The available odds are displayed in list boxes; the best value odds appear at the top of the list. The app was launched in 2014 with a TV ad campaign, featuring Oddschecker’s brand characters Inspector Odds and his dog Checker, used to promote and communicate the benefits of the app. The main benefit being "In-App betting", which allows users to select the best value odds and then go on to place a bet with the selected firm without leaving the app, removing the usability problems associated with switching between different bookmaker’s apps. User of the mobile app have the fewest number of bookmakers to choose from. The initial selection was Bet365, Betfair, BetVictor, Ladbrokes, Paddy Power, Sky Bet and William Hill.

The Old Way

Every seasoned bettor knows the gut‑twist of chasing a line that vanishes the moment you place a bet. The market moves faster than a striker on a counter‑attack, and if you’re not watching the scoreboard of odds, you’re playing a game of chance with a blindfold. Here’s the deal: you need a radar that catches every flicker, every surge, every dip. Missing that signal is the difference between a profit and a loss. Look: not all odds aggregators are created equal. Our own personal highlights include the excellent odds, a broad range of sports and near-instant withdrawals, which adds real confidence when betting regularly.

Site B updates odds in milliseconds, a latency that makes you feel you’re watching the ball in slow motion while the market darts around you. It’s built for the quick‑draw bettor who needs to pounce the moment a line shifts. It offers fewer bookmakers, but the ones it does cover are the heavy hitters, and the speed compensates for the slimmer selection. Think of this one as the seasoned scout who knows every player’s hidden strengths. It uses AI to predict the next move of bookmakers, surfacing lines that are likely to improve in the next ten minutes. Their welcome offer includes £50 in free bets when you bet £10. You just need to enter ‘BETFRED50’ when you register and deposit (using a debit card) to be eligible. Once you’ve done that and placed a bet of at least £10 on any sports market (at odds of at least evens), you’ll be rewarded with the £50 of free bets.

The bet builder tool is available on a large range of sports on Paddy Power, including all the major US sports, and while the odds can be a little less competitive than some rival bookies, Paddy remains one of the top betting apps for bet builders and more. Betting exchanges offer punters a different way to bet. Rather than take on a bookie, punters bet against one another, setting the price an event will or will not happen.

Exchanges often provide bigger odds, with no house edge baked into the price, while bettors can trade to lock in a profit. The best mobile platform for all this can be found on Matchbook.
