Casino app storage space

Casino app storage space: the published sizes

The App Store shows a size for every app, and that's the cleanest way to compare casino apps. Here are the figures from the UK App Store listings for our five partners, with the minimum iOS version each one needs. The Coral Casino App Store listing (opens in a new tab) and PlayOJO's App Store listing (opens in a new tab) are typical of how the details appear.

Google Play works differently. It tailors the download to your phone, so it doesn't show one fixed size for everyone. Open the listing on your own Android phone to see the figure that applies to you. The rest of our casino app guides cover installing on both platforms.

Why some casino apps take up more storage than others

There's no single reason, and the stores don't break the figures down. What the listings do show is a pattern worth knowing:

• Sportsbook bundles. 10bet's app is filed under Sports on the App Store and carries in-play betting, Cash Out and live streaming alongside the casino. A combined app has more to carry. See standalone vs sportsbook apps.
• Device range. Coral's and Ladbrokes' iPhone apps also list iPad, Mac with Apple silicon and Apple Vision support.
• Extras built into the app. Casumo's listing mentions Face ID login, a home screen widget and haptic feedback; Coral's lists free-to-play games and rewards features.
• A lean, casino-only design. PlayOJO's app is a casino-only product and, at 25.4 MB, is the smallest of the five.

Size and game choice aren't directly linked either. PlayOJO is the smallest download but still lists slots, jackpot slots, bingo, table games and live casino in its app description. Our standalone casino apps list explains why some players prefer an app that does one job.

How much space do you need for one, two or five casino apps?

Adding up the listed sizes gives a useful starting point. Treat these as minimums, because each app also stores data as you use it and needs spare room to install updates.

Even all five together come to well under half a gigabyte, so on most phones storage only matters when the device is already nearly full. That's also when updates fail, which is the more common problem. Keep a little headroom: the NCSC recommends (opens in a new tab) installing app and system updates as soon as they're available, and you can't do that without space.

Coral and Ladbrokes are both run by LC International Limited (Entain), so one person may not be able to open new accounts at both. Check before installing two apps you might not be able to use. See Coral vs Ladbrokes.

How to check a casino app's storage use on iPhone

iOS shows two numbers for every app: the app itself and its documents and data. The second figure is the part that grows.

1. Open Settings and tap General.
2. Tap iPhone Storage (iPad Storage on an iPad) and wait for the list to load.
3. Scroll to the casino app and tap it.
4. Read App Size and Documents & Data. Together they show what the app takes up now.
5. From here you can choose Offload App or Delete App if you need the space.

Offloading removes the app but keeps its documents and data, so reinstalling puts you back where you were. Deleting removes both. Neither affects your casino account, because your balance and history are held by the operator. Our iPhone casino apps page covers other iPhone settings.

Checking casino app storage on Android

Android menus vary by manufacturer, but every recent phone shows storage per app.

1. Open Settings and tap Apps (on some phones, Apps & notifications).
2. Find the casino app in the list and tap it.
3. Tap Storage (sometimes Storage & cache).
4. Look at the app size, user data and cache figures.
5. Use Clear cache to free temporary files, or Clear storage to reset the app completely.

Clear cache is the gentle option. Clear storage wipes the app's saved data on the phone, so you'll need to log in again. Our step-by-step guide on how to clear a casino app cache explains which to use when, and the Android phones page covers wider settings.

Freeing up storage without losing your casino account

Your casino account doesn't live on your phone. Deposits, withdrawals, limits and self-exclusions are held by the operator, so tidying up storage can't cost you money. Pick the option that fits.

If you're deleting for good, read how to delete a casino app and what happens to your balance if you delete the app. If you'd rather keep access without the download, adding a casino web app to your home screen takes almost no space.

Low storage problems in casino apps and how to fix them

Phones get unpredictable when storage is close to full. These are the usual symptoms and what to try first.

Does a bigger casino app mean better games or odds?

No. The download size reflects what's built into the app, not the quality of the games or your chances. RTP is set by each game, and apps don't carry lower RTP by default; open a game's help screen to see the figure for the version you're playing. Our guide to finding a game's RTP in an app shows where to look.

The house edge applies whatever app you use. On a slot with a 96% RTP, the expected loss is 4p for every £1 staked, so 300 spins at 10p (£30 staked) has an expected cost of about £1.20. Real sessions swing far either side of that, which is why limits matter more than app choice. Set one with our guide to deposit limits in a casino app.

Managing storage when you have several casino apps

Several apps mean several sets of updates, notifications and logins, and storage creep is the least of it. A shorter list is easier to keep under control. Think about which app you actually use, and offload or delete the others.

• Keep one or two apps that match how you play, rather than one for every welcome offer.
• Turn off notifications you don't want; see how to turn off casino app notifications.
• If you want to cut back, app timers and blocks help: see blocking casino apps with Screen Time.
• Read managing several casino apps for keeping track of balances and limits across accounts.

Casino apps by storage space with a welcome offer

If space is tight, PlayOJO is the lightest of our partner apps at 25.4 MB on iPhone. Coral and Ladbrokes are dedicated casino apps at just over 100 MB each and need iOS 18.0. The small download casino apps list goes further. 18+ and terms apply to all offers.

• PlayOJO (25.4 MB): new UK customers (excluding Northern Ireland) making a first deposit of at least £10 get 80 free spins on Big Bass Bonanza, 10p each. No wagering, winnings paid in cash; can't be combined with other offers; only via the designated offer link.
• Ladbrokes (101.2 MB): new customers who deposit and spend £10 or more on slots get 50 free spins a day for the first 10 days (maximum 500), 10p each on selected games. Claim before 23:59 each day; valid 7 days; no wagering. Prepaid cards, PayPal, Paysafe, Neteller, Skrill and Moneybookers deposits don't qualify.
• Coral (101.6 MB): new players, 1 October 2026 to 1 February 2027. Deposit (some methods excluded) and bet £10 or more on slots for 100 free spins on selected games, 10p each. Accept within 48 hours; valid 7 days; no wagering on spin winnings. Neteller, PayPal, Paysafe, Skrill, prepaid cards and certain debit cards don't qualify.

Spin offers are slot offers only; table and live games are often excluded. For context, 10bet's combined sportsbook and casino app is the largest at 112.3 MB, as its App Store listing (opens in a new tab) shows.
