Preflop ranges,
solved.
Pick a seat, set a percentage, and see which of the 169 starting hands to open. Solved charts add mixed frequencies and per-hand EV, and the coach answers questions about why a threshold sits where it does.
The chart app is free, works offline, and needs no account.
Live from the app’s real hand ranking — drag the slider or pick a seat.
One product, three surfaces
The same ranges, wherever you study
The web app is the workspace: big grids, EV columns, the coach. The phone apps are the reference you actually have on you. They read the same hand ordering, so a range you learn on one is the range you see on the other.

What’s inside
A range chart that shows its work
Most preflop charts are a picture of somebody’s opinion. This one is generated from a ranking you can read, and — where a solve exists — from solver output you can interrogate hand by hand.
Every seat, every table size
Heads-up to full ring, under the gun to the big blind. Each seat ships with a sensible default opening percentage, and you can overwrite any of them.
Percentages that count deals
The top 40% of the squares on a grid is only about 32% of the hands you are actually dealt — offsuit hands are 12 combinations each and they fall out of a range first. Drag the slider and watch both numbers; most charts only ever show you the flattering one.
GTO preflop solutions
Solver-derived strategies with the mixed frequencies intact: the hands that raise 70% of the time look different from the hands that always raise.
Per-hand EV
How many big blinds a hand is actually worth in that spot. It is the number that tells you which mistakes are cheap and which are expensive.
One canonical hand order
The chart, the rankings screen and the apps all read a single generated ordering. If they ever disagree, the build goes red before you ever see it.
Your colours
One colour, yours — the whole app takes it, light and dark. Plus a simple mode that strips the screen back to one grid and one slider.
AI poker coach
Ask why a hand is where it is
You can memorise that KJo is a fold under the gun and a raise on the
button. Knowing why — that it is dominated by exactly the hands
that continue against an early-position raise, and that the button gets to steal
two blinds against two players instead of eight — is what transfers to the
hand you have never seen before.
The coach in the web app answers in plain English and is grounded in the same solution set the charts are drawn from, so it quotes real frequencies and real EV rather than inventing them. Ask it about a hand, a seat, a threshold, or the spot you just misplayed.
A5s a raise from the cutoff but A9o isn’t?A9o is ahead of the hands
that fold to you and behind almost every offsuit ace that calls — it is
dominated when it gets action. A5s is behind more hands on raw
strength, but it makes the nut flush, it makes wheel straights, and it blocks
A5s-type calls and ace-x continues. Playability and blockers beat
a slightly better high card here.
A9o there?Illustrative exchange. The coach is part of the web app.

FAQ
Common questions
What is a poker range calculator?
A poker range calculator turns one number — the share of hands you want to play from a given seat — into the exact set of starting hands that makes it up. Texas hold’em has 169 distinct starting hands; the calculator ranks them, draws them as a 13×13 grid, and lights up the ones inside your range, so you can learn a threshold instead of memorising a list.
Is Poker Range Calculator free?
The chart is free on iOS and Android: no account, no ads, and it works offline. The paid tier adds the parts that come from solving rather than ranking — formats and stack depths beyond the free 100bb cash-game slice, the per-hand EV column, and the AI coach.
What is a preflop range chart?
It is the standard 13×13 grid of every Texas hold’em starting hand: pocket pairs run down the diagonal, suited hands sit above it and offsuit hands below. A preflop range chart colours in the hands you play in a given situation, so an opening range is a shape you can recognise at a glance rather than a list you recite.
What does “GTO preflop” mean?
GTO stands for game-theory optimal: a strategy that cannot be beaten in the long run by any counter-strategy, even one that knows exactly what you are doing. A GTO preflop solution is not a raise/fold list — it is a set of frequencies, where a hand might raise 68% of the time and fold the rest, plus the EV of each option. It is a baseline to deviate from deliberately, not a script.
How is an AI poker coach different from a range chart?
A chart answers “what”; a coach answers “why”. An AI poker coach reads the same solution data the chart is drawn from and explains it in plain English — why a hand sits just inside a range, which hands dominate it, what changes when you move one seat. That reasoning is what transfers to the spots no chart covers.
Which positions and table sizes are covered?
Every seat from under the gun to the big blind, at tables from heads-up (2 players) to full ring (10). Each seat has a default opening percentage for each table size, and you can save your own numbers over any of them.
Can I use it on the web, or only on my phone?
Both. The iOS and Android apps are on the App Store and Google Play today, and the web app runs in any modern browser with nothing to install. The web app is in alpha while the deeper tooling lands.
Does it need an account or an internet connection?
No. The chart works fully offline and stores your settings on your device. An account only matters if you buy a subscription and want it to follow you to another device.
Am I allowed to use a range calculator while I play?
It depends on where you are playing, and you should check first. Live card rooms generally do not want phones or notes in use while you are in a hand. Online, rules vary by site: many permit static charts but prohibit any tool that is fed your actual hand in real time. This app is built for study away from the table — that is also where it does the most good.
