What you log
Add the girls you're seeing. Then, after each date, log one entry: who it was with, what you spent, how long it took and how many nuts. Notes are optional.
That's the whole data model, and it's small on purpose. Anything slower than a few seconds per date stops getting used by month two.
What it calculates
Headline numbers: total spend, cost per nut, total time and total nuts across your whole roster.
Per-girl breakdown: every girl ranked by what she costs you per nut, per hour and in total. This is the view where most of the "oh" moments happen.
Charts: spend, nuts and cost per nut at a glance, so you don't have to read a table to see who's expensive.
Leaderboards
Private, opt-in leaderboards let you and your mates compare CPN inside a group you create. Only people you invite can see them. There are no public profiles and no feed.
You control what shows up: leaderboard visibility and an anonymous mode live in Settings → Privacy.
Share cards
Turn your CPN into a branded graphic for the group chat, Instagram or TikTok, without screenshotting your dashboard.
Your data
Your entries are private by default. We don't sell your data or use it for advertising. Delete your account from Settings and every girl, entry and leaderboard membership tied to you is deleted with it.
