Betting Tracker

A brutally honest accountant for your wagers. Logs every bet, shows the real scoreboard, and tells you where your edge actually lives.

The Analogy

The accountant who doesn't round up.

Memory lies. Every bettor remembers the big wins and quietly forgets the slow drip of losing Monday night props. That selective memory is what keeps losing bettors convinced they're winning, and winning bettors convinced they're breaking even.

This tool is the honest ledger. Every bet goes in. Every result comes out. The dashboard shows you your real profit, your real ROI, and which bet types you actually beat the market on — not which ones you feel good about.

You can't fix what you don't measure. You can't measure what you won't log.
How It Works

Log. Aggregate. Reveal.

Input
Every bet gets logged.
Wager, odds at bet time, market, sport, book, stake. Either typed in or pulled from a sportsbook export.
→
Transform
The numbers get crunched.
Calculates P&L, ROI, hit rate, and closing line value — the real measure of whether you beat the market or just got lucky.
→
Output
You see the truth.
Dashboards sliced by sport, market, bet type, and sportsbook. Where you're crushing it. Where you're bleeding.
Under the Hood

What's actually running.

Ledger Bet Database Stores every wager — the source of truth. Structured so slicing by any dimension is a trivial query.
Calculator P&L Engine Runs the math — unit size, variance, closing line value — the metrics that separate real signal from noise.
View Layer Interactive Dashboard Charts and filters that let you zoom into any segment — one sport, one book, one bet type — in a click.
Privacy Private by Default Lives behind a password gate. The data is personal, and the tool is built to keep it that way.
Why it's built this way

The value of a tracker is proportional to how easily you can ask a hard question of it. "Am I actually good at NBA player props?" should take five seconds to answer, not an afternoon of spreadsheet wrangling. Structure the data once, and every question becomes cheap.

Why It Matters

Betting is a business if you want it to be.

Serious bettors run their action like a portfolio: tracked, analyzed, pruned. Casual bettors run theirs on vibes. The gap between those two ways of operating is the gap between a hobby that pays and a hobby that bleeds.

This tool exists to close that gap. It's not trying to pick winners — that's a different tool (see Project № 06). It's trying to tell you, with zero ego, where you're actually winning.
