Get Lutazu

Install on Windows

Works on Windows 10 and 11 (64-bit). About 120 MB.

1. Press Download for Windows above. LutazuSetup.exe saves to your Downloads folder.
2. Open LutazuSetup.exe. If Windows shows "Windows protected your PC", click More info, then Run anyway. This appears for new apps that aren't widely downloaded yet.
3. Lutazu installs in a few seconds and opens. It adds a desktop shortcut and a Start menu entry. Closing the window keeps it in the system tray, like other chat apps.

Seeing "Smart App Control blocked an app"? Some Windows 11 PCs only allow apps with a digital signature, and ours is on the way. Until then, install Lutazu from your browser. It works the same and updates itself.

Can't run .exe files (for example on a school laptop)? Install it from your browser instead.

Install on Mac

Chrome or Edge, or Safari on macOS Sonoma and newer.

1. Use Google Chrome or Microsoft Edge and press the red Install Lutazu button above, then Install.
2. No popup? Click the install icon Install at the right end of the address bar. Or open the browser menu ⋮ and choose Install Lutazu. In Chrome it's under Cast, save and share; in Edge under Apps.
3. Lutazu opens in its own window. It appears in Launchpad and your Applications folder. You can keep it in the Dock.

Using Safari? Open the File menu (or the Share button) and choose Add to Dock.

Install on Linux

64-bit Linux (Ubuntu, Fedora, Debian, Arch, Mint and others).

1. Press Download for Linux above. Lutazu-linux.tar.gz saves to your Downloads.
2. Open a terminal in Downloads and run tar -xzf Lutazu-linux.tar.gz
3. Start it with ./Lutazu-1.1.0/lutazu. If it doesn't open, run ./Lutazu-1.1.0/lutazu --no-sandbox

Prefer not to use a terminal? Install it from Chrome or Edge instead. One click, and it updates itself.

Install on Chromebook

Works on every Chromebook, including school ones that allow apps.

1. Press the red Install Lutazu button above, then Install.
2. No popup? Click the install icon Install in the address bar, or the menu ⋮ → Cast, save and share → Install page as app.
3. Find Lutazu in your Launcher and pin it to the shelf.

Install on Android

Android 5 and newer. A real app, about 1 MB.

1. Tap Download for Android above. Lutazu.apk downloads.
2. Open it from your notifications or the Files / Downloads app. If your phone asks, allow your browser to install unknown apps (this is how apps from outside the Play Store install).
3. Tap Install, then Open. Lutazu is now on your home screen and in your app drawer.

If Play Protect asks, choose Install anyway. It says this for apps that aren't on the Play Store yet. Or install it from Chrome with no download.

Install on iPhone & iPad

Apple only lets apps like this be added from the Share menu. It takes 10 seconds.

1. Open this page in Safari (Chrome and Edge also work on iOS 16.4+).
2. Tap the Share button at the bottom (or top on iPad).
3. Scroll down and tap Add to Home Screen, then Add.
4. Open Lutazu from your home screen. To get notifications, turn them on inside the app.
