PokerCruncher

Version 1.1 (Released Oct. 27, 2008)

• Product launch.

Version 1.2 (Released Nov. 16, 2008)

• New ":1" button that shows all stats as n:1 odds ("odds against", not "odds in favor"). Toggles between %age's and odds.
• More accuracy in the %age's: show 3 significant digits; used to round to nearest tenths.
• Show players' cards in the "i" stats view.
• Minor bugs fixed in the updating of the "Hands/Draws" button in the "i" stats view when DealTo=Flop, and in the resetting of stats.
  

Version 1.3 (Released Dec. 19, 2008)

New "Rnd" button that assigns random player and board cards.

• If you select any player card, the "Rnd" button assigns random cards to all players that you haven't assigned cards to. So for example you can enter pocket aces for Player1 (you) and tap the "Rnd" button to generate random cards for the other players.
• If you select a flop/turn/river card, the "Rnd" button generates a random flop/turn/river.
• The "Reset" button has a new option for clearing only the random player cards.

You can use this feature to generate random practice/test scenarios and test your odds estimates against the simulator's at each street: preflop, and after a random flop, turn, and river.

Version 2.0 (Released Feb. 9, 2009)

Hand Ranges!

• Select a player field, then tap the new "Rng" button on the card keypad to construct and assign hand ranges.
• Full grid of all 169 starting hands like PokerStove (the excellent Windows PC app).
• Convenient directional select/add/remove buttons that make constructing hand ranges easy even on a small screen.
• Extensive built-in hand ranges: pairs (all, high, medium, low), broadway/medium/low cards, connectors (also 1-gap, 2-gap, 3-gap), Ax, Kx, Qx, suited/offsuit.
• The 8 Sklansky hand groups are also built-in hand ranges, and our new Group 1a.
  

Version 2.1 (Released Mar. 2, 2009)

Some small new features and UI improvements, suggested mostly by two customers after the V.2.0 hand ranges update (thanks for writing):

• New button "Fold/Un-Fold Selected Player" under Menu button; models dead cards.
• New button "Reset All Except NumPlayers" under Menu button.
• UI now shows Equity for players 1..4 if there are more than 4 players (used to show Equity only for players 1..2).
• Renamed the "i" (stats) button to "S" and made the "S", ":1", "?", "X" buttons a little bigger so they're easier to tap.
• New "?" help button in the Built-In Hand Ranges screen, and added a note "Tap Add/Remove after selecting" in this screen.
• Reduced the default number of hands that are simulated by 10%..20% so calculation finishes a little faster (without sacrificing accuracy noticeably). You can always calculate again to get a new Monte Carlo result.
  

Version 2.2 (Released Mar. 24, 2009)

New hand ranges features. Driven mainly by good customer feedback; thanks for writing.

• Select top x% of hands slider in hand range builder screen.
• %age indicator for the hand range you're building: Shows the %age of all possible hole-card hands that are in the hand range, taking assigned (non-live) cards into account. This is also the odds of the player getting a hand in the hand range.
• Save/load hand ranges (up to 6 ranges). The Save/Load buttons are under the Menu button in the hand range builder screen.
• Small performance improvement in the responsiveness of the UI. E.g. adding/removing players is a little faster. We'll be investigating performance more in the future (e.g. calculation speed).

Version 2.3 (Released Apr. 28, 2009)

Select suits in hand ranges. Suggested by more than several customers, thanks for writing.

For example you can now enter the hand range Ahxh (h=heart) instead of just Axs (s=suited) e.g. if the flop has exactly two hearts and you want to put a player on the (heart) nut flush draw. You can select any combination of suits.

