Thanks a lot guys! I completely agree with you. I use Jivaro now and as you said, it's very simple HUD with excellent graphics and very easy to use, and yeah, I can't review session after the game and it works only on PokerStars.So, I understand that it is not a pro tool like as pt4 / hm2 but it offers an excellent introduction into how HUD actually works, I'm sure, for beginners like me this is very important thing, once you realize how HUD works , you can use any of them..
When I started the poker tracker for the first time I had a lot of problems to manage with all these numbers, but now I am sure it would be much easier.. So, if anyone looking for the first HUD, try Jivaro, and then you can easily move onto pt 4 or hm2..
One more thing, if you do not play multi tables, you no need any tracker.. It is enough to look closely at a few hands and you will have the necessary information.. Of course, this is just my experience in a very short time..
