About Cost Per Nut

Why we built it, what it's for, and who it's for.

What we're building

Cost Per Nut is a dating ROI tracker. Dating is one of the biggest discretionary spends in a single guy's life, and it has never had its own tool. Budgeting apps see the totals. Notes apps see the receipts. Nothing connects spend, time and outcomes the way the math needs.

The product is opinionated: CPN is the metric, and the per-girl breakdown is the headline view. Everything else stays out of the way.

Who it's for

Single guys who already have a dating life and want to understand what it costs. The app doesn't help you get more dates. It shows you what the dates you're already having cost you.

It also works for guys early in a relationship who want to keep an eye on spend.

Who it's not for

Guys looking for dating coaching or pickup advice. CPN is a measurement tool, not a coach.

Guys looking for general budgeting. Apps like YNAB and Copilot are better at household finance, and we don't try to compete with them.

Anyone uncomfortable with the framing. The product is named what it's named for a reason. If that's not for you, that's fine.

Our philosophy

Your data is private. We don't sell it, share it or build a public social product on top of it.

Friction kills tracking. Logging a date should take seconds, not minutes.

Numbers are numbers. We don't soften bad results or wrap them in motivational copy.