• New "Suits" button in hand range builder screen that brings up the suit combinations view.
• Single-select mode: If you have only one grid cell selected then the "Suits" button shows you the suit combinations that are enabled/disabled for the cell. You can toggle any of the applicable suit buttons on/off.
• Multi-select mode: If you have more than one cell selected (e.g. by selecting one of the built-in hand ranges) then all of the applicable suit buttons start out dimmed. Any on/off changes you make to any of the suit buttons will have effect on all of the applicable selected cells.
• New "Select" button in hand range builder screen that lets you multi-select ranges of cells in the 3 directions right/down/diagonal.
• New "View Hand Range Text" button under the hand range builder screen's Menu button, to let you see the complete text for long hand ranges.
• New built-in hand ranges Jx, Tx.
  

Version 2.4 (Released May 26, 2009)

NOTE: This update changes the storage format for hand ranges to fix a save/load bug. Please clear all old hand ranges (Menu -> ResetAll). Also please clear any hand ranges you may have saved in the hand range builder screen. Or, you can delete this app from your device (which will delete all of its data) and re-install it. Apologies for the inconvenience; we don't expect to do this again.

• Tap and swipe hand range grid cells to select and multi-select them - horizontally, vertically, and diagonally.
• Show Equity as the main player stat (used to show Win%).
• Equity colors: Green for positive equity (5% or more above breakeven), Orange for negative equity, Yellow for breakeven equity.
• New Deal-To-Flop "S" Stats view stats: combination draws, Pair&Draws. Tap new <- and -> buttons in Stats view to see the 3 groups of stats.
• Fix calibration of "select top x% of hands" slider. Now uses the odds of the hands in the hand range instead of using a linear (odds unweighted) hand ordering.
• Fix a hand range save/load bug - sometimes the wrong suit combinations were being loaded in. Please see the NOTE at the top.
  

Version 2.5 (Released Jul. 03, 2009)

Fix a save/load app state bug that's visible only on iPhone OS 3.0.

Version 2.6 (Released Jul. 21, 2009)

Ability to mark deck cards dead/live:

• First select Menu->SetNextDeckCardDead/Live.
• Then tap a deck card to mark it dead/live.
  

Version 2.7 (Released Aug. 25, 2009)

Range equity breakdown heat map and detailed stats.

Now, in addition to a range's overall equity you can see the equity of each hand in the range (shown as a color-coded equity heat map). You can also see what %age of the range each hand comprises (by viewing the detailed stats).

• Do a calculation that involves a hand range (or multiple hand ranges).
• Tap on a player's hand range to select it.
• Tap the new "R.B." (Range Breakdown) button - shows the equity heat map.
• Tap the "View Details" button to see detailed stats for all of the hands in the range - equity and %age of the range.
  

Note that due to Monte Carlo (random sampling) simulation, each hand's (grid cell's) equity has a higher variance (margin of error) than the entire range's equity.

Also a bug fix - sometimes the players' hand distributions and draws stats were being reset too early.

This range equity breakdown feature was suggested by customer M.S., thank you M.S.! We look forward to all suggestions, feedback, and reviews.

Version 2.71 (Released Sep. 14, 2009)

Improvements to range equity breakdown heat map and detailed stats ("R.B." button):

• Use a continuous range of colors red -> yellow -> green instead of 5 discrete-level colors.
• "View Details" stats: Show the range's total number of hand combinations and each cell's num hand combs.
• Use white color (instead of light-gray) for cells that are in the range but that don't have any assignable hands.
  

Again I'd like to thank customer M.S. and PokerCruncher's TwoPlusTwo forum posters for excellent suggestions. We look forward to all suggestions, feedback, and reviews, thank you.

Version 2.81 (Released Oct. 06, 2009)

Cards and odds format improvements:

• 4-color cards for easier readability of suits.
• New (saved) setting in the Menu for 2-color or 4-color.
• Small improvements to the design of some cards e.g. the Ace's inner suit icon is now a large suit icon not small.
• Better n:1 odds format: now n is always >= 1.0. "n:1" means "odds against" as before, and "n:1F" means "odds in favor" or "odds as a favorite".
• Change app display name to "PkrCruncher" (used to be "PokCruncher").
  

Thanks to PokerCruncher's TwoPlusTwo forum posters for these suggestions. More improvements and new features to come ...

