What is a casino web app? It is an online casino that runs inside your phone's browser, such as Safari or Chrome, instead of being installed from the App Store or Google Play. You log in to the same account, play the same kind of games and use the same cashier, but nothing is downloaded except the pages and games you open.
A casino web app is the casino's mobile site, sometimes saved to your home screen so it looks like an app.
It needs no download, no store approval and no particular iOS or Android version beyond a modern browser.
UK rules on licensing, ID checks, stake limits and game speed apply to web apps exactly as they do to native apps.
Store rules from Apple and Google don't apply to a website, so checking the Gambling Commission register matters more.
All five of our partner casinos publish native apps, ranging from 25.4 MB to 112.3 MB on iPhone.

What is a casino web app? A plain definition
A web app is software delivered through a website rather than installed from an app store. For a casino, that means you open the operator's site in your mobile browser, sign in and play. The site is built to fit a phone screen, so it feels much like an app, but the code lives on the operator's servers and loads each time you visit.
Casino web apps come in a few forms. The simplest is the mobile website itself. Some players save it to their home screen so it opens with an icon. A more advanced version, a progressive web app, can behave even more like a native app; our page on what a progressive web app casino is covers that. Short definitions of web app and native app are in our glossary, and the questions hub has related answers.
Casino web app vs native casino app
The biggest differences are in how you get the software and who checks it, not in the games or your money.

Why casinos offer a web app as well as a store app
A browser version reaches every phone, including ones too old for the native app. Coral and Ladbrokes, for example, need iOS 18.0 or later for their iPhone apps, so an iPhone that can't update that far is left with the website. Our page on casino apps on older phones looks at this in more detail.
The web route also works on devices without a casino app at all, such as a Windows PC or a phone without Google Play. And it avoids the store's approval process, which Apple says can take extra time for gambling apps because they are among the most regulated offerings it carries.
Do UK gambling rules apply to casino web apps?
Yes, in full. The Gambling Commission licenses the operator, not the app, so a British-facing casino needs a UK licence whether you reach it through a browser or a store. That means age and identity checks before you deposit or play (including free-to-play demos), a prompt to set a financial limit before your first deposit, and GAMSTOP participation.
Game design rules apply too. Online slots must take at least 2.5 seconds per spin, with no autoplay, turbo or slam-stop, and stakes are capped at £5 a spin for players aged 25 and over and £2 for 18 to 24-year-olds. Since 17 January 2025, other casino games must allow at least 5 seconds per game cycle, you can't play several games at once, and your net spend and time must be shown in real time. Our UK rules for casino apps section explains each.
Saving the site to your home screen gives it an icon without installing anything from a store. On an iPhone, open the site in Safari, tap the Share icon and choose Add to Home Screen. On Android, open the site in Chrome, open the browser menu and choose Add to Home screen or Install app, depending on your version.
Whether the saved icon opens full screen, remembers your login or does anything beyond a bookmark depends on how the casino has built its site. Our step-by-step guide to adding a casino web app to your home screen covers both platforms.
Native app sizes at UK casinos with web apps
All five casinos we partner with publish native apps as well as running websites you can use in a phone browser. If storage or an older iOS version is the reason you are considering a web app, these listing figures help you decide.
Phone tools such as Screen Time and Digital Wellbeing are built around installed apps, so they may not stop a casino site opening in a browser. If you want to block gambling on your phone, use something that covers websites too. GAMSTOP excludes you from every British-licensed operator's sites and apps for 6 months, 1 year or 5 years. Bank gambling blocks stop the payments, whichever route you use.
Gamban, a paid blocking app, says it blocks gambling sites and apps on all your devices. Our pages on Gamban and bank gambling blocks explain how they work. Free support is available from the National Gambling Helpline on 0808 8020 133.

Frequently asked questions
Is a casino web app the same as a mobile casino?
Broadly, yes. Mobile casino usually means the casino's website opened on a phone, and that is what most people mean by a casino web app. The term web app stresses that it behaves like an app inside the browser. Some casinos also offer a progressive web app that can be installed from the browser. Our explainer on whether you need to download an app covers when each makes sense.
Are casino web apps safe?
A web app is as safe as the operator behind it. A UK-licensed casino must follow the same rules in a browser as in a store app, including ID checks, fair terms and GAMSTOP. The difference is that no store has vetted a website, so check the Gambling Commission register before you sign up. Our page on whether casino apps are more secure than websites compares the two.
Do casino web apps have the same games as native apps?
Usually the games come from the same providers and run in the browser using HTML5, but an operator can choose to show different titles on different platforms. Check the lobby in both if a particular game matters to you. Return to player is set by each game, so look at the game's help screen for its figure. See are the games on casino apps the same as on desktop.
Can I use my existing account on a casino web app?
Yes. Your casino account is linked to you, not to a device or app, so you log in to the web version with the same details. Your balance, limits and verification status come with you. If you use both, any deposit limit you set in one applies to the other. Our page on using the same account on the app and website explains more.
Do casino web apps need my location?
A UK operator must make sure you are playing from somewhere it is licensed, so a web app may ask for location access through the browser or rely on other checks such as your network address. You can allow or refuse the browser's request, but refusing could stop you playing. Read more in why a casino app needs my location.
Are casino web apps free?
Yes. You don't pay to open a casino website or save it to your home screen; money only changes hands when you deposit through the cashier. Your mobile data plan still applies, and live dealer games stream video, so they use more data than slots. Native gambling apps must also be free under Apple and Google rules. Our guide to casino app data usage gives practical tips.
Can I get notifications from a casino web app?
It depends on the browser and on whether the casino's site supports web notifications, so don't assume it will. Native apps more commonly send push alerts. Either way, UK rules let you choose which marketing channels you receive, and you can turn off notifications in your phone or browser settings. Our guide to turning off casino app notifications shows how.
Is a web app better for someone who wants to gamble less?
It can help a little, because there is no icon tempting you on the home screen. But a browser makes it just as easy to reach any site, so it isn't a barrier on its own. Deposit limits, time-outs, GAMSTOP and bank gambling blocks are far stronger tools. If you are worried, our page on what to do if you are worried about your gambling is a good next step.
