Why keep a betting log
Memory flatters. Most bettors remember the long-priced winner and forget the run of small losses that came before it. A written log settles the question with numbers: after fifty bets you can see which markets pay you and which quietly cost money – the same test our leaderboard runs on the model.
Pair the tracker with level stakes – the same small share of your bankroll on every bet – and review it monthly with the ROI calculator. If the log shows you betting more than you planned, take a break and read our responsible gambling page.
Bankroll tracker: a betting log that stays on your phone
The bankroll tracker is a simple record of every bet you place – stake, odds, result – that works out your balance, profit, hit rate and ROI as you go. Everything is saved only in your own browser. We never see it, and nothing is sent anywhere.
Why keep a record?
Betting without a record is guessing about your own results. A log shows you exactly where money comes from and where it goes: which markets work for you, which leagues cost you, whether accumulators are helping or hurting, and whether your stakes creep up after a loss.
How to use it well
- Set your starting bankroll – money you can afford to lose and nothing more.
- Log every bet at the moment you place it, including the ones you would rather forget.
- Mark results as soon as they are known.
- Review once a month, not after every bet.
What to look for in your log
- Stake drift: are your stakes growing after losses? That is chasing.
- Market differences: a market with a high hit rate and negative ROI is costing you money.
- Accumulator share: if accas take most of your stakes and few of your profits, cut them back.
Pair it with the Academy
The tracker works best alongside a staking plan. Our bankroll management lesson explains how big each stake should be, and the ROI calculator helps you read the totals. Because the data lives on your device, export it now and then if you change phones. 18+.
Worked example: what a log reveals
After three months, a punter's log shows 180 singles with an ROI of +3% and 45 accumulators with an ROI of −38%. Overall, the account is down. Without the log, it feels like "a bit unlucky"; with it, the fix is obvious – keep the singles, shrink or drop the accas. Another log shows stakes averaging ₦1,000 after wins and ₦1,900 after losses: classic chasing, invisible until written down. A betting log is not admin; it is the most useful tool most punters never use.
Tracker checklist

Quick answers
Is my data safe? It never leaves your device – we cannot see it.
What if I clear my browser? The log is deleted, so export it regularly.
Can I track several bookmakers? Yes – add the bookmaker name to each bet's note and review them separately.
Should I log free bets? Log them separately, so your real stakes and returns stay clear.
What is the most useful number in the log? ROI by bet type. It shows which habits make money and which ones cost it.
Can I set a starting balance again? Yes – but do it at your monthly review, not after a bad day. Resetting after losses hides exactly what the log is for.
Does the tracker work offline? Yes – once the page has loaded, you can log bets without a connection.
Frequently asked questions
Where is my data stored?
Only in this browser on this device. Nothing is sent to Winning Arena. Clearing your browser data removes it, so export a CSV now and then.
Can I use it on my phone and computer?
Each device keeps its own log. Export the CSV from one and keep it as your master record.
How should I size my stakes?
A common rule is 1–2% of your bankroll per bet, kept level whatever the last result. The tracker shows your current bankroll so you can resize once a month.