Version 2.82 (Released Oct. 29, 2009)

New setting in the Menu for number of hands to simulate (for Monte Carlo simulation).

• "2 x Default" (or 4x) is recommended for 3GS devices.
• Infinite calculation mode.
• Stop/Continue calculation.
  

Misc:

• Update app icon.
• Rename TopPairOrBetter Deal-To-Flop stat to HitBoard'sTopCard to make its name match its meaning better. E.g. this stat can tell you how often AK (or JT, ...) hits at least top pair on the flop. Also, enable this stat for pocket pairs, so e.g. this stat can tell you how often a pocket pair flops top set (or top quads).
• Add "<-- Back" buttons in the Menu.
  

Version 2.91 (Released Nov. 13, 2009)

Export a hand to email.

• New Menu option "Export Hand ..." (shows the hand text including calculation results).
• Then tap "... To Email".
  

You can then email the hand text or copy/paste it elsewhere or ...

Version 2.92 (Released Dec. 10, 2009)

UI improvements:

• New button "Add+" in hand range builder screen. E.g. for 88 it adds 88+ i.e. AA-88, similarly for suited and offsuit cells. (Thanks funkyj on TwoPlusTwo.)
• Improve how players' equities are colored green (positive equity), yellow (breakeven equity), red (negative equity): Use 10% above/below breakeven equity as the green/red boundaries, instead of absolute/fixed 5% away from breakeven equity. E.g. now for AA vs. 9 random hands, AA is green and the 9 random hands are red. Before, AA was green but the 9 random hands were yellow.
• RangeBreakdown equity heat map: Add a slider to specify the top and bottom boundaries of the green --> yellow --> red color spectrum instead of hardcoding to absolute 30% above/below breakeven equity.
• Make "reset all" menu commands red (to indicate destructive).
• ExportHand and RangeBreakdownDetails popups: Remove the titles of the popups to make more space for the body text.

If you like PokerCruncher, or don't and have suggestions for improving it, would you please consider writing the app a review in iTunes? Or you can post on our TwoPlusTwo forum thread. Thanks for your support.

Version 3.0.1 (Released Jan. 29, 2010)

• New "flop hit" stats.
• Make the "Deal To" feature clearer in the UI.
• Some small UI improvements.

Details below (are also posted on our website's Purchase page). Many thanks for your reviews and emails and discussions/suggestions on TwoPlusTwo, -RJ

(1) New "flop hit" stats:

These stats measure a hand's direct/full hit on the flop, whereas the default "make hand" stats include cases where e.g. the board pairs to help make the hand.

Set DealTo=Flop and calculate. The "Stats" button toggles between "HitSt" ("hit hand" stats) and "DfltSt" (default "make hand" stats). In the Stats view, the hit stats which can be different than the default stats are shown in blue color.

"Flop hit" stats require the player's hole cards to be used to hit the hand. The default "make hand" stats don't require the hole cards to be used (can use only the board's cards, or can use the hole cards partially). For example AK's default "make hand" stat for OnePair on the flop is 40%, but AK's "flop hit" stat for OnePair is 29%. Similarly for TwoPair, 3OfAKind, FullHouse, and a few of the combination draws stats.

Thanks to a poster on our TwoPlusTwo forum thread for this suggestion.

(2) Make the "Deal To" feature clearer in the UI:

• Color the DealTo indicator (dotted vertical line) blue instead of gray so it's easier to see/notice, and so it matches the color of the new "flop hit" stats. Also make the DealTo indicator and the new "flop hit" stats bold.
• Show an alert explaining the DealTo feature the first time "Deal To" is tapped (show only the first time).

(3) Small UI improvements:

• Add "Export(Email)" buttons to RangeBreakdownViewDetails and ViewHandRangeText popups.
• Rename "Reset Hand Range" Menu command to "Clear Hand Range" in hand range builder screen.
• Indent hand range top x% slider and heat map slider a little more on the left hand side of the screen so they're easier to adjust.
• Rename "S" stats button to "Stats", rename ":1" button to "n:1", and make these buttons bigger so they're easier to tap.

