CitrusFi: A subscription audit that actually understands billing cycles

CitrusFi is a small subscription tracking app that answers a question most trackers get wrong: "how much am I really spending per month?"

Most subscription lists just show you a pile of prices with different billing cycles (some monthly, some yearly, some weekly) and leave you to do the math. CitrusFi normalizes everything into a true monthly equivalent figure a $15/year membership contributes $1.25/month to your real total, not $15. It also shows the honest annual total alongside it, so nothing is hidden or confusing.

It's built for anyone who's ever been surprised by how much their subscriptions actually cost once you add them all up properly.

Code

My Build Process

Built with Claude as my technical partner via Command Prompt on Windows. Hit network drops during npm installs (fixed with cache clears), a folder conflict setting up the Sanity Studio (fixed by making it a separate folder), and a calculation bug where yearly subscriptions weren't counted correctly (fixed by normalizing all billing cycles to true monthly-equivalent cost, shown alongside the real annual total).
