The short answer

PokerSnowie is an AI poker coach: a neural network that taught itself No-Limit Hold’em through self-play, launched in 2013, sold today as one $29.90/month subscription for Windows, Mac and iPhone. You play hands against it, import real sessions, and it flags your mistakes. GTO Preflop is a mobile preflop solver library and trainer: 503 solved scenarios covering cash, MTT and Spin & Go, with EV-graded drilling, for $119.99 a year.

The split comes down to what you trust and where you study. Snowie’s advice is an estimate from a network trained over a decade ago, and its mobile apps have been frozen since 2018 and 2022. GTO Preflop’s advice is computed solver output you can audit, in an app that shipped its current builds in May 2026. If you want a sparring partner that plays whole hands with you on a desktop, Snowie still does something we don’t. If you want your preflop game built on numbers instead of intuition, that’s us.

Note:

Full disclosure: GTO Preflop is our app. Every PokerSnowie price and feature claim below was checked against PokerSnowie’s own website, manual and store listings on September 2, 2026, and we’ve been specific about the categories Snowie wins.

Who should pick which

Pick PokerSnowie if this sounds like you:

  • You want to play full practice hands against a tough opponent and get told, street by street, where you went wrong. GTO Preflop never deals a flop; Snowie’s whole product lives in that loop.
  • You play 10-handed live full ring. Snowie’s preflop advisor covers 10-max tables; our library stops at 8-handed.
  • You study on a Windows or Mac desktop and don’t care that the phone apps are museum pieces.

Pick GTO Preflop if this is closer:

  • You want advice you can check. Solver output comes with EVs attached to every action; a neural network’s recommendation comes with nothing behind it but the network.
  • You play tournaments or Spins. Snowie’s own blog says it was trained on cash hands and isn’t optimized for tournaments. Our library solves MTT structures with antes at 14 stack depths and Spin & Go from 1.5BB up.
  • You study on a phone. Our current iOS and Android builds shipped in May 2026; Snowie’s main iOS app has been sitting at version 1.2.3 since July 2018.
  • You’d rather pay $119.99 a year than $29.90 a month.

A concrete version: a home-game player who wants to stop overvaluing top pair and enjoys playing against a bot should take Snowie’s 10-day trial and will probably like it. A player who opens too wide from the hijack, flats junk in the small blind and studies on the train should fix the preflop layer first, with numbers, for a third of the price.

An approximation or a calculation?

This is the real difference, and it’s worth two minutes because it decides what your study hours are worth.

PokerSnowie is a neural network. It learned No-Limit Hold’em by playing what its marketing calls trillions of hands against itself, and when you ask it a question, it estimates the answer from the patterns it absorbed. That was a genuine breakthrough in 2013, before PioSolver existed. But an estimate is all it is. Snowie’s advice comes from a fixed architecture: its manual documents four bet sizes to choose from (1/4 pot, 1/2 pot, pot and 2x pot), and its preflop advice table shows each of the 169 hands as a color: green for raise, yellow for call, white for fold, with an optional raise percentage.

A solver doesn’t estimate. It iterates a specific spot until neither player can gain by deviating, then hands you the strategy with the EV of every action attached. You can audit it. When two tools disagree, the solver can show you its math; the network can only repeat itself.

Here’s what that looks like in practice. We opened one node of the database that ships inside GTO Preflop, the under-the-gun first-in decision at 8-max, 100BB, on a raked cash table, and measured every hand in it:

Bar chart of UTG first-in raise frequencies from GTO Preflop’s solve database: A5s and KTs raise 100% earning +0.064BB, thirteen hands from K5s at 98.6% down to T9s at 4.9% are mixed with raise EVs within 0.003BB of zero, and 87s and 22 are folds that would lose 0.045BB and 0.075BB

Twenty-nine hands raise every time. Fourteen more are mixed, and every one of them has a raise EV within 0.003BB of zero: 77 opens 52.4% of the time because raising and folding are worth almost exactly the same, 65s opens 45.1%, T9s just 4.9%. Meanwhile the clear decisions carry real money: folding A5s here gives up 0.064BB every single time, and raising 22 costs 0.075BB. The EV column is the part that teaches. It tells you which disagreements between you and the chart are punts and which are rounding errors, so you know where the study time should go; our guide to memorizing preflop ranges is built on exactly that principle. An advice grid without auditable EVs behind it can tell you what it would do. It can’t prove how much anything matters, or that it’s right.

For the theory those files encode, our starting hands chart guide walks the opening ranges seat by seat.

What about tournaments?