Version 3.1.1 (Released Feb. 19, 2010)

Hand ranges improvements:

• Use "+" notation in a hand range's text, e.g. "JJ+" instead of "AA-JJ".
• Ability to enter an optional name for saved hand ranges.
• Show a confirmation alert when a hand range is saved.
  

Menu commands improvements:

• Reorganize the Menu commands into two groups: "Reset" button in the toolbar, and a new "Menu" button in the main screen.
• New Reset commands: "Reset Players", "Reset Board", "Reset Dead Cards".
• Move "Cancel" button to the bottom of the list in all menus, per standard UI convention.
• Make "Start New Calculation" button red (destructive) in Calculate menu.
• Rename "Clear Hand Range" button to "Reset Hand Range" in hand range builder screen's Menu.

ICM Cruncher

Version 1.0 (Released Dec. 07, 2009)

• Product launch.

Version 1.1 (Released Dec. 16, 2009)

Cleanups to the first release:

• CallAnAllInOrFold decision analyzer: This analyzer now requires you to enter the Villain's entire StartingChipStack in his ChipsPutIntoPot field, because the Villain has raised all-in. Before, this analyzer required you to exclude the Villain's all-in excess amount, which gave correct ICM calculations but didn't look intuitive because the Villain is all-in.
• Improve the wording in some error messages. Add error messages for cases where you have more than 1 villain due to the ChipsPutIntoPot values you've entered (the analyzers handle only 1 villain and 1 hero).
• Make the "Reset All" command red (to indicate destructive).

---

Hold'em Odds Quizzer

Version 1.1 (Released Dec. 8, 2008)

• Product launch.

Version 1.2 (Released Dec. 22, 2008)

New buttons "+ 5%", "+ 1%", "- 5%", "- 1%" to give you another way to set your answer for each question.

The original way is the slider and it's still there, but some users may find the buttons more convenient.

Version 1.3 (Released Feb. 27, 2009)

An Odds Tutorial screen that:

• Explains what "Equity" means.
• Shows you how to use the Outs Chart.
• Explains our method for estimating the odds for just about any Hold'em scenario in your head in real time by counting outs and counter-outs. This is of course a much better and more general way to learn poker odds than by memorizing the odds for specific scenarios or even by memorizing an outs chart.

These explanations were suggested by a customer, thank you.

Version 2.0 (Released Apr. 3, 2009)

Two new hand ranges quizzes: pre-flop and post-flop. This was suggested by our customers; thanks for writing. You may find that these hand ranges quizzes are harder than the non-hand-ranges quizzes.

Poker is a game of incomplete information; we can almost never put our opponents on specific cards. We have to put them on ranges of hands (e.g. "I think he has Aces or Kings or maybe AceKing") and make odds estimates based on incomplete information.

Version 2.1 (Released Jun. 27, 2009)

Thank you for suggesting these improvements:

• Show questions in random order in all quizzes.
• Added about 40 more situations: For more variety, most of the pre-flop and post-flop basic and advanced questions now have 2 variations (specific situations) per question instead of just 1 as before. The quizzer selects a variation randomly each time a question is shown.
• Added a Pre-Flop Odds Chart for common pre-flop matchups in the Tutorial.
• Show odds as both %age's and as n:1 odds, including in the Outs Chart.
  

Version 2.2 (Released Sep. 15, 2009)

New quiz: multi-player scenarios. 10 new questions, 2 variations per question, so 20 new situations added.

Example questions in the multi-player quiz: AA vs. 4 random hands, TopPairTopKicker on flop vs. FlushDraw vs. OpenEndStraightDraw.

Version 2.3 (Released Oct. 06, 2009)

Cards and odds format improvements:

• 4-color cards for easier readability of suits.
• New (saved) setting in the Menu for 2-color or 4-color.
• Small improvements to the design of some cards e.g. the Ace's inner suit icon is now a large suit icon not small.
• Better n:1 odds format: now n is always >= 1.0. "n:1" means "odds against" as before, and "n:1F" means "odds in favor" or "odds as a favorite".
  

