Can someone tell me about slimming world please

[CottonSock]

I need a kick up the arse as gave gained a stone this year.
I've done slimming World principles before but never joined.

To get the app would I need to pay for group as well as online membership? I think going to group will motivated me. But I want access to the online stuff too.
Thank you

I'm a member.
I use the online stuff/app for checking syn values of food.
There's a food tracker as well that's handy when you start.
There are magazine articles on the app, and exercise videos. Recipes.

I don't know whether there's other stuff available only for online members, or whether it's all the same stuff that's available if you join a class.
I get what I need from group.

@picklemewalnuts thanks very much. Good to hear I probably don't need both memberships to get the app and stuff.
