The short answer

Both are real products from people who understand tournament poker. DTO Poker, built by high-stakes pro Dominik Nitsche, is at heart a postflop MTT drilling tool: you rehearse presolved tournament spots against simplified GTO strategies, from $9.99 a month. GTO Preflop is a mobile preflop solver library and trainer: every position, three formats, with EV-loss grading on every decision, for $119.99 a year.

The split is simple. If your study time goes into rehearsing postflop tournament spots and you want a famous pro’s simplified strategies to copy, DTO does that and we don’t. If preflop is where your money leaks, and you want the full solved layer for cash, MTT and Spin & Go in one app that’s still being updated, that’s the job GTO Preflop was built for.

Note:

Full disclosure: GTO Preflop is our app. Every DTO price and feature claim below was checked against DTO’s own pricing pages and store listings on September 1, 2026, and we’ve been specific about the categories DTO wins.

Who should pick which

Pick DTO Poker if this sounds like you:

  • You want to drill postflop tournament spots, not just preflop. GTO Preflop stops at the flop; DTO’s whole product lives past it.
  • You like the philosophy of simplified strategies (fewer bet sizes, cleaner decisions) endorsed by one of the most technically respected tournament pros alive.
  • Your budget says $9.99 a month and you accept pass/fail grading at that price.

Pick GTO Preflop if this is closer:

  • Preflop is your leak. You make a preflop decision every single hand, and Upswing Poker calls playing too many hands before the flop the number one mistake among losing players.
  • You play more than one format. One GTO Preflop subscription covers cash, MTT ChipEV and Spin & Go ranges. DTO sells tournament and cash training as separate subscriptions, with its deep preflop packs priced on top.
  • You want EV numbers on every graded decision without climbing a tier ladder to get them.
  • You study on a phone and care whether the app in your pocket is still being maintained.

A concrete version: a $22 ABI grinder who reviews final tables on a laptop and wants to rehearse c-bet spots should take DTO’s Grinder tier and be happy. A live player who opens too wide from the hijack and studies on commutes should fix that leak first, and that fix costs $119.99 a year, not $349.99 up front.

What are you actually buying?

The DTO lineup takes a minute to decode, and searchers get lost in it, so here’s the map as of September 2026. DTO sells its tournament trainer under the name DTO Postflop on its pricing page; the app stores call the same product DTO MTT. A separate DTO Cash product covers cash games. And DTO Preflop is a third product: one-time chart packs for tournament preflop study, not included in the trainer subscriptions’ price.

DTO Preflop, the product ours gets compared with by name, costs $349.99 one-time for the Basic pack (18 common MTT stack sizes across 6-max raise-first-in, 6-max limp, 9-max raise-first-in and 6-max ICM scenarios), $899.99 for Advanced (17 further scenario sets with different stack distributions and limping strategies), and $699.99 for a final-table ICM pack covering 51 stack distributions at 6, 5 and 4 players. It’s a serious MTT study product. It is also tournament-only: no cash ranges, no Spin & Go, and the trainer subscriptions are a separate purchase.

GTO Preflop ships everything as one library inside the app: 503 solved scenarios holding 11,385 decision points and just under two million hand-specific strategies. That covers cash at 50BB and 100BB raked tables plus 100BB and 200BB straddle tables, MTT ChipEV at 14 stack depths from 3BB to 100BB with antes, and Spin & Go at 17 equal-stack depths from 1.5BB to 34BB plus 418 asymmetrical stack combinations, from 2-handed to 8-handed. If you want the theory those files encode, our starting hands chart guide and MTT stack size guide walk through it position by position.

The honest asymmetry runs the other way too: DTO’s store listing claims over 100 million presolved MTT and SNG scenarios on the postflop side. We have zero postflop content. That’s the trade in one sentence: their depth is postflop tournament spots, ours is the complete preflop layer across three formats.

How do the trainers compare?

DTO’s trainer is the reason the product exists, and the drilling loop is good: pick a scenario, play hands against the solution, get graded. The catch sits in the tier ladder. On the Grinder plan ($9.99/month, 31 training spots) the grading is what DTO’s own pricing page calls basic evaluation: no EV loss, no frequencies. Right or wrong, nothing else. A mixed-strategy hand that bets 55% and checks 45% marks you wrong on a coin flip and tells you a 0.02bb miss and a 4bb punt are the same mistake. Exact EV loss and optimal frequencies arrive at High Roller, $29.99 a month, with 85 spots. The Super High Roller tier ($99.99/month) adds the full range explorer, currently ten ICM spots and four heads-up spots. There’s also a Virtual Coach that explains moves in plain language, powered by OpenAI, available to subscribers.