Thanks to PokerCruncher's TwoPlusTwo forum posters for these suggestions.

Version 3.0 (Released Oct. 20, 2009)

Major V.3.0 update - Worldwide high-score leaderboards for each quiz and for overall odds knowledge!

.. using OpenFeint 2.2 for the leaderboards. OpenFeint is a leading social game community that also features chat and friends. If you don't have an internet connection, you can store your scores locally on your device as before.

To get going, launch the app, enable OpenFeint when asked, go to the Results screen, and tap "Post Scores" to post all of your current scores. Then take more quizzes and post up-to-date scores.

• You get a score for each quiz now in addition to a grade. Your score is computed from your grade (accuracy), quiz completion time, and number of answers cancelled.
• Worldwide high-score leaderboards for each quiz.
• Leaderboard for a new aggregate quiz "Overall Odds Knowledge" that sums up the 7 important "base" quizzes. Whoever's at the top of this leaderboard is the current reigning overall odds champ!
  

Also:

• Made the "Submit Answer" button a little bigger (taller) to make it easier to tap.
• Your average %age error for a quiz is a little more accurate now: it's rounded up/down to the nearest integer instead of just being truncated downward to an integer.
  

Version 3.0.1 (Released Nov. 07, 2009)

Minor bug fix update:

• Fix a "resume quiz after quit/restart app" bug - If you quit the app right after answering a quiz's last question (i.e. when you're looking at the "Quiz Finished" alert), and then restarted the app, the app was resuming the quiz at its last question. Now the app recognizes that the quiz is finished and doesn't resume it.

Resume after quit/restart was working correctly for questions 1 .. n-1, so this bug shouldn't have caused too much trouble; was introduced in V.3.0, apologies.

Poker Odds Teacher

Version 1.0 (Released Mar. 24, 2009)

• Product launch.

Version 1.1 (Released May 22, 2009)

As you suggested:

• Added about 10 more practice scenarios.
• Reworded Step3's instructions to make the %age adjustment (the subtraction) for counter-outs clearer.

Version 1.2 (Released Aug. 15, 2009)

Fix a small bug that's visible only on iPhone OS 3.0 - the last scenario in each of the 3 groups wasn't being shown in the popup lists. So now 3 more scenarios are visible.

Version 1.3 (Released Oct. 06, 2009)

• 4-color cards for easier readability of suits.
• New (saved) setting in the Menu for 2-color or 4-color.
  

Thanks to PokerCruncher's TwoPlusTwo forum posters for these suggestions.

Version 1.4 (Released Nov. 11, 2009)

Improve the layout of the 3 main groups' select scenario popup lists. They don't scroll now so the buttons are easier to tap.

Version 1.5 (Released Dec. 19, 2009)

Improve the usability of the sliders as suggested by a couple of iTunes reviews:

• Indent the sliders on the left side instead of placing them flush against the left side of the screen.
• Instead of using slider min/max values 0%..100%, use 0%..75% or 0%..50% (depending on the slider) so that specific %age values are easier to select.
• Use min/max values 0..15 for the number of outs sliders instead of 0..21, again to make specific values easier to select.

Thank you for writing the reviews and letting us know how to improve this.

Version 1.6 (Released Mar. 09, 2010)

Clarify the last step's (step 3's) answer result screen:

• Show (1): the app's method's expected answer, in addition to (2): your estimate and (3): the actual (exact) answer (obtained e.g. from an odds calculator). Up til now the app has been showing only the latter two ((2) and (3)).

Note that the app's method only gives a good estimate, not the exact answer. Thanks to a couple of customers for suggesting this clarification.

Small UI improvements:

• Move "Cancel" button to the bottom of the list in all menus, per standard UI convention.
• Show a confirmation alert when the card colors setting has been changed/set.
