Simple Postflop Review: A Free Way Into Solvers?
Simple Postflop is a GTO solver with a rare feature at this price point: a genuinely useful free tier you can learn from before you spend a cent. On the official Simple Postflop page, the free version solves turn and river spots and ships with sample solved flops and a solved preflop tree, while the paid Standalone edition unlocks unlimited flop and preflop calculation on two PCs. Our verdict: it is the most welcoming on-ramp into solver study we have tested, and a fair-value full solver once you pay, as long as you can live with slower solves than PioSolver and a dated interface.
We have spent years watching this category, and most solvers treat the beginner as an afterthought. Simple Postflop does not. If the whole idea of a solver is still fuzzy, our primer on what a poker solver is is the right first stop, and then this review will tell you honestly where Simple Postflop earns its keep and where it shows its age.
What exactly is Simple Postflop?
Simple Postflop is a GTO postflop solver. You give it a board, the ranges for each player, the stack and pot context, and the bet sizings you want to consider, and it computes the game-theory-optimal strategy for that spot: how often to bet, which hands take which line, and how every holding responds to each action. That is the same core job the premium solvers do, and the math underneath is the math, so the answers it returns are real solved strategies rather than someone’s chart or opinion.
What sets it apart in practice is the entry point. The free tier solves turn and river spots and ships with some pre-solved flops and a preflop tree, which means you can sit down with the actual software, build a real spot, and watch a solver work before any money changes hands. That is unusual. Most tools in our best GTO solvers roundup either gate solving behind a paywall entirely or hand you a free build so crippled it teaches you nothing. Simple Postflop’s free version is constrained, but it is constrained in a way you can still learn from.
What can the free version actually do?
More than you might expect, and this is the heart of why we like it. The free tier lets you build and solve genuine turn and river spots, with the limitation being which streets you can solve rather than a locked door. You cannot run your own flop solves, but you can study the pre-solved flops it ships with: that is the trade. But within those limits you are doing the real thing, inputting ranges, choosing sizings, reading a solved output, and building the mental model of how a solver thinks.
For a beginner, that is exactly the right scope. You learn what a node is, what an equilibrium strategy looks like, why a solver mixes actions on certain hands, and how board texture moves the whole tree. None of that requires the full paid feature set, and getting it for free removes the single biggest barrier to starting. If you want a wider survey of what you can study without paying, our rundown of free poker solvers and trainers puts Simple Postflop’s free tier in context against the other no-cost options.
The honest caveat is that the free limits will eventually bind. Once you are comfortable and want to solve your own flops or run custom preflop work, you will hit the ceiling. That is by design, and it is a reasonable point to decide whether to pay.
How much does Simple Postflop cost?
Simple Postflop is positioned as a budget solver, and the pricing reflects that. The free tier is a real product rather than a teaser, and the paid Standalone edition costs $299 for unlimited flop and preflop solving on two PCs. That is under PioSOLVER Pro (EUR 450 plus tax) but about four times GTO+ (about $75), and cloud preflop solving is sold separately in “preflop points”. Here is how it breaks down as of October 2026; confirm current prices on the vendor page.
| Tier | Price (as of October 2026) | What you get |
|---|---|---|
| Free | $0 | Turn and river solving, plus some pre-solved flops and a preflop tree. A real, usable way to learn solver concepts. |
| Standalone | $299 | Unlimited flop and preflop solving on two PCs. Cloud preflop is sold separately in preflop points. |
The free tier is the standout line in that table. Unlike many free solver builds that exist only to prove the software installs, this one is a legitimate learning tool in its own right. When you need your own flop solves, the paid upgrade unlocks them along with preflop solving. At $299 it still undercuts PioSOLVER, whose heads-up preflop solver is reserved for Edge (EUR 800), but it is no longer an obvious bargain: if your own flop solves are all you need, GTO+ costs about a quarter as much.
What are the downsides?
We promised balance, so here are the real frictions, and they are genuine. First, as of 2026 Simple Postflop is slower than PioSolver on equivalent hardware. If you are running heavy sims and comparing stopwatches, you will feel the gap. For occasional study this matters less, but for high-volume work it adds up.
Second, the interface is dated and less polished. It does the job, but it looks and feels older than the slicker tools in the category, and there are rough edges where a more refined product would smooth things over. You can absolutely work in it, but you will not enjoy it the way you might a more modern interface.
Third, the community is smaller than PioSolver’s. That has a real cost: fewer shared sims, fewer forum threads when you get stuck, less of the collective knowledge that builds up around a market leader. When you hit a wall, there is simply less material out there to pull you through it. If you want to see how that established ecosystem looks on the other side, our PioSolver review covers the incumbent in detail.
The deeper limitation, and the one worth stating plainly, is shared by every tool in this class. Simple Postflop is a pure solver. It computes the optimal strategy, but it never coaches you and it never trains your decisions. You solve a spot, you get a strategy grid, and then you are on your own to decode it. Knowing the solved answer is not the same as being able to play it at the table, and a pure solver, by design, does nothing to close that gap.
How does Simple Postflop compare to DEEPFOLD?
This is the comparison we think matters most, because it is not really solver versus solver, it is solver versus solver-plus-coach. Simple Postflop solves; DEEPFOLD solves and coaches.
Here is the distinction in plain terms. Simple Postflop hands you the correct strategy for a spot and then steps back, leaving you to stare at a grid of frequencies and somehow turn it into a table-ready decision. That decoding step is the gap, and it is exactly where most study stalls. DEEPFOLD is one option built to close it: it combines an AI poker coach with its own desktop GTO solver in one product. Instead of being left alone with the output, you get your own hands analysed, with plain-language explanations of where you drifted from the solver-correct decision and drills that repeat it, until the right play stops being something you calculate and becomes something you simply do.
So the framing we keep coming back to is this: Simple Postflop solves; DEEPFOLD solves and coaches. One gives you the answer and trusts you to internalize it on your own. The other walks you through executing that answer until it becomes table instinct. If you are early enough in your journey that turning theory into reliable in-game decisions is the actual bottleneck, the coaching half is the part you cannot skip. Our DEEPFOLD review lays out exactly how that coach-plus-solver model works.
Who should use Simple Postflop?
Simple Postflop is for two kinds of player. The first is the curious beginner who wants to understand what a solver actually is before spending money, and the free tier is close to ideal for that. The second is the budget-conscious student who needs full postflop and preflop solving but cannot justify premium-solver prices, and the $299 Standalone edition serves that need, though at that price it is worth comparing against GTO+ first.
If raw solving speed, a polished interface, or a large support community is high on your list, the incumbents will suit you better, and a tool like GTO+ is another value-focused option worth weighing. And if your real problem is execution rather than computation, a pure solver of any kind will leave you with correct answers you cannot yet play, in which case the coaching side is where to start.
Our verdict
Simple Postflop earns an honest 4.1 out of 5. The free tier is a genuinely useful way into solver study, and the $299 paid upgrade delivers unlimited flop and preflop solving below PioSOLVER’s prices. We dock it for slower solves than PioSolver on equivalent hardware, a dated, less polished interface, and a paid tier that now costs about four times GTO+. Buy it for what it is, a legitimate and affordable solver with a real free on-ramp, and remember that solving is only half the work: to turn those grids into table instinct, pair it with a coach-and-solver tool like DEEPFOLD.
