Reviewing Legal Mobile Sportsbook Apps

Looking for a first sportsbook, or to add a new one? We’ve researched and reviewed the top online sportsbooks, covering what matters most to bettors: bonuses, promotions, customer service, markets offered, fair odds, and the ease and speed of transactions. From the majors like DraftKings to FanDuel to innovative, newer books like Pointsbet, we’ve got the competitive insight and exclusive offers you’re looking for. 

Our Top Rated Books
We’ve reviewed more than a dozen sportsbooks and ranked them by evaluating the following categories: Bonuses & Promotions, Mobile app, Registering & Cashiering, Betting Options, & a Competitor Comparison. Here’s a high-level overview of how each book stacked up and why:
DraftKings is a heavyweight sportsbook with a sleek mobile interface, new live betting offerings and industry-leading sign-up promotions for sports bettors. Learn more about DraftKings promo codes, online bonus offers and why DraftKings is The Action Network's preferred book. Read MoreRight Arrow
The BetMGM Bonus Code is ACTION and using it will get you a refund on your first wager up to $1,000. BetMGM has compelling promotions, rapid payout speeds, and is highly recommended. Read MoreRight Arrow
PointsBet's app and site stand out as some of the best in the U.S. industry, from their sleek design to site navigation. They also offer great promotions and daily boosters, including some of the best odds in the market for the popular spread and over/under bets. If you're going to select only a few books from your state, PointsBet is one of our recommended options. Read MoreRight Arrow
FanDuel Sportsbook
Now available in several states. FanDuel is arguably the best legal sportsbook due to its stellar interface, wide range of betting options, and technical prowess to create a superior betting experience. It doesn’t hurt that they are an established sports brand with seemingly limitless marketing power. Read MoreRight Arrow
Unless you've been living under a rock your whole life, you're likely very familiar with the Fox brand — even if you didn't know they're now in the betting industry. They are a book worth checking out: While they seemingly cater to casual sports bettors by use of celebrity influencers, they actually offer solid prices across a variety of markets. While their odds boosts and promos are below industry standard, if you're a bettor who likes to price shop (and you should), FOX Bet is a worthy addition to your betting portfolio.

William Hill
William Hill, founded over 50 years ago in England, is one of the biggest names in sports betting worldwide. They are a veteran to the space, which should give new bettors confidence in their product. They have a good, easy-to-use website and app, and they consistently give out some of the best promotions in the U.S. market to help new customers build a bankroll early on. They're a worthy addition to your betting portfolio. Read MoreRight Arrow
theScore Bet
Building off an already top-of-the-line sports news and scores app, theScore Bet's mobile app is fast and extremely easy to use. Pair that with a strong deposit-match offer, promotions surrounding big events and a solid lineup of betting options, and you've got a highly recommended sportsbook. Read MoreRight Arrow
Parx is a trusted brand in the Pennsylvania betting space, and we expect they'll expand into other states in the coming years as well. Their sportsbook app isn't as sleek as those of the bigger brands like DraftKings or FanDuel, but given the number of different betting markets they list, they're a worthy book to add to your portfolio. They consistently offer solid new user sign-up offers, and we've consistently heard that bettors like the simplicity of the book, as well as fast deposits and payouts. Read MoreRight Arrow
BetRivers isn't the sleekest of sportsbooks, but they are available in many states, notably Illinois, one of the biggest to launch recently in 2020. They are a pretty standard large book: You'll find odds on just about every sport and market you could want, and odds on the primary sports are usually in line with most U.S. sportsbooks. They do advertise some negative expected value propositions for users. Still, if you're looking for another book at which you can line shop and take advantage of a sign-up offer, BetRivers is worth adding. Read MoreRight Arrow
SugarHouse isn't the sleekest of sportsbooks, but they — along with sister sportsbook BetRivers — are available in a ton of states. They are a pretty standard large book: You'll find odds on just about every sport and market you could want, and odds on the major sports are usually in line with most U.S. sportsbooks. They do advertise some negative expected value propositions for users, but if you're just looking for another book at which you can line shop and take advantage of a sign-up offer, SugarHouse is worth adding. Read MoreRight Arrow
Unibet is a popular European sportsbook and is starting to expand into the U.S. They're now live in four states — Arizona, New Jersey, Pennsylvania, Virginia and Indiana — and will likely continue to add new states as sports betting becomes more broadly legalized. Unibet isn't the sleekest sportsbook and lacks bonus offers and promos, but they are a reliable book that is reasonably easy to use and has solid customer service. Read MoreRight Arrow
An intuitive user experience makes WynnBET an inviting mobile option, and a simple but intriguing sign-up offer only adds to that invitation. It lacks a bit in its catalog of betting options, but with standard market odds and a highly-recognized name at its back, WynnBET is an all-around solid mobile sports betting option. Read MoreRight Arrow
888sport doesn't have the sleekest or fastest book in the industry, but they have been around a while and use Kambi, an odds provider also used by a lot of other U.S. books. That does mean you'll see similar odds and offerings at 888sport vs. other sportsbooks, but those options are fairly robust. They're one of the smaller sportsbooks in the U.S. right now but could look to be more aggressive in gaining market share both in New Jersey and by expanding into other states in years to come, which will be good for users. Read MoreRight Arrow
While bet365 is one of the biggest European books, they haven't pushed hard for U.S. market share yet. They've launched online betting in only New Jersey. They excel vs. their competition with simplicity and fair pricing. If you're looking for a sportsbook that will give you reliable odds and is easy to use, bet365 is a worthy addition to your betting portfolio. Read MoreRight Arrow

