How Cost Per Nut Works

Every interaction is a single row of five fields: date, person, spend, time, outcome. The whole app is built around that minimal data model because the minimal model is the only one that gets used in month four.

Logging takes about thirty seconds. You can do it from the rideshare home and you're done. The friction is intentionally lower than any spreadsheet or notes-app workflow — the app is designed around the assumption that anything slower than thirty seconds dies in real life.

Monthly CPN: the headline number. One scalar on the screen, updated as you log new dates.

Per-girl breakdown: a sorted view of every person in your rotation with spend, outcomes, and CPN. The view that produces most of the insights.

Trend line: monthly CPN over time, plus a three-month moving average. Optimization is invisible at any single point and obvious in the trend.

Spend categories: pie chart of where the dating dollars are going. Restaurants, bars, transport, gifts, activities. Often a surprise — the big buckets are usually the ones nobody was tracking.

Private opt-in leaderboards let you and your wingmen compare CPN within a small group. The numbers stay in the group. No public profiles, no random feed.

The social layer is opinionated about privacy: you're the only person who sees your raw data; your friends only see the rolled-up number you choose to share. Most groups settle into monthly leaderboard cadence with light banter — the natural habitat of the metric.

Shareable graphics: drop your monthly CPN into a clean branded card, suitable for the group chat or social posts. Built specifically so you don't have to screenshot a dashboard.

Data export: every byte of your data is downloadable as CSV at any time. The app doesn't lock anyone in. If you want to leave or maintain your own backup, the export is one click.

Your data is yours. We don't sell it, we don't share it, and we don't run analytics on it beyond what's needed to operate the app. There's no public discovery layer, no algorithmic feed, no public profile. The app is a private tool, and that posture is non-negotiable.
