Who out there is also doing WW along with MFP?

I have been on WW for 2 years now and after the initial 30 lbs lost, I have been in a rut. I have been up and down between 243 and 252 and it's just getting ridiculous. I have been terrible at tracking with WW, but that's mostly because WW doesn't have an app for my Kindle, where I do most of my online work. Anyways, I haven't quit WW, it's where I weigh in once a week and get my encouragements from the members. We are more like a family than just a group. But I added MFP to help me with counting carbs and tracking. Just wondering who else out there does this and have you had much success???