GTO Preflop’s trainer grades every decision against the solved strategy and shows the EV consequence at every price point, because there’s only one: Pro. You see EV loss per decision and EV loss per 100 hands, and an ELO rating moves with your play, so this week’s number tells you whether your preflop game beat last week’s. Achievements mark the milestones. Sessions fit in five minutes because the app was designed for a phone first.

One limit to know before you buy, because we’d rather you hear it from us: the trainer doesn’t drill everything the charts cover. It deals cash spots across the full 50BB to 200BB range and tournament spots from 3BB to 12BB, the depths where push/fold and re-jam decisions decide tournaments. Spin & Go ranges and deeper MTT stacks are reading material in the range viewer, not dealable drills. If short-stack play is what you’re fixing, our 4-bet ranges guide and 3-bet ranges guide pair well with those depths.

What do they cost in 2026?

All DTO prices below come from DTO’s own pricing pages, checked September 1, 2026.

Product Tier Monthly Annual / one-time
DTO Postflop (MTT trainer) Grinder $9.99 $89.99/yr
DTO Postflop (MTT trainer) High Roller $29.99 $269.99/yr
DTO Postflop (MTT trainer) Super High Roller $99.99 $899.99/yr
DTO Cash Beginner $9.99 $89.99/yr
DTO Cash Pro $39.99 $359.99/yr
DTO Preflop Basic — $349.99 once
DTO Preflop ICM — $699.99 once
DTO Preflop Advanced — $899.99 once
GTO Preflop Pro $19.99 $119.99/yr

GTO Preflop is free to download. Pro costs $19.99 a month or $119.99 a year on the standard plan, and a $7.99 weekly option exists 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.

Bar chart comparing dedicated preflop product prices in September 2026: DTO Preflop Advanced 899.99 dollars one-time, ICM 699.99 dollars, Basic 349.99 dollars, GTO Preflop Pro 119.99 dollars per year

The chart above compares the preflop products specifically. DTO’s defenders will point out, fairly, that the packs are one-time purchases: hold Basic for three years and it averages $116 a year, right at our price. The counters are what the money buys. The $349.99 pack covers MTT preflop only, at 18 stack configurations; $119.99 a year buys cash, MTT and Spin & Go preflop, EV-graded drilling included, on an app that still ships updates. And a tournament player who wants DTO’s trainer with EV feedback plus its Basic preflop pack is at $269.99 a year plus $349.99 up front in year one, about five times our annual price.

If the number you care about is a different competitor’s, our GTO Wizard vs GTO Preflop comparison runs this same exercise against the biggest name in the category.

Which is better on mobile?

Both products have real iOS and Android apps, which already makes this a fairer fight than most desktop-first tools manage. See our Equilab alternatives rundown for how rare that still is. The difference in 2026 is maintenance.

As of September 1, 2026, DTO MTT’s App Store listing shows version 8.1.11, last updated November 20, 2025, more than nine months ago. It holds a 4.7 rating across 282 US ratings. The Google Play build shows the same November 20, 2025 date, rated 4.3 across 1,200 reviews on 100K+ downloads. DTO Cash’s iOS app has sat at version 8.1.10 since September 23, 2025. The browser products are clearly alive; the phone apps haven’t shipped an update in three quarters.

Timeline of last shipped app updates: DTO Cash iOS September 2025, DTO MTT both stores November 2025, GTO Preflop Google Play May 22 2026 and App Store May 26 2026

GTO Preflop shipped version 3.0.30 on iOS on May 26, 2026 and its current Play build on May 22, 2026. It holds 4.8 across 240 ratings on the US App Store and 4.6 across 3,250 reviews on 100K+ Google Play downloads. It runs natively on iPhone and iPad (iOS 15.6+), Android, and Apple Silicon Macs.

A nine-month-old binary still works today. What it tells you is where the vendor’s attention is, and whose roadmap your subscription is funding. Ours is the phone app; that’s the whole company.

We can add one data point nobody else has here. We run Apple Search Ads for GTO Preflop, so we see which brand names people type into App Store search right before installing our app. In the 30 days to August 11, 2026, searches for DTO’s brand produced attributed GTO Preflop installs, and DTO-brand keywords have been producing paying GTO Preflop subscribers since at least spring 2026. Attribution only catches a floor of what searchers do, but the direction is clear: some players shopping for DTO on a phone are choosing the app that was built for one.

