Android
Save Botrehan-Android.apk, open it, and allow install from this source if asked. The wall, likes, comments, and Share all run inside the app — including Google sign-in.
Install
Keep the wall with you.
Tap Download. A new tab saves the Android app, the iPhone profile, or the Windows app. Open that file and Botrehan runs on the device.
iPhone
Save the profile, open it, then Install under Settings → General → VPN & Device Management. Safari Share → Add to Home Screen also works.
Windows
Save Botrehan-Windows.exe and open it. The wall opens in its own window — likes, notes, and sign-in included. If Windows asks for WebView2, install it, then open Botrehan again.
Already on a phone? Share → Add to Home Screen installs Botrehan without a file. The wall stays public; only Share asks for the studio Gmail.
