I bought it last night from the itunes store keep up the good work!

second plug but i use this alot. esp when talking w ppl about ranges, math and ****.

i love breaking down shortstack shoving calling ranges while taking a ****.

this is sweet and any poker player w an iphone should have this.

Thanks 99, NotLolo - reading good feedback like this makes all the work and TLC I put into the app more than worth it! V.2.3 will go live in about 3 weeks.

I am about to purchase this, it looks like you did a good job with it man!
Excited to see all the free updates come out, and where this program goes!

Another data point: bought it yesterday and messed around with it in the car while waiting for my daughter's piano lesson to finish. Great value for five bucks. Thanks, Raju.

Thanks jewbelieve, sapientia for writing. For me it's not really about trying to make a lot of $ one copy at a time (but nice if that happens), but just to have a darn good mobile calculator that will be useful even for advanced players. You can count on this app getting better. More later..

On the deal to flop stuff, could you create a histogram that shows the equity after the flop vs the range instead of the distribution of hands by type. A lot of the types of hands overlap which makes a big difference. Knowing that you're going to flop a certain hand x% if the time is not that helpful. Basically what I'd like to see is the % of the time a hand is going to have >90% equity, 90-80%, 80-70%, etc.

Also have you looked at any performance enhancements? It's kinda slow. Are you using the open source pokersource code?

The odds seem a little off vs pokerstove. For example AhAc vs 8c7c, pokerstove shows 78.094 vs 21.906, your app shows 77.7 vs 21.9(btw what is that number you have equity underneath that says 77.9 vs 22.1). I guess you're adding the ties into the wins? If so you should put the equity at the top and the win% separate. Then on AcKc vs AhKh it says the clubs are a .2% favorite... Something is wrong.

Hello Av9114, thanks for looking at the app closely.

Re. deal to flop - Yes I'll consider the histogram you're suggesting in a future update (but not the next one). But it will be in addition to the current hand histogram view not a replacement because I think the current histogram does give useful info. E.g. you may want to limp or call preflop raises with marginal/speculative hands like 1 or 2-gap suited connectors and the current histogram view shows how often you can expect to get miracle flops like trips/straight/flush, and also shows how often you can expect to flop strong draws e.g. a flush draw or an open ender. This helps to decide if you want to pay for that preflop raise (bunch of other factors of course like position, stack sizes, amt of preflop raise, player styles, etc.).

Re. performance - yeah I'd like it to be faster too and think this can be improved. Part of the reason is the CPU speed vs. desktops but the other reason is I'm using a "naive" ad-hoc evaluator not the open source ones. One reason is that PokerCruncher computes a lot more stats than these optimized evaluators (not just win/tie/equity), e.g. odds for flopping various draws (including gutshot draws), or having top pair or better on the flop, or having an overpair on the flop. So I made a more stats and generality vs. speed tradeoff. But this doesn't mean I can't make it faster in the future at least for some common cases.

The number at the top for each player is Win%, then Tie%, then Equity. I like your suggestion to put Equity at the top because it's the most important stat. The only reason I put Win% at the top is that I think people understand this stat better and it's more familiar. Some people have sent emails asking what Equity means, totally understandable, whereas they understand Win% right away.

Re. the odds being off - I'm going to need more evidence! I simulated AhAc vs 8c7c in the app fives times and got: 78.0, 78.1, 78.4, 78.0, 78.1. You said PokerStove shows 78.094. PokerCruncher does a Monte Carlo simulation not exhaustive so a few tenths of a percent error is within the error range (the 77.7 that you got). Same for your AcKc vs AhKh case where the app says the clubs are a .2% favorite; this is within the limits for any Monte Carlo simulation. PokerCruncher does do complete exhaustive enumeration for some "easy" cases e.g. if all player cards are assigned and are specific cards and the flop cards are assigned, so only the turn and river are unknown which is just ~1000 combinations so the app enumerates them all and computes the exact answer.

If there's something wrong with the numbers I'll definitely fix right away but can you pls. give more evidence/cases/info.? Can you run your cases a few more times and compare? Anyone else see problems? Thanks for getting the app! I'll repeat my mantra - the app will get better. Thanks for the feedback everyone, -RJ

Thats exactly what I was asking for. Honestly, I think the current ones are pretty pointless. In fact I'd go so far as say that if you actually make poker decisions based on them you should re-examine the way you think about the game, but I do understand why some people would want them and it doesn't hurt to have them as well. Actually I've gone back and forth regarding how useful the deal to ____ is in general, one of the reasons I know about the open source libraries is because I was thinking about making this myself.


