What is a poker tracker, and what is it for?

A poker tracker is software that reads the hand history files your room's software already writes to your disk, and turns them into numbers: what you win, with which hands, from which position, how often you raise. You stop estimating.

Are you winning, losing, or breaking even? And by how much? If you cannot answer to the number, format by format, you are playing without knowing where you stand. That is the first question a tracker answers.

The rest is what makes it worth it. A tracker does not only say how much, it says where: winning on the button, losing in the cutoff, a hole in the small blind. Those are the spots you work on next, and without measurement you do not even know which ones exist.

The file does not hold only your hands, it holds the whole table. So the same tracker also tells you who you are up against: who opens too wide, who never pays, who folds the moment you bet the flop. Your game on one side, the players you face on the other.

This guide covers what a tracker measures, which statistics to read first when you start using one, and how to use it to find what costs you. Poker Toolkit is building its own: see the free poker tracker.

How does a tracker get your hands?

A tracker reads your hand history, a folder of text files your room's software writes on your computer itself, and nothing else: it does not look at your screen and does not talk to the room. Where that folder lands and what you find in it depend on the room.

The writing happens on its own, and each file describes the hands in order: who was seated, who bet what, which cards were shown at showdown, who took the pot and how much rake was taken along the way.

Why install a tracker as early as possible?

A tracker only produces reliable stats with volume, and it can only use the hands it has read. Installing it early fills the database while the files are still there, before the room's software deletes them.

Two settings decide what your tracker will be able to tell you in six months:

• Writing the history is sometimes off by default. It is switched on in the software's settings. While it is off there is nothing to read.
• The files are often deleted after a few weeks. A tracker installed today does not recover what has already gone. That is the one good reason to install it before you need it.

Which statistics matter most?

VPIP, PFR and 3-bet. These are the three that even the rooms' own software sometimes displays by default: they are enough to spot the big mistakes and to profile a player's preflop behaviour within a few dozen hands.

What is VPIP in poker?

VPIP is the percentage of hands where you voluntarily put money in the pot. The blind you pay does not count, since you did not choose it.

What is PFR in poker?

PFR is the percentage of hands you raise preflop. It is always lower than or equal to VPIP, since raising already means putting money in the pot of your own accord.

What is a 3-bet in poker?

The 3-bet is how often you re-raise after an opponent opens. It is the first of the three that depends on someone else, not only on your cards.

That is why it swings so much depending on who opened. Against a UTG open, which is tight, you 3-bet little: their range is strong. Against a button open, which is very wide, you 3-bet far more. A global 3-bet of 6 % says almost nothing until you break it down by position.

How do you combine VPIP, PFR and 3-bet?

By reading them together. The gap between VPIP and PFR says whether a player is passive or aggressive, and the 3-bet says what they do when someone has already raised in front of them.

A VPIP of 28 against a PFR of 12 is someone who limps and calls far more than they raise: you value bet wide against them and you bluff little. VPIP and PFR close together and high is the opposite, a player who opens hard and is best left to hang themselves.

The 3-bet settles the rest. Very low, they only raise first in and let you open freely: you steal their blinds. High, they punish you the moment you open wide, and it is on you to tighten up. The other cross-readings are detailed in the stats a tracker calculates.

Which statistics should you read postflop?

The c-bet, the WTSD and the AF. The c-bet is how often you bet the flop after raising preflop. The WTSD is the share of hands seen at the flop that go to showdown. The AF is the ratio of your bets and raises on one side to your calls on the other.

Two more counters complete the picture by saying where the money comes from: winnings at showdown and winnings without showdown. The first come from pots won with cards on the table, the second from pots taken by making the other player fold. Lots of non-showdown winnings is a player who attacks and will make you fold; almost none is a player waiting for a hand. The detail is in the stats a tracker calculates.

Is your winrate reliable?

Not before a sample most recreational players never reach.

Over 5,000 or 10,000 hands a losing player can perfectly well be in the green. That is variance, not level, and it is what breaks the most mental games: you judge yourself on a sample that allows no judgement. Results tracking tells you where the money goes, format by format. It does not tell you in three weeks whether you beat your stake.

