Sure Bets App: How to Tell a Tipster App From a Real Arbitrage Alert
- A sure bets app can be a tipster app that picks one winner or an arbitrage tool that covers every outcome, and app store listings rarely make the difference clear.
- A real lock names a bookmaker, price and stake for every outcome, and you can check the maths yourself before betting.
- Genuine locks are small, with AUOdds data showing a typical lock of about 1.4% over the last 30 days.
- Win rates, single selections, unlicensed sites and claims of huge returns are warning signs of a tipping product.
- Even a real lock carries risk from moving prices, stake limits, voided bets and simple mistakes.
A sure bets app can mean two very different things, and the app store won't tell you which one you're downloading. Some are tipster apps that pick one winner and present it as certain. Others are arbitrage tools that cover every outcome across different bookmakers, so the return is locked in at the prices shown. This guide explains the real sure bets meaning, walks through a worked example of a genuine lock with stakes in dollars, and gives you a checklist of warning signs that expose a tip dressed up as a lock. It also covers what good arbitrage betting apps should display, and the risks that remain even when the maths works. AUOdds sends lock alerts, so we have a view, but every test here works on any app you are considering.

What is the sure bets meaning, and why do app stores mix it up?
In Australian betting talk, a sure bet is an arbitrage: you back every possible outcome of one event at different bookmakers, and the combined prices are high enough that the total return is roughly the same whichever result lands. Australians usually call it a lock. The word "sure" refers to the coverage, not to a prediction. You are not picking a winner at all.
The trouble is that the same phrase gets borrowed by tipping apps. Search an app store for sure bets and you will see listings like "Football Betting Tips" sitting right next to "Sure Bet Calculator". One is selling an opinion about who will win. The other is doing maths on prices. The store listing rarely tells you which is which, and the icons and screenshots often look almost identical.
That matters because the two products carry completely different risk. A tip is a single bet on one outcome. If it loses, your stake is gone, however confident the tipster sounded. A real lock spreads stakes across all outcomes so the result of the match does not decide whether you get a return; the prices you secure do.
A quick test works on any listing: ask whether the app tells you what to back, or tells you how much to stake on each side. If it names one team or one horse and stops there, it is a tipping app, whatever the title says. If it shows a stake for every outcome at named bookmakers, it is at least trying to be an arbitrage tool, and you can move on to checking whether its numbers hold up.
Sure bets app or tipster app: how do they actually differ?
Once you strip away the branding, a sure bets app built on arbitrage and a tipster app do different jobs. Here is how they compare on the points that matter:
- What you receive: a tipster app sends a selection, such as "Back the Storm at 1.80". An arbitrage alert sends an event, two or three bookmakers, the price at each, and a stake for every outcome.
- What decides the result: with a tip, the match result. With a lock, the prices at the moment you place each bet.
- What a loss looks like: a losing tip costs the full stake. A lock that goes wrong usually costs a smaller amount, typically because one price moved before the second bet went on.
- How claims are checked: tip records are often self-reported and hard to verify. A lock can be checked by anyone with a calculator, because the maths is on the screen.
- Typical return: tipster apps advertise big wins and strike rates. Real locks are small. Over the last 30 days, the typical lock in AUOdds data was about 1.4%.
The last point is the one that catches people. A tipster's pitch is built on excitement. An arbitrage alert is closer to a price feed: thousands of numbers, a few small gaps, and a stake split that has to be acted on quickly before the gap closes.
Neither type of app removes the need for your own judgement. But only one of them lets you verify, before you bet, what return you are locking in at the prices shown. That single difference is the most useful filter you have when the store listings look the same.
What does a real lock look like in numbers?
Here is a short worked example using a two-way tennis market, the kind of alert an arbitrage app might send.
- Player A: 1.95 at Bookmaker 1
- Player B: 2.12 at Bookmaker 2
- Total you want to put in: $500
First, convert each price to an implied probability by dividing 1 by the odds: 1 ÷ 1.95 = 0.5128 and 1 ÷ 2.12 = 0.4717. Add them together: 0.9845. Because the total is under 1, the market is a lock. The return at these prices is (1 ÷ 0.9845) minus 1, or about 1.57%.
Next, split the $500 in proportion to those figures:
- Stake on Player A: $500 × 0.5128 ÷ 0.9845 = about $260.50
- Stake on Player B: $500 × 0.4717 ÷ 0.9845 = about $239.50
Check both outcomes. If Player A wins, $260.50 × 1.95 = $507.98. If Player B wins, $239.50 × 2.12 = $507.74. Either way you get back roughly $508 for $500 staked, a return of just under $8, provided both bets go on at those prices.
