I'd like to start recording every penny I spend so I can track better, and I want to record it myself so I know eg my total sainsburys bill included some food, a gift, pyjamas for me, cat food etc, rather than just being recorded ad "groceries". I don't want an app to have access to my bank accounts and select the category itself. Does anyone have any recommendations? I'm considering doing it on paper but thought an app might be easier.