I don't think its a CPU issue, pokerstove uses almost no CPU time on my computer. I just tested a preflop all-in and it hit 5% for a second on a vista VM. From what I've read about PokerStove, there is a ton of optimization built in. I feel pretty confident that you could get PokerStove type optimization without losing the extra stats. I do realize that this is a much more complicated solution and would require a lot of work.

If you put equity at the top it won't have a label and people won't ask questions

okay. I didn't realize that it was a monte carlo. For the record I only really bought it because I believe that you want to make it better and it is moderately useful as is. I'm probably going to continue to use twodimes.net if I have any sort of internet connection though, even though being a couple tenths off isn't a big deal its going to bug me.

You're the first person to tell me that the Deal-To-Flop feature and the additional stats are pointless or even detrimental to good poker thinking. But I can understand this; different people think about the game differently, which is what makes for good games. But note that a couple of iTunes reviewers on this app have talked about this feature favorably e.g.:

"Also, PokerCruncher has some nice displays for the odds of catching draws of various kinds which helps you to understand whether or not your opponents might have hit a flop, for example."

and,

"... one that I like is how often will your pair of 10s see an overcard on the flop (or turn or river)."

I'm not saying there's a right or wrong answer here. If I get more feedback to the effect "this is bad, get rid of it" of course I'll rethink this feature. It would be great if others could give more feedback on the Deal-To-Flop feature and the hand histogram stats and the odds for draws stats. Afaik no other odds calculator anywhere combines Deal-To-Flop and these additional stats so I admit this is a new non-standard feature.

I'm hoping I can move you into the "very satisfied" camp on the app (and off of twodimes, doesn't even have hand ranges!) at some point in some app update in the future. May take a long time, even in V.3.0 and I may have to work hard on e.g. performance or a non-Monte-Carlo exhaustive but fast technique (that can still compute this variety of stats), but, it's not supposed to be easy right .

Thanks for feedback, always good to get both positive feedback and ways to improve feedback, -RJ

Android port, kplzthx.

I bought the iPhone app today, just one day after buying the iPhone itself!

I just wanted to tell you that I love it so far. No, the results are not instantaneous, nor are they accurate to the hundredth of a percent mathematically ... but you don't claim that they are! The program calculates based on Monte Carlo sims, so you expect a slight variation. At least I do. It's good enough to give you what you want/need. For those that are so precise in their play that the extra 0.5% will make a difference to their strategy ... well, then they're much better players than me!

Also, to give another user's viewpoint to a couple of the issues raised thus far:

1) Complaints about the speed. Yes, it's a little slow. But, it's not THAT slow. You get your results back in 10-15 seconds, it seems. That's plenty fast enough for it to be practical. There was the complaint that it's useless for online play because it is so slow. I suppose that's true, but why would you use your iPhone for caclulations when you're playing online ON A COMPUTER that has access to other speedy computer-based tools? Are these people playing on Windows 3.1 and can't switch to another window?? LOL ... Personally, I play mostly live, and this app is absolutely wonderful for that scenario.

2) The "Deal to..." feature. I think it's just fine. I've not seen any other simulator/math program that includes this type of information. So, I give you kudos for that. It can be very useful information for an astute player. But, like any other type of information, it can be harmful if used incorrectly. So be it. Personally, I think the feature is great, especially the "draws" section.

Nice job overall. It can use some improvement (what can't?), but it's a very useful product right now, especially for us mostly-live players.

I have no complaints about the speed, and I think the deal to flop feature is extremely valuable and an antidote to over-relying on hot/cold equity simulations. Not sure what Av9114's point is, but I think many players either under or overvalue calling raises with speculative hands, and knowing exactly where you will be on the flop can be very eye opening. Obviously, stack sizes, opponents tendencies, position, etc, are all important to factor in, but if you think you are going to flop strong with 67s 1/3 of the time or only 1/10 of the time, you are so wrong that everything else doesn't matter.

One feature request: the histograms draw screen would be even better if it told you how often you flop draw combinations, i.e. open ended + flush draw, fd + gutshot, etc.

Thanks for feedback guys esp. on Deal-To-Flop and speed. Jacksin, super that you like the app, the app is honored to be one of your phone's firsts : ).

The next two updates are set now:

- V.2.3 - Suits in hand ranges, so you can enter e.g. Ahxh instead of just Axs, say if the flop has 2 hearts. You'll be able to edit the suits of any of the 169 cells like you can in PokerStove. (Will go live in about 3 weeks)

- V.2.4
- Move Equity stat to the top (instead of Win%) [Av9114].
- Draw combination stats in Deal-To-Flop [DesertCat].
- ... and more UI/stat type stuff. I'll be going through all the emails and threads to collect.

Thanks for all the feedback, -RJ

In all seriousness, I suddenly want to buy an Iphone.
