Top Gambling Apps in the US

1. FanDuel: Best NJ sports betting app
2. DraftKings: Top PA sports setting app
3. SugarHouse: Best for variety of online casino games
4. BetMGM: Great for promos
5. Unibet: Unrivalled live betting experience

In New Jersey, Pennsylvania, West Virginia, Indiana, Oregon, and New Hampshire, it is 100% legal to use gambling apps.

You can open an online gambling app anywhere in state lines to both create an account and wager. But the number of options available in each state varies quite considerably.

For example, Oregon and New Hampshire are at one end of the scale with one single, state-run gambling app. New Jersey and Pennsylvania meanwhile are at the opposite end with choice aplenty.

FanDuel is a name that was long established in the US before legal sports betting arrived thanks to its daily fantasy sports (DFS) offering. But this isn’t the sole reason for FanDuel - live in NJ, PA, IN, WV - dominating the US market.

The FanDuel Sportsbook app has had a significant impact on the company’s success so far. With a superb user interface, a bottomless menu of wagers and a truckload of features and promotions, FanDuel is considered the best sports betting app in NJ for good reason.

If you’re in one of New Jersey, Pennsylvania, Indiana or West Virginia and want to bet online, it goes without saying FanDuel should top your list of sportsbooks gambling apps. Try for yourself, you won't be disappointed!

If anybody can lay claim to bettering what’s on offer at FanDuel, it’s the current market leaders in Pennsylvania, DraftKings,

As a fellow DFS provider turned sports betting powerhouse, DraftKings has benefited from its standing among US players to establish themselves early on in several US sports betting markets.

Like their great rivals, though, the DraftKings Sportsbook app doesn’t rely on reputation alone to appeal to the masses. They’re among the leading online gambling destinations due to a superior sports betting app.

A swift and seamless sign-up process gives instant access to the popular Stats Hub where you can back up your bet with a variety of stats and standings.

From depositing money to live betting and finding those all-important promotions, few companies can compete with the overall online gambling experience of the DraftKings Sportsbook app.

At the majority of online gambling apps, you can switch seamlessly between sports betting and online casino for the all-round online gambling experience. But some execute this better than others.

Thanks to several years as an online casino, you’ll have no problem finding the casino game you want to play at SugarHouse where there is a plethora available.

Winnings take no time to land in your account

The SugarHouse Sportsbook app is also very reliable when it comes to moving money with 12 different deposit methods to choose from. What pleased us most was the speed applied to the cash-out feature. Winnings take no time to land in your account.

Betting wagers across a range of sports in both North America and Europe are easy to find and listed in a clear, logical fashion. So in addition to the traditional big four sports in the US, you can bet on golf, tennis, cycling, rugby, cricket, Formula One, Aussie Rules Football, the list goes on.

Known as playMGM in the beginning, the casino and poker heavyweight has rebranded its sports betting arm to help differentiate its gambling offerings. A wise move in our eyes!

Easy navigation and numerous sign-up bonuses and promotions are two guarantees of the BetMGM sportsbook app which is far superior to the product launched initially.

The BetMGM app well worth a punt

While the elegance of the top sports betting apps will require more work and time, the BetMGM app is well worth a punt.

Despite dominating the European betting scene, Unibet is playing catch-up in terms of getting recognized in the states.

But once US bettors get their hands on one of the best online gambling apps on the market, expect the Swedish born company to more than earn its US stripes.

In terms of why we like the app itself, it has to be the simplicity of the general layout; at no point did we lose time trying to find what we were looking for. Additionally, there’s a clean and effective feel to how the text is displayed.

Nobody does live betting like Unibet though. Almost every sport offers in-play wagers and the odds are not only updated in the blink of an eye, but they're regularly the best priced too.

‘The World’s Favorite Sportsbook’ - as the UK bookmaker claims to be - is as complete an online sports betting app you will find.

From its extensive coverage of all sports, the best odds and lines and an array of other online options (see below) it’s clear why many regard Bet365 as the best online gambling app on the market.

For now, though at least, Bet365 is one of many new online gambling apps looking to become established and claim a share of the NJ market having only launched its US model in August 2019.

Right now, the Garden State is the only place you can legally use the Bet365 app. However, you can bet your bottom dollar Bet365 will play a prominent part in every legal online gambling market in the US before too long.

FanDuel is certainly the most popular US gambling app among Americans and it’s easy to see why. It’s our view that the simple and clean interface is the key factor in setting the FanDuel app apart from the rest of the competition.

From sign-up to depositing money, to the betting itself, the gambling experience is enjoyable and hassle-free. Having said that, though, we also believe a better welcome bonus would make for a stronger overall package.

And therein lies the answer to the question.

While it's useful to consider reviews from United Gamblers and other, similar sites, you are reading a subjective view. What we like about an online gambling app or sportsbook may not be the same for you and vice versa. You, as the player, need to download and experience the app for yourself.

In summary, we hope this article has provided a good level of insight into mobile gambling apps. But remember, there’s no one-size-fits-all when it comes to choosing an online gambling app.
