In my opinion Fitday needs to get a Android app developed quickly, in the meantime check out http://www.fitday.com/fitness/ForumRules.html, this apps kick it, with a barcode scanner for your foods and a GREAT database of foods!
I use fitday and recommend it to others on a weekly basis. Would love to have an app for my droid phone. I haven't checked out any of the barcode scanner apps - might have to consider that, but don't want to leave fitday!! Come on developers - I'll buy your app!
I have a droid and will never switch to Apple... here's another vote for FitDay to get a Droid compatible app... I have had both the FatSecret and SparkPeople one and like the FatSecret one because I can look up healthy options on popular restaurant menus - invaluable!
