I have an HTC droid Phone. I'm an avid chess player and have seen on some forums that Pocket Fritz 4.0 will theoretically work on Android Phones !? I hope I don't need any of the Windows Mobile apps for it to work on my phone. I have mobile office on my phone. I also have Windows 7 on my computer. The Windows mobile software is very expensive. can someone please share information on system requirements as well as patches and upgrades for Pocket Fritz 4.0 (ie 4.3 that will make it work on Windows 7.
