Easy to use Open Source Poker Tracker. For starters, it will only support Pokerstars. It is still in pre-alpha stage, so it is not ready for production use.
Feel free to report bugs to the github issue tracker or fork me on GitHub. As soon as the PokerStars import is finished, you can use it as template for your favourite Poker site.