Now compare the tipster's version. The app says "Banker: Player A at 1.95". You put $500 on Player A. If A wins, you collect $975. If A loses, you lose the whole $500. A price of 1.95 implies about a 51% chance, so the bet is roughly a coin flip with a confident label on it.
The lock is deliberately boring. That is the point: the match result no longer decides your return, only whether you got both prices before they moved.
Which warning signs reveal a tipster posing as a lock?
Plenty of apps put "sure" or "100%" in their names. Run any of them through this checklist before you hand over money or sign up for a subscription.
- Only one outcome is named. If there is no stake for the other side, it is not a lock.
- No bookmaker or price per outcome. A real alert has to say where each price is, because the gap only exists across different bookmakers.
- Win rates instead of margins. "92% strike rate" is a tipping claim. Locks are described as a percentage return at the prices shown, and that percentage is usually small.
- Returns that look too good. A lock of 1% to 3% is normal. Claims of doubling a bank in a week point to tips or aggressive staking schemes.
- Talk of fixed matches or inside information. Treat this as a serious red flag and walk away.
- Pressure to deposit with unfamiliar or offshore sites. Stick to licensed Australian bookmakers. The ACMA's "Check if a gambling operator is legal" page lets you confirm whether an operator is allowed to offer services here.
- Suggestions to bet in-play online. Online in-play sports betting isn't offered to Australians, so an app pushing it is not built for local rules.
- Multis labelled as locks. Accumulators multiply risk; they do not cover outcomes.
- No way to verify past alerts. A genuine service should be able to show the prices it sent so you can check them yourself.
If an app trips two or more of these, treat it as a tipping product, whatever its name or star rating says.
What should good arbitrage betting apps show you?
Genuine arbitrage betting apps fall into two groups. Calculators do the stake maths on prices you type in. Alert services scan bookmakers, find the gaps and send them to you with the stakes already worked out. Both are legitimate; the difference is who does the searching.
For an alert service, look for these features:
- Every outcome covered, with a bookmaker, price and stake for each.
- Fresh prices. Odds go stale quickly, so ask how old a price is when it is compared. For reference, AUOdds data shows about 15,000 prices tracked at any moment, typically about 10 seconds old, across 9 bookmakers, with 3,749 locks found in the last 30 days and 887 in the last seven.
- Licensed Australian bookmakers only. More bookmakers means more chances to find a gap, but only if they are licensed and available to you.
- The margin and total return, so you can decide whether a small lock is worth your time.
- Realistic volume. Steady numbers of small locks are what genuine price gaps look like, not daily windfalls.
- Stake rounding guidance, because oddly precise amounts can stand out and you may need to round while keeping the split balanced.
A calculator alone is useful if you already compare prices yourself, but it can only check what you feed it. It will not tell you that a price has moved since you looked.
Whatever you use, the app should give you information and leave the betting to you. You place each bet yourself in your own accounts, and you are responsible for checking each selection and stake before you confirm.
What risks remain even with a genuine lock?
A real lock removes the match result from the equation. It does not remove every risk. Be honest with yourself about these:
- Prices move. If you place the first bet and the second price drops before you confirm, the lock can shrink or turn into a small loss. Many arbers place the less stable price first and have both accounts open and funded before starting.
- Stakes get limited. Bookmakers can cap how much you can bet. A lock you can only half-stake is no longer balanced.
- Bets can be voided. Obvious pricing errors may be cancelled under a bookmaker's terms, which can leave the other side running on its own.
- Rule differences. Markets that look identical can settle differently, for example on tennis retirements or dead heats. Check each bookmaker's rules for the market.
- Mistakes happen. Wrong selection, wrong amount, a typo in the stake. Double-check before every confirm.

Frequently asked questions
Is a sure bets app the same as a betting tips app?
No. A tips app recommends one outcome and you lose your stake if it fails. A genuine sure bets app finds arbitrage locks, where every outcome is backed at different bookmakers so the return is set at the prices shown. Check whether the app gives a stake for each outcome; if it only names one selection, it is a tipping app.
How big is a typical lock?
Small. Most genuine locks return a percentage or two of the total staked, and AUOdds data shows a typical lock of about 1.4% over the last 30 days. On a $500 total stake, that is around $7. Any app advertising much larger, regular returns is likely selling tips or staking schemes rather than arbitrage.
Can a genuine lock still lose money?
Yes. If a price moves between your first and second bet, the lock can shrink or become a small loss. Stake limits, voided bets after pricing errors, different settlement rules and simple input mistakes can also cost you. A lock only locks in a return if every bet goes on at the prices shown.
How do I check a bookmaker in an alert is legal?
Use the ACMA's "Check if a gambling operator is legal" page to confirm an operator is permitted to offer services in Australia. Only use licensed Australian bookmakers for any lock, and be wary of any app that pushes you towards offshore sites or online in-play betting, which isn't offered to Australians.
