The Cost Per Nut App

Log a date in seconds, watch your CPN update, and see the per-girl breakdown that shows where your dating money actually goes.

Spend totals, nut counts, time tracking, cost per hour, charts and private leaderboards. None of it needs setting up.

3-day free trial, then $4.99 a month or $27 a year. One plan, Player Mode, with everything included.

Cancel anytime in Settings → Manage billing. Cancel before your 3-day trial ends and you pay $0.

Your data is private by default. We don't sell it or share it. There are no public profiles and no social feed. Leaderboards are opt-in and limited to private groups you create.

You can delete your account and all of your data from Settings at any time.

CPN is a web app. It runs in Safari or Chrome on iPhone, Android and desktop, so there's nothing to download. On iPhone, tap Share → Add to Home Screen and it opens like an app.

Tap Calculate my CPN and answer a few quick questions. Create your account, add your first girl, log a date and your first number appears.

From there: log dates as they happen and check the numbers whenever you want a reality check.
