I'd say no.
It does nothing you can't do yourself for free. But it seems to make the act of spending money so tedious that you probably won't bother. Maybe that's how it works?
Instead of paying £12.99 a month, you could arrange your money into pots/accounts.
You can have as many of these you like, but you need some for:
direct debits for monthly bills
annual/irregular things like Christmas, insurance, car repairs etc
emergency fund/large purchases, that sort of thing
holidays, split all these how you like depending on priorities/spare money
Do not spend from the above. They don't exist - if you need to spend on these things, it either happens by DD or you can spend if you need MOT etc.
Have an account for food/travel, only buy food and petrol from this account.
Have standing orders feed all the above accounts on payday. Once all the above accounts/pots are set up, apart from making sure the SO goes in, they don't need much input.

Then we get to the money you're allowed to spend on whatever you like. Feed it monthly into your spending account once you've sorted the above. When the money runs out, stop spending until next month. If it runs out too fast, you need to work out how to make more money, cut some of your other costs, or decide which of your vices you do and don't like and prioritise. If you don't spend it all one month, you have more to spend next month.
