It is obviously to pay for all of the R&D they've been doing to update APDL.
Awesome.
Yeah, I've given up and just gone to doing my logbook by hand again. I got tired of waiting for APDL to come out of 2004 and into 2010 with an iPhone or Android version. It appears that NC Software is afraid of new technology since by the time they brought out LBP by itself for the iPhone, it was about 2 years late to the party. Android? Forget about it. Windows Phone 7? Doubtful. I loved APDL on my old Palm 650, but I'm not carrying that thing around just to input my leg times when I can just log into the computer and do it myself.
He's probably charging $5 a month because his revenue stream is drying up.....
