The betting performance platform
Back yourself. With evidence.
Ball Sentry is the betting performance platform: pro-grade research, machine-read signals, strategy testing, and a verified record of what actually works — for you, personally. Stop renting picks. Build your own edge.
Every bettor has a number.
Sample scoreThe Sharp Score measures betting quality — closing-line value, discipline, selectivity — never your last hot streak. Tap a component:
Edge evidence. Do you beat the closing price? The single best predictor of long-term profit — hot streaks can’t fake it.
Six ranks, one ladder: Mug → Syndicate. Tap a rung — where do you land?
Yours unlocks free: import your betting history (10 graded bets) — most imports unlock it instantly. Ranks grade betting quality, never future winnings.
The alternative you already know
Why not just pay a tipster?
£30–50 a month buys you someone else's picks and a record you can never verify. Ball Sentry is the anti-subscription to that: stop renting someone else's picks — build and prove your own.
Their record
Unverifiable. Screenshots, cherry-picks, deleted losing months.
Your record here: graded against closing odds, every bet.
Their incentive
Keep you subscribed, month after month.
Ours: make you self-sufficient.
Their picks
Take it or leave it. No context, no history.
Our Signals: suggestions with a published, audited history — you make the call.
The loop
Research it. Build it. Paper-test it. Prove it.
Everything a tipster pretends to do, made yours — with the one thing they will never show you: a verified record of what actually works, for you, personally.
Research it
Fixtures, odds, form, H2H and market movement — the same desks the pros use, in one place.
Build it
Turn a hunch into a system: markets, staking rules and Guard limits, planned before emotion enters.
Paper-test it
Run the strategy with zero money and full rigor — settlement, CLV, the lot — until it earns a stake.
Prove it, then stake it
Every bet captured and graded against closing odds. When the evidence says it works, graduate it to live.
Recording a bet in Ball Sentry does not place it with a bookmaker. Paper streams stake nothing at all.
The full walkthroughs
Every desk, explained in under a minute. Plain English, real product.
The Free Betting Audit
Bring your history. Get your verdict in minutes.
Upload bookmaker CSVs, bet-slip screenshots or pasted text. Ball Sentry parses, grades and settles the lot — then shows you your real P/L, your closing-line value, your three biggest leaks and whether it looks like skill or luck. Free, private, no card.
- CSV exports. bet365, Sky Bet and a generic template parsed instantly
- Screenshots. Bet-slip images read for you — you confirm every bet
- Review before commit. Nothing enters your record until you approve it
Dan's audit — the film (1:50)
Dramatised composite · not an actual customerSignals & the Engine Room
A predictions engine with nothing to hide.
Our Predictions Engine reads dozens of live signals and surfaces suggestions — with its full audited record published, wins and losses. It is improving constantly, and Signals are suggestions, never instructions. You're always the one making the call.
Complete record
Every prediction settled and graded — losing runs included.
Quarantine discipline
Suspicious data is excluded, publicly, not massaged.
You vs the engine
Log follow, fade or pass — your report scores your calls against it.
Luck is loud. Edges are quiet.
Here's how we tell them apart.
Try it - the variance lab
Four seasons. Same bettor. Zero edge.
Every line below is the same simulated bettor: 40 bets at odds of 1.90 with no edge at all. The spread between the best and worst season is pure luck - yet one of them would feel like skill and another like a crisis.
Variance is loud. Leaks are quiet. A tracked record is how you tell them apart before the difference gets expensive.
Educational simulation with random outcomes. It is not a prediction, a model output, or a promise about betting results.
Best season
+9.4u
Worst season
-9.6u
Best season dip
-3.1u
Try it - staking maths
How long a losing run can your bankroll absorb?
Drag the sliders. Aggressive staking quietly shortens the losing run you can survive - and losing runs are guaranteed to happen. Stream Guard enforces stake and odds caps like this on every decision you record, so the plan holds up on a bad week.
Flat-staking illustration only. It is not staking advice and says nothing about how often you win.
Straight losses before you are down half the bankroll:
25 bets in a row
patient
Try it - the numbers in plain English
Tap a metric. No jargon, no homework.
Profit and loss
The cash result of every settled bet added together - not just the wins you happen to remember.
Why it matters: It answers the baseline question most bettors cannot: are you actually up or down?
58 settled sample bets -> +£84.20.
