I use mccPilotLog. Great program. Runs on MAC/Apple/Whatever and PC systems. I use it on my ipad, iphone, and PC. Easy to log, very user friendly, shows currency, graphs, charts, stats, everything you can think of. $100 for their premium version. No monthly fee, constant updates/improvements. They are fast in customer service.
