your intuition and technical accuracy.
In PLO, many players do not understand how close equity distributions are versus those in NLHE. The best way to learn this quickly is by playing with hands and ranges in an equity calculator.
The good news? You can export GTO ranges directly from tools like MonkerSolver or PLO Mastermind into equity calculators for advanced study.
Here are two of the best options available today:
PLOCalc: The Best Paid PLO Equity Calculator on the Market
Built by the same team behind PioSolver, PLOCalc is the most powerful 4-card PLO equity calculator on the market. It performs exact enumeration (not Monte Carlo) to deliver deep, accurate equity insights for 2-player spots.
Key features:
- Import ranges from MonkerSolver or PLO Mastermind Trainer
- Postflop analysis from flop → river
- Combo-by-combo equity breakdowns
- Blocker and draw-type analysis (flush/straight/nut outs)
- Turn and river aggregation for next-street scenarios
- Advanced syntax for custom filtering
- Export tables, charts, and equity distributions
If you’re reviewing solver outputs or trying to reverse-engineer population tendencies, PLOCalc is unmatched for 4-card analysis.
Equilab – Omaha: A Solid Free PLO Equity Calculator
Equilab – Omaha remains the best free PLO equity calculator. While it lacks many pro-level features seen in PLOCalc, it still offers a ton of functionality for those looking to analyze hands or understand equity relationships.
You can:
- Run Monte Carlo simulations for hand vs range, range vs range, or multi-player scenarios
- View equity distribution graphs
- Count outs by category (flush, straight, nut, etc.)
- Input dead cards and board textures
- Evaluate 4-card PLO and PLO8 (Hi-Lo) situations
The interface is dated, but its utility is rock-solid. If you are on a budget, this powerful option can still help take your understanding of the game to the next level.
Final Thoughts
Whether you’re grinding micro-stakes or already battling mid/high-stakes, the tools above will help you make smarter decisions, sharpen your pattern recognition, and build confidence in complex PLO spots.
- Use PLO Mastermind for structured progression and a solid GTO baseline.
- Use MonkerSolver for solver-based freedom and to experiment with strategy at a deeper level.
- Use PLOCalc or Equilab to dig into equities and understand the underlying structure of the game.
Combine them consistently as a powerhouse toolset, and you’ll start seeing measurable results in your play.
