@Splendud I use MyNetDiary. There are some premium features but if you press the cross in the corner, you can just use the diary, food scanner and weigh charts.
I didn't lose last week and had already ordered a 7.5 pen because I felt it was still working. I kept getting hungry at the end of the week, so I counted the clicks to increase to 10 on Saturday.
I've already lost 2lb ... a total of 34lbs now in 16 weeks!! That's 18% of my body weight!!
