Install the App in 3 Clear Steps
Android installation uses an APK file — around 30MB — because the app is not distributed through the Google Play store. On iOS, the process uses a browser-based shortcut that pins the app icon to your home screen without a separate download. Either way, the full lobby is reachable within a few minutes of starting. Make sure your phone has at least
100MB of free storage before you begin, and keep your langit87 account details ready so you can sign in immediately after the install completes.
- Step 1 — Get the APK or iOS Link — On Android, open langit87 in your browser and tap the app download button to save the APK file. On iOS, open the same URL in Safari and use the Share menu to add the shortcut to your home screen.
- Step 2 — Allow Install from Unknown Sources (Android Only) — Android will ask permission to install apps from outside the Play store. Go to Settings, find the security or app permissions section, and enable installation from this source. This step only appears once.
- Step 3 — Open the App and Sign In — Tap the langit87 icon on your home screen. Enter your account username and password, or use fingerprint login if you have already set it up. You arrive directly at the lobby.