Snowie answers this one for us. Its own blog, explaining tournament hand imports, says PokerSnowie “has been designed and trained with cash game hands in mind” and “is not optimized for tournaments, since it does not take into consideration the prize distribution.” That’s an honest admission, and it has real consequences for anyone whose poker happens in MTTs, sit & gos or Spins.

Ante structures change correct preflop play beyond what a cash engine can extrapolate. One measured example from our library: at 100BB in an MTT structure with a 12.5% ante, the small blind’s first-in strategy is to limp 86% of hands, raise 5.6% and fold just 8.4%. On the raked 100BB cash table, the same seat limps just 2.3% and raises everything else it plays. Same depth, same position, opposite strategy, purely because antes and rake changed the price of playing. A network trained on cash hands has never seen the format where limping is the backbone of the strategy. Our blind vs blind guide covers those numbers in depth.

Below 10BB it gets starker: in our MTT files the only solved opening raise at 3BB to 8BB is all-in, the jam/fold territory that decides every tournament run. GTO Preflop covers MTT ChipEV at 14 depths from 3BB to 100BB across 2, 4, 6 and 8-handed tables, plus Spin & Go at 17 equal-stack depths from 1.5BB to 34BB and 418 asymmetrical stack spots. Our MTT stack size guide shows how the ranges shift depth by depth. None of that exists anywhere in Snowie’s product line.

What do they cost in 2026?

All PokerSnowie prices below come from its own pricing page, checked September 2, 2026.

Product Plan Price
PokerSnowie Monthly $29.90/mo
PokerSnowie Annual (first year) $199.90 ($16.66/mo marketed)
GTO Preflop Pro monthly $19.99/mo
GTO Preflop Pro annual $119.99/yr

Snowie simplified its pricing in recent years: the old Intermediate and Pro tiers are gone, and one subscription now covers everything on Windows, Mac and iPhone. Two gotchas hide in the fine print. The advertised 44% annual saving “applies to the first purchase only,” in the pricing page’s own words, and “all future renewals will be billed at the standard rate.” And all prices exclude VAT, which EU players pay on top. There’s a genuine 10-day free trial, which we’ll credit in a moment, and the license is personal-use only.

GTO Preflop is free to download. Pro costs $19.99 a month or $119.99 a year on the standard plan, with a $7.99 weekly option for short study bursts. We run pricing experiments, so store listings sometimes show other price points; $119.99 is the standard annual price and exact prices vary a little by region.

So year one runs $199.90 against $119.99, and after the discount expires the gap widens. For $80 less than Snowie’s discounted first year, you get the entire solved preflop layer for three formats instead of one engine’s estimates. If the tool you’re actually cross-shopping is bigger-name solver software, our GTO Wizard comparison runs this same exercise at the premium end of the market.

Which is better on mobile?

This one isn’t close, and the dates tell the story better than we can.

Timeline of last shipped updates: PokerSnowie’s main iOS app July 2018, PokerSnowie 4 desktop and the final company blog post May 2022, the Snowie Preflop iOS app October 2022, its Android app May 2023, and GTO Preflop’s current iOS and Android builds May 2026

PokerSnowie’s own downloads page lists three platforms: Windows, Mac (macOS 10.12 or later) and an iPhone app. There is no Android version of the main product at all. That iPhone app sits at version 1.2.3, last updated July 27, 2018, rated 2.4 stars across 16 US ratings, and it requires the subscription to use. The separate PokerSnowie Preflop app, a free range viewer, was rebuilt in October 2022 and hasn’t been touched since; its Android sibling holds a 1.9-star rating across 158 reviews and last shipped in May 2023. The company blog’s most recent post, announcing that preflop app, is dated May 28, 2022. Even the online manual opens with a notice that some of its contents are outdated, and that the Mac version still lacks the Hands Import and Hand Range features.

GTO Preflop shipped iOS version 3.0.30 on May 26, 2026 and its current Android build on May 22, 2026. It holds 4.8 stars across 240 US App Store ratings and 4.6 across 3,250 Google Play reviews on 100K+ downloads, and it runs natively on iPhone and iPad (iOS 15.6+), Android and Apple Silicon Macs. Fresh builds aren’t vanity. They tell you whose roadmap your subscription is funding, and whether the bug you hit next month will ever be fixed. Working mobile study tools are rarer than they should be in poker, as our Equilab alternatives rundown found across the whole category, and an eight-year-old binary is not one.

One small data point from our side of the counter: we run Apple Search Ads, and App Store searches for PokerSnowie’s brand name produced attributed GTO Preflop installs in the most recent 30-day window we measured. Attribution captures a floor, not a total, but some of Snowie’s mobile-minded shoppers are already reaching the same conclusion this section did.

