The 5 Best Cost Per Nut Trackers in 2026

There are exactly two kinds of "Cost Per Nut tracker" in 2026: tools purpose-built for it, and tools you can bend into doing it. We tested every credible option in both categories across five criteria: tracking quality, compatibility scoring, charts, privacy, and price.

Here's the ranked shortlist, plus a side-by-side comparison.

How we ranked them

Five weighted criteria — each scored 0–5 dots. We tested every option for at least 30 days of real logging.

• Tracking — how fast and frictionless is the daily logging loop?
• Compatibility — does it score the quality of the relationship, not just the spend?
• Charts — can you actually see trends, or just a single number?
• Privacy — is your dating data sold, shared, or scraped?
• Price — free is best; paywalls behind core tracking are penalised.

At a glance

1. nuttr — best overall (free)

Best for: anyone who wants the full CPN + compatibility picture without setup.

nuttr is the only app on this list that was designed from scratch around Cost Per Nut. Log a date, log a nut, get your CPN per person, per month, all-time, automatically. Add a Gottman-based compatibility score per partner — the only one of its kind in a CPN tool — and you get the full 2-axis view of every connection: what she costs and whether she's worth it.

Highlights

• CPN per person, per month, lifetime — auto-calculated
• 15-metric Gottman compatibility scoring with trend lines
• Calendar, history, and per-woman charts
• Relationship Mode — switches into coaching companion once you commit
• Free, no card, your data stays in your private account

Drawbacks

• We made it. Bias disclosure: ours is the highest-scored option for a reason — it's the only one built for this.

2. Custom Google Sheet / Notion template — best for spreadsheet purists

Best for: people who already live in spreadsheets and want zero third-party trust.

A well-built template is genuinely viable. Columns for date, person, type, amount, vibe, with a pivot table that sums spend, counts nuts, and computes CPN per person. Add conditional formatting for the green/amber/red buckets and you have a usable tool.

Highlights

• Free, total control, exportable
• No third party touches your data
• Customisable to whatever weird taxonomy you want

Drawbacks

• Manual everything. Logging a single date takes 60+ seconds vs 10 in a purpose-built app
• No charts unless you build them
• Most people quit by week 3 because of the friction

A reasonable starting template: Date | Person | Type (Date/Nut) | Amount | Vibe (1–5) | Notes with a pivot table grouping by Person.

3. Copilot / YNAB / Monarch — best for spend-only tracking

Best for: people who already use a budget app and just want to tag dating spend.

Connect your bank, tag every dating-related charge with a custom category ("CPN — [name]"), and you get the spend numerator automatically. You'll need to track the nuts denominator separately — a notes app works.

Highlights

• Spend tracking is automatic via bank sync
• Best-in-class budget visualisation
• Works for everything else in your financial life

Drawbacks

• Doesn't track nuts. Doesn't compute CPN. Doesn't do compatibility.
• $8–15/month
• Per-person tagging is doable but tedious

4. Dating journal apps (Iris, Honi, etc.) — best for sentiment, weakest for CPN

Best for: people who want to journal feelings about dates more than track money.

These apps focus on the qualitative side — how you felt, what you noticed, conversation notes. Some have rudimentary spend fields. None compute CPN automatically. None have compatibility scoring rooted in research.

Highlights

• Pretty UIs, prompt-based reflection
• Decent privacy posture in most cases

Drawbacks

• Not built for cost tracking
• No CPN computation
• $5–10/month for what amounts to a dressed-up notes app

5. Pen and paper — the control case

Best for: people testing whether they'll actually stick with the habit before downloading anything.

A small notebook in your back pocket. One line per entry: date, what, how much. End of month, add it up.

Highlights

• Maximum privacy. Nothing leaves your hand.
• Forces you to be honest — there's no autocomplete to lean on
• Free

Drawbacks

• No charts, no trends, no per-person view, no compatibility scoring
• You will lose the notebook
• Realistically, this is a 30-day experiment, not a system

The honest verdict

Use case	Pick
You want a real CPN with compatibility scoring, free	nuttr
You're a spreadsheet person and don't trust apps	Google Sheets template
You already use a budget app and want minimal new tools	YNAB / Copilot + notes app
You want a journal more than a tracker	Iris / Honi
You want to test the habit before committing to a tool	Pen and paper for 30 days

For 95% of people, the answer is option 1 — not because we made it, but because the friction reduction is the difference between a system that works and a system that dies in week three.