Where DTO Poker genuinely wins

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

  • Postflop tournament drilling. The core DTO product has no equivalent in GTO Preflop. We stop at the flop on purpose; they start there.
  • Pedigree you can verify. Dominik Nitsche has more than $21 million in live tournament earnings and built the tool he wanted as a player. That shows in the scenario selection.
  • Simplified strategies. Trimming solver output to fewer sizes and cleaner decisions is a defensible teaching philosophy, and DTO committed to it earlier than most of the market.
  • Entry price. $9.99 a month is a low door into structured MTT postflop study, as long as you understand what grading you get for it.
  • Final-table ICM packs. The $699.99 ICM pack’s 51 stack distributions at 6, 5 and 4 players is deeper dedicated final-table preflop coverage than we ship.

What we’d push back on is the shape of the ladder. The feedback that actually teaches, EV loss, starts at $29.99 a month. The preflop depth costs $349.99 to $899.99 on top. By the time a serious MTT player assembles the pieces, the budget argument has quietly left the room.

Switching from DTO to GTO Preflop

What you keep: solver-derived preflop ranges for every seat, a trainer that grades against the solution, ICM-free ChipEV baselines at every common depth, and tournament short-stack drilling from 3BB to 12BB where jam/fold decisions live.

What you lose: everything postflop. The spot library, the simplified postflop strategies, the ICM postflop sims. If your weekly routine leans on postflop drilling, keep DTO for that and treat this as an addition, not a switch; at $119.99 a year the overlap costs less than one month of Super High Roller.

Time to set up: minutes. Install, pick a format and depth, and start answering hands. The ELO rating calibrates itself over your first sessions, so the first twenty hands double as a preflop skill test. Most players find out fast that one of their opening ranges is wider than the solver’s. That first unpleasant number is the product working.

Tip:

Test the difference in feedback: get the app and run twenty trainer hands at a depth you play. Every answer comes back with the EV cost attached. If nothing surprises you, your preflop game didn’t need us.

DTO Poker vs GTO Preflop: FAQ

Is GTO Preflop a good DTO Poker alternative?

For preflop study, yes. GTO Preflop is a mobile preflop trainer and range library covering cash, MTT and Spin & Go for $119.99 a year, with EV-loss grading on every decision at every price point. It does not replace DTO’s postflop tournament drilling; nothing in our app deals a flop. Players whose leak is preflop get the relevant layer, complete, for less than DTO’s cheapest preflop pack.

How much does DTO Poker cost in 2026?

As of September 2026: the tournament trainer (sold as DTO Postflop, DTO MTT in the app stores) runs $9.99, $29.99 or $99.99 a month, or $89.99, $269.99 or $899.99 a year. DTO Cash is separate at $9.99 or $39.99 a month. The DTO Preflop chart packs are one-time purchases: $349.99 Basic, $899.99 Advanced, $699.99 for the final-table ICM pack. Free versions of the trainers exist with limited spots.

What’s the difference between DTO Preflop and GTO Preflop?

Different products from different companies, despite the similar names. DTO Preflop is a set of one-time tournament preflop chart packs ($349.99–$899.99) from DTO Poker, covering MTT scenarios only. GTO Preflop is our subscription app ($119.99/year) with solved preflop ranges and an EV-graded trainer across cash, MTT and Spin & Go.

Is the DTO Poker mobile app still updated?

The browser products are actively sold, but the mobile apps have gone quiet: as of September 1, 2026 the DTO MTT app was last updated November 20, 2025 on both the App Store and Google Play, and the DTO Cash iOS app has been on version 8.1.10 since September 23, 2025.

Does DTO Poker cover cash games?

Through a separate product. DTO Cash costs $9.99 a month (Beginner, aimed at NL2–NL25) or $39.99 a month (Pro, NL50+), each with 17 training spots as of September 2026. Its own pricing page lists shortstack, deepstack and heads-up spots as coming soon. GTO Preflop includes cash preflop ranges at 50BB–200BB, straddle tables included, in the same subscription as MTT and Spins.

Which is better for MTT players?

Depends on the layer you’re studying. DTO is the deeper postflop tournament tool, and its ICM packs go further on final-table preflop than we do. GTO Preflop gives you ChipEV ranges at 14 depths from 3BB to 100BB, drills the 3BB–12BB decisions that decide short-stack play, and grades them with EV loss included at $119.99 a year. Plenty of tournament players run both: DTO for postflop rehearsal, GTO Preflop for the preflop reps between sessions.
