ArbVantage vs OddsJam: a comparison for Europe
OddsJam is one of the best-known betting tools in the United States, with a native iPhone app and a strong focus on US sportsbooks and player props. If you bet from Austria, Slovakia or elsewhere in Europe, the questions are different: which of your bookmakers are covered, in which currency and odds format, and at what price. Here is a factual comparison.
We make ArbVantage, so we are a party to this comparison. Every claim about the other product has a dated source below, and we say where it is ahead.

US vs European bookmakers
According to Preqin, OddsJam is aimed mainly at customers in the United States. Its strength is American sportsbooks, US leagues and player props. For a bettor in Europe that helps less than the long list suggests: US sportsbooks only accept bets while you are physically located in a state where online sports betting is legal. From Vienna, Bratislava or Madrid you cannot bet there, even if the prices appear in the feed.
What matters is whether the bookmakers you actually hold accounts with are covered. ArbVantage reads 36 international bookmakers today. From Austria, the usable ones today are mainly Tipico and William Hill; Unibet has left Austria, so its prices in the feed serve only as a market reference. Other popular Austrian books such as Admiral, bwin, Interwetten, tipp3 and bet-at-home, and the Slovak-licensed books such as Tipsport, Fortuna and Niké, are not in our feed yet and will come with a second odds source. Which European books OddsJam reads on its top plan is not stated in the App Store listing, so check that during its trial week.
The local rules differ too. In Austria a 5% betting fee applies to the stake; most bookmakers absorb it, some pass it on. Pinnacle, Betfair Exchange and Matchbook do not accept Austrian residents, and in Slovakia only operators licensed by the regulator ÚRHH may take bets. We price the fee in for bookmakers known to pass it on; none of the bookmakers in today's feed does, so check each bookmaker yourself. ArbVantage only suggests bookmakers you can use. More on the fee in the Austrian betting tax guide.
Example: reading American odds
US tools show American odds. A positive number is the profit on a 100 stake; a negative number is the stake needed to win 100. To convert to decimal odds:
+X → 1 + X/100 · −Y → 1 + 100/Y
Team A is +115 at one bookmaker, team B is −110 at another (no draw). In decimal: +115 = 1 + 115/100 = 2.15; −110 = 1 + 100/110 = 1.909.
Implied probabilities: 46.51% + 52.38% = 98.89%, so the margin is about 1.12%.
With €500 in total you stake €235.16 on A and €264.84 on B. Either result returns about €505.60, provided both bets are accepted at those odds and stand.
The maths is the same in any format; only the display changes. ArbVantage defaults to decimal odds and euros and can switch to American odds in Settings. How implied probability works is explained in implied probability.
Prices and trial
OddsJam sells several packages. The German App Store lists, among others, Gold and Sharp Money at €229.99 each, and Platinum and Positive EV at €599.99 each per month. The App Store description quotes dollar prices, for example Platinum at $499.99 a month. Prices on the website may differ, for example with annual billing. According to the App Store, every plan comes with 7 days free.
ArbVantage costs €97 a month for one plan with sure bets and middles. Value bets are coming soon and will be included in the same price. You get 14 days free with every feature; a card is required, and nothing is charged if you cancel before day 15.
A rough way to compare: the monthly turnover needed just to cover the fee. At an average net margin of 1% per sure bet (our model's assumption), €97 needs about €9,700 in total stakes a month, €229.99 about €23,000. That is arithmetic, not a forecast: real results vary and can be negative because odds change, bets get voided and accounts get limited.
Apps
OddsJam is ahead here. It has a native iPhone app with notifications. ArbVantage runs as a web app in your phone's browser today. Push notifications work on Android, and on iPhone from iOS 16.4 once you add the web app to your home screen. "Open" takes you to the bookmaker and copies the stake; on a computer, every leg shows a QR code that opens the bookmaker on your phone.
Native ArbVantage apps for iPhone and Android are in development. The plan: tapping a notification opens the bet, each leg opens directly in the bookmaker's app, and the stakes are copied for you. We will announce a launch date once it is fixed. What a good arbitrage app needs is covered in arbitrage betting apps.
Which one suits whom
OddsJam is likely the better fit if you bet in the United States, use US sportsbooks and player props, want positive-EV bets today, and want a native iPhone app now.
ArbVantage is likely the better fit if you bet from Austria, Slovakia or elsewhere in Europe, think in euros and decimal odds, want an interface in German or Slovak, and are looking for pre-match sure bets and middles at a lower monthly price.
