iOS DownloadHow to Install on Android
Installing the cko444 app on Android requires a slightly different process, as the APK file must be downloaded directly from the cko444 website rather than the Google Play Store. Follow the steps below:
Enable installation from unknown sources
Go to your phone's Settings → Security → Unknown Sources, or enable "Allow installation from this source". This is only required for APK installation.
Download the cko444 APK
Click the "Android Download" button above and let the APK file save to your phone's Downloads folder.
Open the Downloads Folder
Open the File Manager app on your phone and go to the "Downloads" folder. Locate the cko444.apk file.
Tap the APK file
Tap the file to open the installation window. Tap the "Install" button and wait 30–60 seconds.
Open the app and log in
Once installation is complete, the cko444 icon will appear on your Home Screen. Open the app, log in, and start playing.
Security Note: It is good practice to turn off the "Unknown Sources" setting again after installing the APK. Avoid installing APKs from unknown sources other than cko444.
How to Install on iOS
Installing the cko444 app on an iPhone or iPad is relatively straightforward. iOS has stricter security measures, so the installation steps may differ slightly.
Open the cko444 site in Safari
Use Safari on your iPhone or iPad. The download button may not work correctly in other browsers.
Tap the iOS download link
Tap the "iOS Download" button. You will be prompted to install it as a web app on your iOS device.
Add to Home Screen
Tap the Share button in Safari (at the bottom center) → select "Add to Home Screen" → tap "Add".
Open the App from Your Home Screen
A cko444 icon will appear on your home screen. It runs in full-screen just like a native app.
iOS Tips: The cko444 app also works as a PWA (Progressive Web App) on iPhone. Once added to your Home Screen, you can launch it directly from the icon without opening a browser.

Browser vs. App — Which Is Better?
Cko444 works great on mobile browsers too. So why download a separate app? The answer is simple — the experience is just different.
The app loads much faster because some resources are stored on your device. You will receive push notifications, which are not possible in a browser. Fingerprint login is available. You can launch it directly from your Home Screen. And most importantly — the full screen is used with no browser bar at the top.
If your device is low on storage or you prefer not to download an app, the cko444 mobile website is fully functional. You can enjoy all features through any modern mobile browser.
How do I update the app?
The cko444 app is updated regularly. Updates are released when new games are added, bugs are fixed, or security improvements are made. You will receive an update notification automatically when you open the app.
To update on Android, download and install the new APK — it will install over the existing app without erasing your data. On iOS, the web app updates automatically with no action required.
Good to Know: Downloading the cko444 app does not require a new account — just log in with the same credentials you use on the website.