How To Evaluate and Select a Sportsbook

It’s essential to find a set of sportsbooks that fit your needs well, will keep you engaged, and provide the best odds and offers for your sports betting activity. We leveraged insights from our internal team and scraped and sourced external user review data to complete a robust analysis of each sportsbook to help your selection process.

Evaluation Criteria

Here are the factors considered, tested, and weighted in our sportsbook reviews:

Bonuses & Promotions

We took a look at sign-up offers, ongoing promotions, and the loyalty programs available from each sportsbook in legal states (e.g., Michigan or Arizona). Every book has its unique strengths: particularly compelling sign-up offers for new bettors, diverse markets and bet types, or lucrative VIP programs. We joined each book as a new user and pooled input from our team of passionate sports bettors with in-depth book experience to highlight where you can get the most from Bonuses & Promotions.

Mobile App

We downloaded available mobile apps for each sportsbook, completed their onboarding, and explored the app layout on mobile and mobile web. We noted any bugs or glitches experienced and compared ease-of-betting experience across books. Additionally, we performed an analysis of trends in user review data from the Apple App Store and Google Play. Trends from this research have been highlighted in our review to represent a broader audience of sports bettors and bring national user data and insight into our analysis.

Registering & Cashiering

It’s imperative to be able to trust a sportsbook with your money, and the experience of cashing in and out is a critical factor in selecting a sportsbook. The best books give various cashiering options, including credit and debit cards, PayPal, online banking, checks, and/or wire transfers. Additionally--bettors want these transactions to be fast and supported by responsive customer service. We tested each flow and available payment methods. We consider being able to cash out in under two days reasonable.

Betting Options

We looked into the types of bets offered (e.g., spreads, moneylines, totals) and available sports (e.g., NFL, CFB, NASCAR). Some books have more extensive sports availability and distinct bet types. Depending on your interests and preferences, there may be a collection of sportsbooks that help achieve your optimal sports betting experience, rather than just one.

Competitor Comparison

We lined up each sportsbook head to head vs. direct competitors, highlighting strengths and weaknesses. Some sportsbooks may excel in certain areas, like new betting markets, while struggling with user experience. In our reviews, you’ll see how the books line up.
