I tried the site yesterday, down,, so I downloaded the app, quite what it does that 10+ year old pre-existing websites don't already do (apart from a thin veneer of BS about what your money is spent on) is beyond me. Try adding tax on petrol, heating, alcohol, cigarettes, VAT, etc and then give us a figure (i.e. add 20% to the figure that HMRC gave you).
