CPN

Cost Per Nut

CPN Features

What the app actually does, in feature-by-feature detail.

Core: date logging

Thirty-second entry: date, person, spend, time, outcome. That's the entire form. We don't ask for venue, mood, weather, or anything else that doesn't compute into the metric.

Quick-add from the dashboard: the most-used flow is the floating add button that drops you into the logging form. No menu, no submenu, no setup.

Dashboards

Monthly CPN headline: one big number on the screen, current month, recomputed as you log.

Trend line: monthly CPN over time with a three-month moving average. The single most useful chart in the app.

Spend breakdown: pie chart by category (restaurants, bars, transport, gifts, activities). Reveals where the money actually goes.

Per-girl pivot: sortable table of every girl in your rotation with spend, outcomes, CPN, and last interaction date. The view that produces most of the actionable insight.

Leaderboards

Private opt-in groups: invite your wingmen, share rolled-up CPN, compare numbers within a closed circle. No public discovery layer.

Multiple groups: separate leaderboards for separate friend groups. Your fraternity-brother group doesn't have to see the same numbers as your work-friend group.

Custom periods: monthly is the default; the app also supports weekly and quarterly leaderboards for groups that want different cadences.

Share cards

One-click branded graphics that summarize your monthly CPN, suitable for posting in your group chat or, if you're brave, social media. We bring the visual design so you don't have to.

Multiple templates: a clean minimal one, a chart-heavy one, a comedy-style one with the savage commentary baked in. Pick the one that matches your mood.

Data and privacy

CSV export: one click, full data, downloadable any time. You own your data. We make leaving easy as a matter of principle.

Account deletion: also one click, also irreversible. We mean it about owning your data.

No data sales: we don't sell, share, or rent your data to anyone. The business model is the subscription, full stop.

Coming soon

Native iOS app: in development. The web app is intentionally responsive and works fine on mobile, but a native app is on the roadmap.

Comparison reports: anonymized aggregate benchmarks so you can see how your CPN compares to the broader user base (by city, age, etc.).

Direct expense imports: optional connection to your bank or card so dating expenses can be pre-tagged for you. Aggressively opt-in, fully reversible.
