The Sports Betting Bankroll Tracker 90-Day Journal Review

TL;DR

The Sports Betting Bankroll Tracker is a 90-day paper journal designed to make daily bet logging unavoidable. Each page has fields for bet date, sport, market, stake, odds, expected outcome, actual result, and a notes column. It's not a spreadsheet replacement for analytical bettors who model positions — but for the larger group of recreational bettors who say they track and never do, paper-on-the-desk is the friction that finally makes logging happen.

Why It Matters

The single biggest gap between profitable bettors and losing bettors is honest record-keeping. Without a log, you remember the wins and forget the losses, which means your sense of "how I'm doing" is reliably wrong. Whether you log on paper or in a spreadsheet matters less than that you actually do it. Paper has the advantage of being right next to the laptop.

Won't survive a coffee spill

Who It's For

Recreational bettors who keep telling themselves they'll track and don't. Anyone trying to build the habit before graduating to a spreadsheet. Bettors who think better with a pen than a keyboard. Skip it if you already maintain a clean spreadsheet (don't downgrade) or if you want analytical features (use Excel/Google Sheets/dedicated bet trackers).

How to Use It

Log every bet before the result is known — including the projected outcome. After the event, fill in actual outcome and a one-line note on what you learned. Do the monthly summary even if it stings. After 90 days, decide: stay on paper, or graduate to a spreadsheet with the habit you've built.

How It Compares

Vs. spreadsheet (Excel/Google Sheets): spreadsheet is more powerful; paper is more disciplined. Vs. dedicated bet-tracking apps (Action Network, etc.): apps offer charts and EV; paper offers focus. Vs. no tracking: night-and-day improvement.
