I found all the different diet options confusing. I only manged to do one week, i guess if you want to eat what they suggest, it may be fine, but i wanted to swap every meal, which takes ages, so other than the 1st week when i was really keen, i have not bothered. there is no actual contact other than emails each week to encourage or help so if you are looking for support, you would probably be better at a weekly class, no one appears to have noticed that i have not logged in to the app from week 2. I have not followed it so needless to say i am still the same weight as when i started!
