Another vote for myfitnesspal I have it on my phone and kindle as apps but you can access on Pc as well. My favorite feature - after you finish a daily entry they post 'if you ate like this every day you'd weigh ###.# in 5 weeks"
I love that motivator. If you join friend me (and anyone else too) I love to see other peoples inspirational success on the timeline. My mfp name is intrinsicat
Good luck!
I'm a MPF user also. I just started in May. My sister lost over 70 lbs with its help. Feel free to friend me.
