I have installed the app on the Iphone and when I login in it keeps saying error, if I try to register it says that user name is already used, which it is.

i log in using facebook on the PC am I not matching something up right, Also I have a Nook touch tablet will rny talk work on that too,

Do I need to have you resend my password and username or change something so everything matches.

only thing I can suggest is to send a pm to Alex and maybe he can direct you. I use my Iphone and laptop with no problems

thanks Kristy I have messed up something but not sure what

I have screwed up something with my weight loss ticker and cant seem to get it back. Plus I hate the way it puts 3 decimal points :-(