Why separate rake from your winnings?

Rake does not weigh the same across formats, and it costs the most where it shows the least. In cash game it goes out pot after pot without you noticing.

In spins it is folded into the buy-in but remains the heaviest of any format. On those two, rakeback weighs the most: what you claw back can be the difference between winning and losing.

In tournaments it is displayed up front next to the buy-in, so far more visible, and its impact seems less direct because one big result covers a lot of entry fees. The impression is false, but it explains why so few MTT players count it.

What does a tracker do for bankroll management?

It replaces an impression with a number, and it gathers what is scattered: if you play on several rooms, your real bankroll appears nowhere else.

From there you filter. Take the MTTs out to see what your cash game is worth on its own, isolate a stake, compare two months: that is how a trend appears, where a global balance only shows a number. It is also what makes a bankroll management rule usable, since it is only worth something if the number of buy-ins is measured. The detail is in bankroll tracking.

How do you know whether you play the range you built?

By putting the two side by side, which a tracker is the only tool able to do.

You built a button opening range, say 42 % of hands, and you revise it. The tracker shows, right beside it, the grid of hands you really open in that same spot. The gap between the two shows what you actually play against what you had planned.

How do you use a tracker to improve?

By starting from the spots where you lose. The tracker tells you which hands cost you and in which contexts: at which position, against which type of opponent, at which stack depth.

Spotting is immediate, fixing is not. Once the spot is identified, you still have to understand why you go wrong there, and that is where the work starts: you replay the hands in detail and build a study method around what costs you, instead of revising at random.

What a tracker measures

• Results: Exact wins and losses by format, rake counted separately, and the curve over time.
• Preflop frequencies: VPIP, PFR, 3-bet and blind defence, broken down by position.
• Postflop play: Continuation bet, showdown frequency, aggression by street.
• The range you actually play: The grid of hands you really open in a spot, set beside the chart you saved.

Which tracker should you choose?

It comes down to two questions, not to price: how many hands you can keep, and whether you can get your data out the day you stop.

Is it allowed?

It depends on the room you play at, and it is worth checking their terms before installing anything.

The usual dividing line is clear: storing and analysing your own history is generally accepted, while collecting hands you did not play, or trading them with other players, is prohibited everywhere. So is any software that takes a decision for you.

Frequently asked questions

What is a poker tracker?

Software that reads the hand history files your room's software writes and turns them into numbers: your results, your frequencies, and the play of the opponents you met. It does not play for you, it shows you what you did.

What is a poker tracker for?

Tracking your results format by format, reading your own stats to spot your mistakes, and reading your opponents' to find theirs.

What is the difference between a tracker and a solver?

A solver works out what you should play, in theory. A tracker measures what you did play, from your history. The gap between the two shows what to work on.

Which statistics should I look at first?

VPIP, PFR and 3-bet. VPIP is the share of hands where you voluntarily put money in the pot, PFR the share you raise preflop, 3-bet how often you re-raise.

How many hands before the stats are reliable?

A few hundred for VPIP and PFR, five hundred to a thousand for the 3-bet, tens of thousands for a winrate. Simple rule: the rarer the situation a stat covers, the more you need.

Where are the hand history files?

In a folder created by your room's software on your computer, often named « hand history ». Writing is sometimes off by default and the files are often wiped after a few weeks.

Are poker trackers allowed?

It depends on the room, to be checked in their terms. Generally: analysing your own history is accepted, collecting or trading hands you did not play is prohibited everywhere.

Can a tracker tell me why I am losing?

It tells you where, not why. It sees that you lose in the small blind or that you stop raising after a big hit; the why is yours to find, but on numbers rather than memories.

Do I need a tracker to improve at poker?

No, but without one you work on your memory, which keeps the spectacular hands and forgets the ordinary leaks. Those are the ones that cost, because they come back hundreds of times.

Does a tracker work on mobile?

Not for reading the history. The files are written on the computer you play on, so the software reading them has to run there too. Trackers are desktop applications.
