What you're building

You're building the app that answers 'wait, how much am I actually spending on subscriptions?' -- add every recurring service you pay for (monthly or yearly), and it normalizes everything into a single combined monthly total, saved permanently to localStorage. It's the kind of tool that pays for itself the first time it makes you cancel something.