Where PokerSnowie genuinely wins

Credit where due: these categories are Snowie’s, and if one of them is why you’re shopping, buy accordingly.

  • It plays whole hands with you. Practice sessions against the AI with live feedback, street by street. GTO Preflop has no postflop content and never will pretend otherwise.
  • It analyzes your real hands. Import sessions from online rooms and get an error report on your actual play. We don’t do hand import.
  • Full-ring coverage. Snowie’s preflop advisor handles 10-handed tables; our library stops at 8-max.
  • Pedigree. Snowie has been shaping how amateurs think about balance since 2013, its site claims over 220,000 players, and heads-up legend Dan “Jungleman” Cates lends it a testimonial. That history is real, and so is the effect it had on the games.
  • A real free trial. Ten days, full product. That’s a fair way to sell software and more than many rivals offer.

What we’d push back on is the price of that history. $29.90 a month in 2026 buys the same architecture that was cutting-edge when solvers didn’t exist: four bet sizes, cash-trained instincts, and advice you take on faith. The market moved to computed, auditable output years ago, at every price point including free.

Switching from PokerSnowie to GTO Preflop

What you keep: GTO-based preflop advice for every seat, now with exact frequencies and EV numbers instead of color codes; a training loop that grades your decisions; mobile access that actually works.

What you lose: everything postflop. The practice-hand sessions, the hand import, the error rate graphs. If playing against the AI is the part of Snowie you love, keep the subscription for that and treat us as the preflop upgrade; the overlap costs $119.99 a year.

Time to set up: minutes. Install, pick your format and depth, and start answering hands. Every answer comes back with the EV cost attached, and an ELO rating calibrates itself over your first sessions. One honest limit: the trainer deals cash spots across the full 50BB to 200BB range and tournament spots from 3BB to 12BB, the jam/fold depths that decide tournaments; Spin & Go ranges and deeper MTT stacks are reading material in the range viewer, not dealable drills. Most switchers still find out fast that one seat’s opening range was built on decade-old instincts. That first uncomfortable number is the product working.

Tip:

Test the two engines against each other: get the app, pull up a spot you think you know, and compare what Snowie tells you with what the solved chart and its EV numbers say. Where they disagree, only one of them can show you why.

PokerSnowie vs GTO Preflop: FAQ

Is PokerSnowie a solver?

No. PokerSnowie is a neural network that learned poker through self-play and estimates decisions from learned patterns. A solver computes the equilibrium for a specific spot and attaches an EV to every action, which means its output can be checked. GTO Preflop’s charts are solver output; Snowie’s advice is the network’s opinion.

How much does PokerSnowie cost in 2026?

One subscription at $29.90 a month, or $199.90 for the first year (marketed as $16.66/month, a 44% saving that its pricing page says applies to the first purchase only, with renewals at the standard rate). Prices exclude VAT for EU customers. A 10-day free trial is available, and the old Intermediate and Pro tiers no longer exist.

Is PokerSnowie still updated?

The desktop product is actively sold, and PokerSnowie 4 for Windows and Mac arrived around May 2022. Visible development since then is hard to find: the main iOS app was last updated in July 2018, the Preflop apps in October 2022 (iOS) and May 2023 (Android), and the company blog’s newest post is from May 2022. The online manual itself warns that parts of it are outdated.

Does PokerSnowie work on Android?

The main PokerSnowie product doesn’t exist on Android; its downloads page offers Windows, Mac and iPhone. The only Snowie app on Google Play is the free PokerSnowie Preflop range viewer, rated 1.9 stars across 158 reviews and last updated in May 2023. GTO Preflop ships current native apps on both iOS and Android.

Is PokerSnowie good for preflop study?

It’s a starting point. The preflop advice table shows a color-coded action for all 169 hands with optional raise percentages, and the rebuilt preflop app covers 6 and 10-handed tables at 50, 100 and 200BB. What it lacks is the layer that makes preflop study stick: auditable EV numbers per action, tournament and Spin & Go structures, and a maintained trainer to drill against. Its engine is also cash-trained, by its own description, so tournament preflop advice is outside what it was built for.

Is GTO Preflop a good PokerSnowie alternative?

For preflop, yes, and we’d argue it’s the upgrade: solved ranges instead of estimates, EV-graded drilling on every decision, cash, MTT and Spin & Go coverage in one $119.99/year subscription, on apps updated in 2026. It is not a full Snowie replacement for postflop practice hands or hand-history analysis; nothing in our app deals a flop.
