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)

• 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.

Version 2.0 (Released Feb. 9, 2009)

• 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)

• 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)

• 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)

• 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)

• 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)

Version 2.6 (Released Jul. 21, 2009)

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

• 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.
  

Version 2.71 (Released Sep. 14, 2009)

• 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.
  

Version 2.81 (Released Oct. 06, 2009)

• 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").
  

Version 2.82 (Released Oct. 29, 2009)

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

• 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)

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

Version 2.92 (Released Dec. 10, 2009)

• 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.

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.

• Show an alert explaining the DealTo feature the first time "Deal To" is tapped (show only the first time).

• 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)

• 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.
  

• Reorganize the Menu commands into two groups: "Reset" button in the toolbar, and a new "Menu" button in the main screen.

• 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.

Version 3.1.2 (Released Mar. 22, 2010)

• Double-tap a player's card/range to bring up the hand range builder screen (as a shortcut to tapping the "Rng" button).
• New setting "Auto-Add Grid Cells" in hand range builder screen's Menu. If this setting is on then the grid cells are automatically added to the hand range when you tap/swipe the grid. If this setting is off then you have to first select the cells, then tap the "Add" button.
• Show the 3 main player stats in this order: Equity, Win, Tie, instead of the old order: Equity, Tie, Win. Make this change in Menu-->ExportHand too. This is the order convention in desktop programs.
• Bug fix (minor, harmless bug; no one reported this): When the recently added SaveHandRangeAs screen is being shown, if you tapped/swiped on this screen then the hand range grid (which is in the screen that's behind the SaveHandRangeAs screen) was picking up the taps/swipes and selecting grid cells. Now these taps/swipes aren't sent to the hand range grid.
  

Version 3.2.1 (Released Apr. 07, 2010)

• A further speedup if there's more than 1 hand range (on top of the 4x speedup).
• No big speedup for Deal-To-Flop; this case is about as fast as before (because of the extra stats).
  

• Show the number of simulations done next to the calculation progress bar.
• Remove the RoyalFlush stat, because the optimized hand evaluator doesn't calculate this stat.
  

• Rename "Num Hands To Simulate" setting to "Number Of Simulations".
• Rename "Export Hand ..." Menu command to "View Hand Text & Export ...".
• Rename "HitSt" (hit stats) and "DfltSt" (default make hand stats) buttons to "Hit" and "Make". These stats are only calculated for Deal-To-Flop.
  

Version 3.2.2 (Released Apr. 22, 2010)

• Add a note to the Help screen saying that the calculation engine uses Steve Brecher's excellent HandEval code for low-level hand evaluation. Thank you Steve.
• Plug in an updated version of HandEval that Steve Brecher sent us; uses less memory.
• Add "(enum)" to the number of simulations shown if the calculation is doing complete enumeration.
• For example:
• Complete enumeration: Show e.g. "990(enum)"
• Monte Carlo simulation: Show e.g. "200000"
  

• Clarify error messages and Help info. to say that selecting a card/range means tapping it (not assigning it), e.g. in the "RBrk" button's error messages.

Version 3.3.1 (Released Jun. 06, 2010)

• Color the range equity breakdown heat map's tap-able cell info. green/red/yellow (positive/negative/breakeven equity).
• Add a dead cards error message for an extreme edge case: when the simulator can't deal all cards because there aren't enough deck cards, because there are too many dead cards.
  

Version 1.0 (Released Dec. 07, 2009)

• Product launch.

Version 1.1 (Released Dec. 16, 2009)

• 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).

Version 1.2 (Released May 05, 2010)

• Put Cancel button at the bottom of all menus per UI convention.
• Dismiss the system keyboard if it's up (and in the way) e.g. when Calculate, etc.

• 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.

Version 2.0 (Released Apr. 3, 2009)

Version 2.1 (Released Jun. 27, 2009)

• 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.

• 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)

• 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.

Version 1.5 (Released Dec. 19, 2009)

• 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.

Version 1.6 (Released Mar. 09, 2010)

• 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)).

• Move "Cancel" button to the bottom of the list in all menus, per standard UI convention.

• Add "Stats" button; shows hand histograms for each player and for the winning hand.
• Add ability to edit/assign hand ranges and set DealTo = Flop/Turn/HoleCards, so you can take a look at these powerful features. But calculation of hand ranges and DealTo is enabled in only the full version.
  

• Show the number of simulations done next to the calculation progress bar.
• Add "(enum)" to the number of simulations shown if the calculation is doing complete enumeration, e.g. "990(enum)". Monte Carlo simulation is the default.
